Raws li cov roj combustible, cov pa roj ntsha tuaj yeem hlawv ua ke nrog huab cua kom tso cov cua sov ntau hauv cov xwm txheej ib txwm muaj. Cov txheej txheem ntawm cov pa roj combustion ib txwm yog qhov ruaj khov thiab tswj tau. Txawm li cas los xij, yog tias nyob rau hauv ib qho chaw uas tsis muaj huab cua ncig, tom qab cov pa roj ntsha tuaj, nws yuav sib sau ua ke hauv chav. Thaum lub concentration ntawm natural gas ntau tshaj 5%, thaum nws ntsib ib tug qhib nplaim taws los yog ib tug hluav taws xob spark, lub ntuj gas yuav tam sim ntawd hlawv uncontrollably thiab tsausmuag, thiab ces lub ntim expansion ua rau tawg.
Natural gas nws tus kheej tsis muaj xim thiab tsis muaj ntxhiab. Txhawm rau ua kom tib neeg paub txog cov pa roj carbon monoxide, hydrogen sulfide lossis tshuaj tsw qab uas muaj mercapto pawg tau ntxiv rau cov roj ntuj rau kev siv hauv tsev. Yog tias muaj cov pa paug, peb yuav hnov qab ib yam li cov qe lwj.
Thaum cov pa roj paug tawm, nws feem ntau muaj cov roj hauv qab no:
Methane (CH4): Methane yog qhov tseem ceeb ntawm cov pa roj carbon monoxide thiab feem ntau suav rau feem ntau ntawm cov nkev ntuj, yog li nws ua rau cov pa taws tso tawm. Nws yog cov tsis muaj xim, tsis muaj ntxhiab, tsis muaj tshuaj lom, tab sis tuaj yeem tawg hauv qhov siab.
Ethane (C2H6): Ethane feem ntau yog ib qho me me ntawm cov pa roj carbon monoxide, tab sis kuj tso tawm nrog methane. Nws yog ib qho hluav taws kub uas tuaj yeem ua rau hluav taws kub lossis tawg.
Nitrogen (N2): Nitrogen yog ib qho ntawm cov khoom tseem ceeb ntawm huab cua thiab feem ntau tso tawm nrog cov pa roj. Nitrogen nws tus kheej tsis yog nplaim taws, tab sis nws tuaj yeem txo cov pa oxygen, yog li txo qhov kev pheej hmoo ntawm hluav taws lossis tawg.
Cov pa roj carbon monoxide (CO): Cov pa roj carbon monoxide yog cov pa roj carbon monoxide uas yuav tsim tau thaum cov pa roj carbon monoxide hlawv tsis tiav. Nws yog cov roj tsis muaj xim, tsis muaj ntxhiab tsw, tab sis nqus tau cov pa roj carbon monoxide siab tuaj yeem ua rau muaj kev phom sij lossis ua rau tib neeg lub cev tuag taus.
Hydrogen sulfide (H2S): Hydrogen sulfide yog cov pa roj lom uas feem ntau pom muaj nyob hauv cov khoom siv roj ntsha. Kev nqus tau los yog raug rau qhov siab ntawm hydrogen sulfide tuaj yeem ua rau muaj kev phom sij loj rau tib neeg lub cev, txawm tias tuag taus.
Cov kev phom sij tseem ceeb ntawm cov pa roj carbon monoxide tawm los ntawm qhov tshwm sim ntawm methane thiab toxicity ntawm cov pa phem xws li carbon monoxide thiab hydrogen sulfide, yog li kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum cuam tshuam nrog cov pa roj carbon monoxide.
Yog tias peb nyob deb ntawm qhov chaw nkev, lossis yog tias peb tsaug zog, peb yuav tsis hnov ntxhiab tsw ntxhiab. Rau kev nyab xeeb vim li cas, koj tuaj yeem nruab lub tswb hluav taws xob lossisCombustible Gas Leak Detectorhauv chav ua noj.
Kev xau ntawm cov pa roj ntsha feem ntau tshwm sim ntawm qhov sib cuam tshuam, thiab qhov xwm txheej ntawm cov khoom siv roj hauv tsev yuav tsum tau kuaj xyuas tsis tu ncua. Cov khoom siv hluav taws xob qub yuav tsum tau hloov lub sijhawm los tiv thaiv cov kav dej thiab kev sib txuas los ntawm kev laus, thiab lub tuam txhab roj kuj tseem yuav xyuas cov raj xa hluav taws xob tsis tu ncua.
