Fireplace Damper Jammed Shut with Fire Burning: Smoke Inversion Triage¶

I-masonry ebaswa ngamaplanga okanye indawo yomlilo eyakhiwe kwifektri isebenza kwi-convective buoyancy yendalo, eyaziwa ngokuba yi-chimney stack effect. Iirhasi ezishushu eziveliswa zizigodo ezivuthayo azixinene kangako kunomoya ongqongeyo, zenza indawo yoxinzelelo oluphantsi enyusa umsi ngebhokisi yomqala, idlule ishelufu yomsi, ikhuphe itshimini. Kweyona ndawo imxinwa kulo mjelo wokukhuphela kuhlala isidambisi somqala, intsimbi enzima okanye ipleyiti enesitampu eyenzelwe ukutywina itshimini xa ingasetyenziswa. Xa ipleyiti yedamper ijika kubushushu obugqithisileyo, ibambe iidiphozithi zekhreosote zekharbhoni, okanye iwise ivale phakathi ekutshiseni ngenxa yentambo eqhawukileyo okanye uqhagamshelo lomatshini oluvaliweyo, idrafti yetshimini iyawa ngoko nangoko.

Ukuvalwa kwedamper phakathi ekutshisweni kuguqula iziko elisebenzayo libe ngumsi osebenzayo wangaphakathi kunye nejenereyitha yerhasi eyityhefu kwimizuzwana nje. Ayikwazanga ukubaleka ukuya phezulu ngeflue evaliweyo, izinto ezivuthayo ezitshisa kakhulu (kuquka icarbon monoxide ebulalayo, iacrolein, formaldehyde, ihydrogen cyanide, kunye nemicroscopic particulate matter) ibetha ipleyiti yesidambisi shushu, qengqeleka ihle isuka kwishelufu yomsi, kwaye igqabhuke idlule kumphezulu weziko ukuya kwindawo yokuhlala. Oku kutshintsha ngesiquphe kweatmospheric kuzalisa iindawo zokuhlala ngokumfamekisa, umsi onetyhefu, kuvule iialam ze-ionization yasekhaya, kubangele izitshizi zomlilo ezizenzekelayo zokuhlala, kwaye kudala ingozi yomlilo yangoko ukuba ubushushu obukhazimlayo bakheka emva kwesakhelo somthi.

Ukulawula ijem yedamper ngelixa umlilo uvutha kufuna ulawulo olukhawulezayo lwekhemistri yokutsha kunye nemisinga yomoya yangaphakathi. Iimpendulo zethuku, ezinjengokujula iiemele zamanzi abandayo phezu kweenkuni ezivuthayo, zivuse uqhushumbo lomphunga ovelisa amanzi abilayo, amalahle abhabhayo, kunye nothuthu kwigumbi lokuhlala ngelixa uqhekeza iileyiti zezitena zomlilo. Abanini bezakhiwo kufuneka bawacinezele ngokukhuselekileyo amadangatye ngaphandle kokudala umphunga oqhumayo, bamisele umoya ongalunganga womoya, kwaye bakhusele ipleyiti yedamper exineneyo ngomatshini besebenzisa izixhobo ezifanelekileyo zokukhusela.

