Vim li cas Natural Gas tsw zoo li Rotten Qe thaum hlawv?
Hauv phau ntawv qhia no: Cov lus teb ncaj qha, technically raug teb rau "vim li cas cov pa roj carbon monoxide tsw zoo li cov qe lwj thaum hlawv?" - npog cov roj yam dab tsi hauv nws daim ntawv ntshiab, mercaptan odorant ntxiv rau kev nyab xeeb, dab tsi tshwm sim thaum roj hlawv, vim li cas koj thiaj hnov "roj qe" thaum los yog tom qab hlawv (thiab vim li cas feem ntau yog ib qho kev ceeb toom), chemistry ntawm mercaptan combustion, qhov sib txawv ntawm lub teeb ib txwm {{1}tawm puff thiab cov lus nug txaus ntshai tsis tiav, feem ntau cov lus nug tsis tiav kub.
Vim li cas Natural Gas tsw zoo li Rotten Qe thaum hlawv? - Teb ceev
Nov yog qhov tseeb tseem ceeb: cov pa roj ntshiab tsis hnov tsw zoo li cov qe lwj thaum nws hlawv kom raug.Natural gas yog methane (CH₄) - odorless. Cov ntxhiab tsw "rotten egg" yog los ntawm mercaptan, sulfur -raws li odorant ntxiv kom cov xau tuaj yeem ntes tau. Thaum cov roj kub hnyiab nrog cov nplaim hluav taws xiav (ua kom tiav), mercaptan raug hlawv ib yam nkaus, thiab koj yuav tsum tsis txhob hnov qab cov qe lwj.
Yog tias koj hnov cov qe lwj thaum lossis tom qab lub tshuab hluav taws xob khiav, nws feem ntau txhais tau tias tsis tiav combustion - unburned, odorised gas yog khiav tawm vim lub burner tsis hlawv cov pa tag nrho.Qhov ntawd yog lub cim ceeb toom: nws taw qhia rau lub qhov cub qias neeg lossis tsis raug kho, qhov cua tsis zoo, lossis lub teeb daj / txiv kab ntxwv (tsis tiav) nplaim taws - thiab qhov hluav taws kub tsis tiav kuj ua rau carbon monoxide (CO). Ib qho luv luv puff ntawm tsis hnov tsw thaum lub teeb pom kev zoo yog qhov qub; tsis muaj ntxhiab tsw thaum hlawv tsis yog.