Yenza oku ngoku¶

1. Khupha bonke abantwana, izilwanyana zasekhaya, abahlali abadala, kunye nabantu abaneemeko zokuphefumla kwisakhiwo ngokukhawuleza. Khuthela amalungu asemngciphekweni ngaphandle kumoya omtsha. Umsi ophuma kwiinkuni ezivuthayo uqulethe i-carbon monoxide ephezulu kunye nezinto ezicaphukisa ukuphefumla ezibangela i-bronchospasms kunye ne-carbon monoxide toxicity kumagumbi avaliweyo.
2. Cima isifudumezi esembindini, umoya wokungenisa umoya, kunye nenkqubo yokupholisa umoya (HVAC) kwi-thermostat. Ukuseta i-thermostat KUVALIWE kumisa i-fan yesibambi somoya esisembindini. Ukuqhuba inkqubo ye-HVAC ngexesha loguqulo lomsi wangaphakathi lufunxa amasuntswana omsi kwiigrille zomoya ezibuyayo, ukusasaza i-soot kunye nekhabhon monoxide kwigumbi ngalinye endlwini.
3. Wucime umlilo ngokukhuselekileyo usebenzisa isodiyam bicarbonate (isoda yokubhaka) okanye isanti yokudlala eyomileyo. Lahla izixa ezikhulu zesoda yokubhaka okanye isanti eyomileyo ngqo phezu kweenkuni ezivuthayo kunye nokhuko olushushu. Isoda yokubhaka ikhupha irhasi yekharbon diokside ekuboleni kobushushu, ukucima amadangatye ngaphandle kokuvelisa uqhushumbo oluyingozi lomphunga okanye uthuthu olubhabhayo.
4. Vala iingcango zeziko zeglasi ngokuqinileyo ukuba iziko lixhotyiswe ngazo. Ukuba iziko linobushushu obupholileyo okanye iglasi yeceramic iingcango eziphindwe kabini, zivale ngokupheleleyo ngelixa uvale iminyango yomoya esezantsi. Ukuthintela ioksijini ye-atmospheric kwibhokisi yomlilo kuphelisa inkqubo yokutsha kwaye kunciphisa ukungena komsi kwigumbi.
5. Misa indawo yokuphuma komoya enqamlezileyo ngokuvula iifestile kwicala elingaphantsi lomoya (i-leeward) legumbi kunye nokufakwa kwefeni yokuphuma ephumayo. Misa ifeni yebhokisi ephathekayo kwifestile yangaphandle evulekileyo evuthela ngaphandle ukudala uxinzelelo olubi lomoya wangaphakathi. Gcina iingcango zangaphakathi kumagumbi okulala angachaphazelekiyo zivaliwe ukunqanda ukufuduka komsi kwikhaya lonke.
6. *Zama ukuvulela ngomatshini ukuvula ipleyiti yedamper usebenzisa iitongi zentsimbi enzima okanye ipoker. Ukunxiba iiglavu zesikhumba esinzima esigqunyiweyo kunye nokhuseleko lwamehlo, faka incam yentsimbi ende yepoker kumlebe wepleyiti yedamper kwaye utyhale phezulu ngokuqinileyo. Ukuba ipleyiti iphakamisa, jika intsimbi yepoker okanye iqhekeza lombhobho wentsimbi enzima phantsi kwepleyiti ukuze uyibambe ivuleke kwaye ubuyisele uyilo oluphezulu lweflue.
7. *Fowunela inombolo yakho yonxunguphalo yasekuhlaleni ukuba umlilo awunako ukucinywa okanye ukuba isifuba setshimini sivakala sishushu ngokugqithisileyo. Ukuba umsi uyaqhubeka nokugalela kwigumbi, ukuba ii-alam zekhabhon monoksayidi zivakala kwikhaya lonke, okanye ukuba i-drywall ephezu kwe-fireplace mantel ivakala ishushu xa ubamba, phuma ngokukhawuleza kwaye ufowunele iinkonzo zikaxakeka ngaphandle.

I-anatomy yobuchwephesha ye-chimney dampers, iishelufu zomsi, kunye ne-flue aerodynamics¶

Ukusombulula imeko engxamisekileyo ye-damper jam kufuna ukuqonda okucacileyo kwejiyometri yomqala wetshimini, ulungelelwaniso lonxibelelaniso, kunye nemigaqo ye-aerodynamic convective.

Iindlela zokudambisa umqala: Ulawulo lwepoker, iiratshi ezijikelezayo, kunye nonxibelelwano lwe-lever¶

Isidambisi somqala sihlala phezulu kwibhokisi yomlilo, ngqo ngaphezulu kwegumbi lokutsha kunye nangaphantsi kwegumbi lomsi. Izidambisi zomqala zifakwe kwiinkqubo ezintathu eziphambili zohlengahlengiso:

• I-poker-control (i-push-tsalo) i-damper: Ifaka ipleyiti yentsimbi efakwe kwipivot yangasemva. Ingalo yentsimbi egobileyo, enenotshi iye ezantsi kwibhokisi yomlilo ephezulu. Umsebenzisi usebenzisa i-fireplace poker ukutyhalela ingalo phezulu, ukuhuka iinotshi phezu kwentsimbi yentsimbi ukubamba ipleyiti ivuleke kwii-engile ezahlukeneyo. Ukungaphumeleli kwenzeka xa ingalo enotshisiweyo ityibilika kwisikhonkwane okanye ibopheleleke kumle onzima.
• Ulawulo lwe-ratchet ejikelezayo: Usebenzisa i-screw shaft enemisonto okanye isixhobo se-iron worm esetyenziswa sisitshixo esijikelezayo okanye isiphatho esiphumela kumphezulu weziko ngaphezu kwendawo evulekileyo. Ukuguqula isiphatho kujikelezisa isixhobo somsundululu, siphakamise ipleyiti yedamper. Ukusilela kwenzeka xa ukwanda kwe-thermal kubamba igiya yeentshulube, okanye xa amazinyo egiya yentsimbi ehluma phantsi kwetorque egqithisileyo.
• Isixhobo sokufudumeza esifakwe kwi-Lever: Dibanisa ipleyiti yedamper kwisiphatho sesixhasi esixhonywe ngaphakathi kwibhokisi yomlilo esecaleni. Ukuhambisa i-lever phambili okanye ngasemva ivula kwaye ivale ipleyiti. Ukungaphumeleli kwenzeka xa i-creosote ikhula malunga ne-pivot pin, itshixa i-lever kwindawo evaliweyo.

I-dampers yokutywinwa okuphezulu kunye neendibano ze-cable spring-return-return¶

Iindawo ezininzi zokucima umlilo zamatye ziphinde zafakelwa ngokutsha ngezidambisi manzi zetshimini ezitywina phezulu (ezifana neLyemance okanye iinkqubo ze-Lock-Top). Endaweni yepleyiti yomqala, isidambisi-manzi esitywina phezulu sine-aluminiyam okanye isivalo sentsimbi egxunyekwe ngqo kwitshimini yesithsaba kumgca wokuphahla:

1. Isixhobo sokulayisha entwasahlobo: Umnqwazi wedampa onyuswe phezulu ubanjwe kwindawo evulekileyo ngemithombo yolwandiso yentsimbi enzima okanye iingalo ezishukumayo.
2. Ukuqhuba kwentambo yentsimbi eqhubekayo: I-1.6-millimeter ukuya kwi-2.4-millimeter (1/16-intshi ukuya kwi-3/32-intshi) intambo yocingo olulukiweyo olulukiweyo olulukiweyo lubaleka ukusuka kumnqwazi wophahla, ukuhla kubo bonke ubude bombhobho wetshimini, ngegumbi lomsi, ukuya kwibhokisi yomlilo.
3. Isibiyeli sebhokisi yomlilo: Isiphelo esisezantsi seegwegwe zentambo kwibrakethi yobhedu okanye yentsimbi efakwe kudonga lwebhokisi yomlilo. Ukutsalela intambo ukuya ezantsi kuvala ikepusi yophahla ngokuchasene negasket yerabha ye-silicone; ukukhulula intambo kuvumela imithombo ukuba itsale i-cap ivuleke.
4. Iindlela zokusilela: Ukuba intambo yentsimbi engatyiwayo isuka kumhlwa okanye kukudinwa bubushushu ngaphakathi kwegumbi lomsi, okanye ukuba i-slug esezantsi ekrunekileyo yobhedu siyatsala siphuma kwisibiyeli sebhokisi yomlilo, isixhobo sasentwasahlobo esingaphezulu kufuneka sitsale isidambisi sivuleke. Nangona kunjalo, ukuba i-creosote ikhazimula phezu kwehenjisi ephezulu okanye ukuba uphahla luphuma ngenxa yokudinwa kwe-thermal, i-damper cap enzima ivala isithsaba se-flue, sithintele konke ukuphuma kwamanzi.

Ishelufu yomsi kunye nokwakheka kwe-vortex ye-aerodynamic¶

Ngokuthe ngqo ngasemva komqala isidambisi shushu kuhlala ishelufu yomsi eyenziwe ngamatye, inqwanqwa lesitena esithe tyaba eliqhele i-150 ukuya kuma-300 eemilimitha (6 ukuya kwi-intshi ezi-12) ubunzulu. Ishelufu yomsi idlala indima yomatshini kwitshimini ye-aerodynamics:

• Isithintelo se-Downdraft: Umoya opholileyo wangaphandle ozika kwiindonga zangaphandle zetshimini ubetha ishelufa yomsi ethe tye, ujikela phezulu kwivortex ejikelezayo ethi ibambeke kumsinga wokuphuma onyakazelayo ize iphinde ibuyele ngaphandle.
• Ukufumba kobutyobo: Ithala lomsi lisebenza njengendawo yokugcina udaka oluwayo, imvula, uthuthu olulahliweyo, iintaka ezifileyo okanye iindlwane zezilwanyana. Ukuba indawo yomlilo ayihoywa, amashumi eminyaka yesoot kunye nenkunkuma ewileyo iqokelelana kwishelufu yomsi. Xa ipleyiti yokudambisa umqala ivulwa okanye ivaliwe, le mfumba yobutyobo inzima iphalala kwiingoma zefreyimu emdaka, ivala ipleyiti ngokwasemzimbeni.

Ifiziksi ye-thermal warping kunye nokubopha i-creosote¶

Ukuqonda ukuba kutheni i-damper jams ngelixa umlilo uvutha kufuna ukuhlalutya i-thermodynamics yensimbi kunye neenguqu ze-creosote zekhemikhali phantsi kobushushu obuphakamileyo.

Ukwandiswa kwe-Thermal kunye ne-metallurgical warping¶

Intsimbi yentsimbi yintsimbi equlethe i-2 ukuya kwi-4 yeepesenti yekhabhoni kunye ne-1 ukuya kwi-3 yeepesenti yesilicon. Ngelixa ibonisa amandla aphezulu okucinezela kunye nokugcinwa kwe-thermal okugqwesileyo, ine-coefficient ephezulu yokwanda kwe-thermal kunye ne-ductility ephantsi.

Ngexesha lomlilo oqhelekileyo weenkuni ezilawulwayo, amaqondo obushushu kumqala afikelela kuma-200 ukuya kuma-350 ngokukaCelsius (ama-392 ukuya kuma-662 ngokukaCelsius). Nangona kunjalo, ukuba umthwalo omkhulu womthi oqinileyo owomileyo, intlaka ethambileyo (efana nompayina okanye ifir), okanye inkunkuma yasekhaya etshayo (enjengebhokisi yekhadibhodi okanye iphepha lokusonga) ubushushu bomqala bunokunyuka budlule kwi-600 degrees celcius (1,112 degrees Fahrenheit) kwimizuzu nje embalwa.

Kula maqondo obushushu, ipleyiti yentsimbi ecekethekileyo okanye ipleyiti yokudambisa isitampu ikhula ngokukhawuleza kunesakhelo esijikelezileyo sentsimbi esizinziswe kudaka lwemasonry. Ipleyiti ye-damper yandisa ngaphandle kwimigudu yesikhokelo esisecaleni. Ngenxa yokuba ipleyiti ayinako ukunwebeka ecaleni ngokuchasene nesiseko sezitena eziqinileyo, ikhulula uxinzelelo lwe-thermal ngokugoba okanye ukujikela phezulu okanye ezantsi. Nje ukuba ipleyiti iphume kwinqwelo-moya, izikhonkwane zepivot zayo zibophelela kwisokethi zazo, zitshixe isidambisi endaweni yayo.

Ukutshintsha kwesigaba sekhemikhali kwinqanaba lesithathu le-creosote¶

ICreosote ngumxube ontsonkothileyo weehydrocarbons zomthi ezingatshiyo, iitar, kunye neeasidi eziphilayo eziveliswa kukutsha okungaphelelanga. Ibakho ngokwamanqanaba amathathu ahlukeneyo:

1. Inqanaba Lokuqala (Umlu): Umgubo othambileyo, oncatshukileyo omnyama oxukuxa ngokulula.
2. Inqanaba leSibini (Iifleyibhile): Iiflakthi ezityumkileyo, eziqhokayo ezimnyama ezityebileyo ngetela yomthi.
3. Inqanaba leSithathu (Ukumenyezela): Iheyibhile eshinyeneyo, eqinileyo, efana netela egquma intsimbi kunye nomgangatho owenziwe ngamasuntswana njengeglasi emnyama.

Xa iziko lihlala libanda, iNqanaba leSithathu lekhreosote ligqume izikhonkwane zepivot ezimanzi kunye neengoma zefreyimu ziqinile. Njengoko umlilo ufudumeza umqala, i-creosote ifikelela kwiqondo lobushushu elithambileyo, eliphakathi kwama-80 kunye ne-150 ngokukaCelsius (176 kunye ne-302 degrees Fahrenheit). Umkhenkce ujika ube yitela ebonakeleyo, encangathi.

Ukuba ipleyiti yedamper ilungelelaniswe ngokuyinxenye okanye ingqutywe phakathi ekutshiseni, le tela yolwelo iqukuqela kwizithuba zeehenjisi. Ukuba umlilo uqina ngokukhawuleza, itela iyabila isuka kumalungu ayo aguquguqukayo, ngokukhawuleza ipholiseke ibe yimatrix eshinyeneyo, enecarbonized coke. Le carbon bond isebenza njenge-epoxy yobushushu obuphezulu, itshixa ipleyiti yentsimbi kwisakhelo.

Iingozi zempilo kunye netyhefu ye-atmospheric yokuguquguquka komsi wangaphakathi¶

Uguqulo lomsi olusuka kwisidambisi-ziko esixineneyo asiyonkathazo nje yokunuka; yingxaki yetyhefu ekhawulezileyo. Umsi wokhuni unamakhulukhulu eekhompawundi zeekhemikhali ezicacileyo, uninzi lwazo ezibeka iingozi zokhuseleko ebomini kwiindawo ezivaliweyo zokuhlala.

Toxic Smoke Inversion Components:
  ├── Carbon Monoxide (CO): Colorless, odorless; binds hemoglobin 200x tighter than oxygen; causes rapid neurological collapse
  ├── Hydrogen Cyanide (HCN): Produced by burning nitrogenous materials; blocks cellular ATP production
  ├── Acrolein & Formaldehyde: Highly reactive aldehydes; cause acute airway burns, coughing, and pulmonary edema
  └── Fine Particulate Matter (PM2.5): Penetrates deep into lung alveoli, entering bloodstream directly

Ityhefu yeCarbon monoxide Dynamics¶

Ikharbhon monoxide (CO) yirhasi engenavumba, engenambala eveliswa ngobuninzi obukhulu xa umlilo ubhuqwa yindlala yokuphuma komoya. Xa i-damper ivaliwe, i-oksijini ngaphakathi kwibhokisi yomlilo iyancipha ngokukhawuleza, ibangela ukutshisa kutshintshe ukusuka kwi-oxidation ecocekileyo ukuya kwi-oxygen-lamba yokutshisa. Amaplanga aqhumayo avelisa ikharbon monokside ngokuphindwe kalishumi kunomlilo ovuthayo.

Xa uphefumlelwa, ikharbhon monoxide ibophelela kwihemoglobin yomntu enobudlelwane obuphindwe kangangama-200 ukuya kuma-250 ngaphezu kweoksijini, yenze i-carboxyhemoglobin (COHb). Oku kuthintela ukuthuthwa kweoksijini kwizitho ezibalulekileyo. Kwigumbi lokuhlala elivaliweyo elinendawo yokucima umlilo, ukugxila kwe-CO yangaphakathi kunokunyuka kudlule iinxalenye ze-400 ngesigidi kwimizuzu emihlanu. Kolu gxininiso, abahlali bafumana intloko ebuhlungu engaphambili, isiyezi, isicaphucaphu, kunye nokuphazamiseka kwemoto kwimizuzu engama-20, okukhokelela ekubeni bangabikho zingqondweni kunye nokufa kwiiyure ezimbini.

Ukutsha kwezinto ezithile kunye neekhemikhali zomoya¶

Umsi womsi womthi (PM2.5) uqulathe amasuntswana ekhabhoni amancinci anedayamitha ye-aerodynamic engaphantsi kwe-2.5 micrometer. Ezi ngqungquthela zidlula ukhuseleko oluphezulu lokuphefumula (i-cilia yeempumlo kunye ne-mucous membranes) kwaye zingene nzulu kwiingxowa ze-alveolar zemiphunga.

Kwangaxeshanye, ukophuka kwe-thermal ye-wood lignin kunye ne-celluloses kukhupha i-acrolein (i-propenal) kunye ne-formaldehyde. I-Acrolein yintlupheko enzima yokuphefumla eyenza ukukrala okukhulu (ukukrazula kwamehlo), i-chemical rhinorrhea, kunye ne-bronchoconstriction ebukhali. Ukuphefumla umsi womthi ogxininisiweyo kwigumbi elingenamoya kubangela i-chemical tracheobronchitis kunye ne-non-cardiogenic pulmonary edema, efuna ukungenelela kwezonyango ngokukhawuleza.

Uvavanyo lokuxilonga kunye neenkqubo ze-mechanical unjamming¶

Ukuba umlilo ucinezelwe okanye uqukunjelwe, landela ezi protocols zoomatshini ukuze ufumanise ijam, ukhulule ipleyiti, kwaye ubuyisele idrafti yetshimini ngokukhuselekileyo.

Inyathelo ngenyathelo loxinzelelo lomlilo, ukungazinzi, kunye neeprothokholi zokungenisa umoya¶

Ukulawula ngokucwangcisiweyo imeko engxamisekileyo yaseziko kufuna ukuba kwenziwe izigaba ezithathu ezicacileyo zokusebenza: ukucinezela umthombo wokutsha, ukuphelisa indlela yokukhupha umbhobho, kunye nokucoca ungcoliseko oluyityhefu lomoya.

Izixhobo zokhuseleko ezifunekayo, izixhobo kunye nemathiriyeli¶

Hlanganisa ezi zixhobo ngokukhawuleza:

• Izixhobo zokuzikhusela: Iiglavu zesikhumba senkomo eziqinileyo ezicandekileyo ezidlula engqinibeni, iiglavu zokhuseleko zepolycarbonate ezinefuthe eliphezulu okanye isikhuselo sobuso esigcweleyo, kunye neN95 okanye isiqingatha semaski esiphefumlayo.
• Ii-agent zokucima umlilo: Iibhokisi ezimbini ukuya kwezine (1 ukuya 2 kilograms / 2 to 4 pounds) of commercial bicarbonate yesodium (baking soda), okanye i-20-litre (5-gallon) emele yesanti eyomileyo yokudlala yamatye.
• Izixhobo zokukhangela oomatshini: Ipoker yentsimbi eqinileyo eqinileyo (ubuncinci i-750 millimeters / 30 intshi ubude), imitha e-1 (3-foot) ubude be-25-millimeter (1-intshi) Shedyuli 40 umbhobho wentsimbi emnyama, iipliyisi zokutshixa (Vise-Grips), kunye nesando esinzima sozipho.
• Izixhobo zokungenisa umoya: Iifeni zebhokisi eziphathwayo zesantya esiphezulu kunye nezihambisi zomoya zomgangatho.

Umgaqo-nkqubo A: Uthintelo lomlilo olukhuselekileyo, olungaqhumiyo¶

1. Ungaze usebenzise amanzi alulwelo: Khumbula ukuba amanzi abetha amalahle ashushu ayanda ukuya kutsho kwi-1,700 ngokuwuphinda-phinda umthamo wawo njengomphunga, ukuvuthela amalahle avuthayo kunye nothuthu kwigumbi.
2. Faka isodiyam bicarbonate: Vula isikhongozeli sesoda yokubhaka uze uyisasaze kakhulu phezu kweenkuni ezivuthayo. Injongo ngqo kwisiseko somlilo apho iinkuni zidibana namalahle. Ubushushu obugqithisileyo bubangela ukuba i-sodium bicarbonate ibole ngokufudumeleyo ibe yi-sodium carbonate, umphunga wamanzi, kunye ne-carbon dioxide:

   Thermal Decomposition:
     2 NaHCO3 + Heat ===> Na2CO3 + H2O + CO2
   

   Igesi exineneyo yekhabhon diokside isusa ioksijini kumphezulu wepetroli, icima amadangatye asebenzayo ngaphakathi kwe30 ukuya kwimizuzwana engama-60 ngaphandle kokudala ukuqhushumba komphunga.
3. Fumisa ngesanti eyomileyo: Ukuba amadangatye ayaqhubeka okanye ukuba iinkuni ezivuthayo zikhulu, galela isanti yokudlala eyomileyo ngokuthe ngqo phezu kweenkuni de yonke ibhedi yamafutha igqunywe ngaphantsi kwe-50-millimeter (2-intshi) yesanti. Isanti enzima inqumla yonke ioksijini esemoyeni ngelixa ifunxa ubushushu obukhazimlayo.
4. Yaba ibhedi yamafutha: Sebenzisa intsimbi yepoker ukwahlula iinkuni ezishiyekileyo, uzityhale zibe mcaba kumgangatho weziko ukuphelisa impendulo yobushushu obubengezelayo phakathi kweendawo ezivuthayo ezikufutshane.

Umgaqo-nkqubo B: Ukukhulula kunye nokuphakamisa isidambisi somqala esibanjiweyo¶

Nje ukuba amadangatye asebenzayo acinezelwe kwaye ibhedi yokugquma igqunywe ngesanti, zama ukukhulula ipleyiti yedamper ukuze uvumele iigesi eziqhumayo ukuba ziphume ngetshimini:

1. Xhobisa iiglavu zokuwelda: Nxiba iiglavu zokuwelda ngesikhumba kunye neglavu ngokuchasene nobushushu obugqithileyo kuma-200 degrees Celsius (392 degrees Fahrenheit).
2. Misa isixhobo sokukroba sentsimbi: Faka ipoker yentsimbi enzima okanye iimitha ezi-1 (unyawo olu-3) umbhobho wentsimbi phantsi komphetho osezantsi wepleyiti exineneyo.
3. Faka amandla ajonge phezulu: Tyhila phezulu ngokuqinileyo. Amandla aqhubekayo aya kucheba kancinane iibhondi ezithambileyo ze-creosote.
4. Zophula iibhondi zekharbhoni ngempembelelo: Ukuba ipleyiti ingumkhenkce, cofa isiphelo esisezantsi sombhobho kabukhali ngehamile ukuze uqhekeze iibhondi zekreosote ezibhuqekayo.
5. Sula ukuvaleka kweshelufu yomsi: Ukuba umsizi owileyo uvalela ipleyiti, itshayele i-poker kwishelufu yomsi ukutyhala umle.
6. Khusela ngepropu yoomatshini: Ungaze uthembe isidambisi manzi esonakeleyo ukuba sihlale sivulekile. Wejisa ipoker yentsimbi okanye umbhobho wentsimbi ngokuthe nkqo phakathi komgangatho weziko kunye nepleyiti yedamper ukuqinisekisa ukukhupha okuqhubekayo.

I-Protocol C: Ukuphinda ucinezele okanye ubambe i-damper yentambo yokutywina phezulu¶

Ukuba indawo yomlilo ine-damper yokutywina ephezulu kwaye intambo yokulawula ivaliwe okanye ihluthiwe:

1. Khangela indawo yokuqhawula intambo: Jonga intambo yentsimbi ephothiweyo engaphakathi kwibhokisi yomlilo. Ukuba intambo ivaliwe kwisibiyeli sodonga lobhedu, bamba isiphelo sentambo kunye neepliers zokutshixa.
2. Tsalela ezantsi ukuze uvule okanye ukhulule: Kwizidambisi manzi ezitywina phezulu ezisemgangathweni, umthombo wophahla ubamba ikepusi ivuliwe, kwaye ukutsalela intambo ezantsi kuyitsala ivale. Nangona kunjalo, kwi-reverse-action top dampers, ukutsalela intambo ezantsi kucinezela intwasahlobo yangaphakathi kwaye ivule i-cap. Jonga indlela osebenza ngayo umenzi othile.
3. Bambesa intambo: Ukuba ukutsalwa kwentambo ezantsi kuyafuneka ukuze ubambe isixhobo sokufudumeza sivuleke, yitsale intambo ezantsi ngokuqinileyo ngeepliers zokutshixa kwaye ubambe iipliers ngokuqinileyo kumphetho ongezantsi wesibiyeli sokuxhoma ibhokisi yomlilo.
4. Qinisekisa idrafti yeflue: Bamba imatshisi elayitiweyo okanye ipensile yomsi kufutshane nomphezulu webhokisi yomlilo. Umsi kufuneka utsale kabukhali phezulu nangaphakathi kwi-chimney flue, eqinisekisa ukuba i-damper cap ivuliwe.

Damper Securing Sequence:
1. Apply upward force with steel pipe to break thermal bind
2. Fracture carbonized creosote using controlled hammer taps on pipe
3. Sweep steel poker across smoke shelf to clear fallen soot mounds
4. Prop plate open mechanically using iron pipe wedged to firebox floor
5. Verify upward convective draft with smoke pencil test

Umgaqo-nkqubo D: Ukukhutshwa koxinzelelo olubi ngaphakathi komsi¶

Ukususa umsi kwindawo yokuhlala kufuna ukulawulwa ngononophelo lokwakha ukugeleza komoya ukuthintela ukungcola okusasazeka kwimigangatho ephezulu okanye kwiindawo zokulala:

1. Beka yedwa igumbi lomlilo: Vala zonke iingcango zangaphakathi ezidibanisa igumbi lendawo yeziko kwiipaseji, izinyuko, kunye namagumbi okulala. Oku kuthintela iinxalenye eziyityhefu kwindawo enye yothintelo.
2. Chonga icala lomoya okhoyo: Jonga ngaphandle ukujonga icala lomoya. Ukuba umoya uvuthuza ngokuthe ngqo kwiifestile zegumbi leziko, ukuzivula kuya kucinezela igumbi, ukunyanzela umsi kwiingcango zeminyango kunye nendlu yonke.
3. Vula iifestile ze-leeward zokukhupha: Vula iifestile kwicala elinomoya osezantsi (ekwi-leeward) legumbi lendawo eziko. Uxinzelelo lomoya ongalunganga ngokwendalo lukhula kudonga lwangaphandle lwe-leeward lwesakhiwo, lutsala umoya ngaphandle.
4. Seta umsi womtshini: Beka ifeni yebhokisi yombane kwifestile evulekileyo yeleeward ejonge ngaphandle ukuya ngaphandle. Vala izithuba phakathi kwesakhelo sefeni kunye nefestile yefestile ngekhadibhodi okanye iitawuli. Jika ifeni kwisantya esiphezulu.
5. Ngqobhoza ifestile yonikezelo oluya ngasemoyeni: Uqhekeze ifestile encinci evule iimilimitha ezingama-50 (ii-intshi ezi-2) kwelinye icala legumbi ukuze ubonelele ngomoya ococekileyo wokuzihombisa, udale impepho evuthuzayo ethe tye etshayela umsi ngaphandle kwefeni yokukhupha umoya.

Ukuthelekiswa kwee-arhente zokucima umlilo kunye noqhagamshelwano lomatshini¶

Imimiselo yekhowudi yokwakha, ukukhutshwa kwetshimini, kunye nemigangatho yomthetho¶

Ulwakhiwo lweziko, iinkcukacha zokudambisa, kunye neemfuno zedrafti zetshimini zilawulwa ngokungqongqo ziikhowudi zokhuseleko lomlilo zikamasipala nelizwe:

• i-NFPA 211: Ifuna iindawo zokubasa iimasonry ukuba zibenedamper esebenzayo eyenziwe ngezinto ezingatshiyo (intsimbi etyhidiweyo okanye ubuncinane intsimbi ye-12-gauge), esebenza ukusuka kwigumbi kwaye ebonisa isimo esivulekileyo okanye esivaliweyo.
• IKhowudi yokuHlala yaMazwe ngaMazwe (iCandelo le-IRC R1001.5): Izigunyaziso ezizidambisi manzi zihlala ubuncinane kwiimilimitha ezingama-200 (ii-intshi ezisi-8) ngaphezu kwendawo yokuvula iziko, kunye nendawo yokuvula ehambelana ne-flue liner.
• IKhowudi yoMlilo yaMazwe ngaMazwe (IFC Isahluko sesi-6): Ilawula ugcino lwamafutha aqinileyo, inqanda ukusetyenziswa kweziko xa ikreosote ingaphezu kweemilimitha ezi-3 (⅛ intshi) okanye xa izidambisi zibophene.
• I-Uniform Mechanical Code (UMC Isahluko sesi-9): Iinkcukacha ngokuvuleka komoya ovuthayo kunye neemilimitha ezingama-50 (ii-intshi ezi-2) zokususwa kwefreyim kwiitshimini zangaphakathi.
• Umgangatho waseBritani we-BS EN 15287-1: Ilawula uyilo lwetshimney flue, efuna ubuncinci be-12-pascal Draft thresholds.
• iMigangatho yase-Australian AS/NZS 2918: Ilawula izifudumezi zamafutha aqinileyo, ucociso lweflue, kunye nemida yokukhupha kuyo yonke i-Australia neNew Zealand.

Imibuzo ebuzwa qho¶

Kutheni ndingagaleli amanzi eziko xa kukho umsi kwigumbi lam lokuhlala?¶

Ungaze ugalele amanzi kwindawo yomlilo esebenzayo ngesidambisi manzi esixineneyo kuba amanzi ayanda ukuya kutsho kwi-1,700 ngokuphinda-phinda umthamo wawo wolwelo njengomphunga kwiimilliseconds zokudibana nezigodo ezivuthayo kunye nezitena zomlilo ezishushu kakhulu. Olu gqabhuko-dubulo lomphunga ngoko nangoko ludubula amanzi abilayo, amalahle avuthayo, kunye nomsizi ophuma emoyeni ngqo ngaphandle kwebhokisi yomlilo kunye negumbi lakho lokuhlala. Umothuko ogqithisileyo wamanzi abandayo xa ebetha intsimbi etshiswe kakhulu kunye nezitena ezilahlayo ziya kuqhekeza amalungu odaka lwezitena zomlilo, kwaphule isakhelo sokudambisa isidambisi sentsimbi, kwaye kubeke esichengeni ngokusisigxina ukubanjwa komlilo wetshimini.

Yintoni ebangela ukuba isidambisi somqala sivaleke xa umlilo uvutha?¶

Ijem yokudambisa umqala ivale phakathi ekutshisweni ngenxa ye-thermal warping okanye i-creosote glaze ebophayo. Xa umlilo utshisa ngokugqithisileyo, i-cast-iron okanye i-steel-steel damper plate ikhula ngokukhawuleza kunesakhelo se-masonry esijikelezileyo, ibangela ukuba ipleyiti iphume kwinqwelomoya kwaye ibophe ngokuqinileyo kwiingoma ezisecaleni. Inqanaba Lesithathu itar ebhakwe kwipivot pin nayo inokunyibilikisa, ikharbhonize, kwaye iqine njengesamente, okanye imfumba yomsizi oye waqokelelwa kwishelufa yomsi ethe tyaba emva kwedamper inokudilika endleleni, ivale ipleyiti ngoomatshini.

Ndingazi njani ukuba itshimini yam yokutywina ephezulu ivalekile?¶

Unokwazi ukuchonga isidambisi setshimney esitywiniweyo ngokujonga intambo ephothiweyo yentsimbi engenasici ngaphakathi kwibhokisi yomlilo kunye nokuziphatha kwangoko komsi. Ukuba intambo ijinga ngokupheleleyo kunye noxinzelelo lwasentwasahlobo oluthi zero, isipringi esifakwe eluphahleni asiphumelelanga, intambo igqabhukile, okanye isibiyeli siphumile, sivumela umphezulu onzima ukuba uvaleke phezu kweflue. Kwimizuzwana nje yokuvalwa komnqwazi, umsi uya kuphumela ngaphandle ungene kwigumbi kunye nobubanzi bonke bendawo yomlilo, kunye nethotshi ejonge emqaleni iyakutyhila ukukhanya kwemini nge-flue.

Ngaba kukhuselekile ukushiya isikrini sebhokisi yomlilo sivulekile ngelixa ugquma indawo yomlilo exineneyo?¶

Ungaze ushiye ibhokisi yomlilo ivuleke ngokupheleleyo ngelixa ulawula umlilo oxineneyo kwiziko; gcina umnatha wentsimbi enzima isikrini sentlantsi okanye iingcango zeglasi zivaliwe kangangoko. Njengoko umlilo ulamba ioksijini ngesidambisi esivaliweyo, iipokotho zerhasi yomthi ongatshiyo zinokuvutha rhoqo, zibangele iipopu ezincinci zoxinzelelo ezikhupha amaqhekeza omthi avuthayo kunye namalahle ashushu kwigumbi. Ukuba iziko lakho alinazo iingcango zeglasi, tsala umnatha wocingo olucikizekileyo ikhethini uvale ngokupheleleyo phakathi kwesoda yokubhaka okanye isanti ukukhusela umgangatho wakho ekuvutheni komlilo.
