combustion

combustion tuaj yeem muab faib ua nplaim hluav taws kub thiab tsis muaj nplaim taws. Qhov tshwm sim thiab kev loj hlob ntawm combustion yuav tsum muaj peb yam tseem ceeb: combustibles, oxidizers (combustion promoters), thiab kub (kub qhov chaw). Cov xwm txheej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm kev tiv thaiv hluav taws thiab kev tswj hwm, uas feem ntau siv cov cuab yeej xws li tua hluav taws tua hluav taws.

Cov tua hluav taws tua hluav taws, tseem hu ua hluav taws saib xyuas, yog cov khoom siv hluav taws xob muaj zog uas tsim cov dej ntim ntau hauv cov kwj deg. Cov cannons no feem ntau ntsia rau ntawm cov tsheb tua hluav taws lossis lwm lub tsheb tua hluav taws thiab muab cov cuab yeej tseem ceeb hauv kev tua cov nplaim taws los ntawm kev nyab xeeb.

Thaum siv afirefighting dej cannon, Nws yog ib qho tseem ceeb kom nkag siab txog cov xwm txheej tsim nyog rau kev sib xyaw. Nyob rau hauv lub xub ntiag ntawm ib tug combustible khoom, oxygen thiab tshav kub, combustion yuav sai sai tig mus rau hauv ib tug raging inferno, ua rau nws kim heev kev puas tsuaj thiab poob ntawm lub neej. Los ntawm kev siv cov phom tua hluav taws tua hluav taws los tua cov nplaim hluav taws, qhov kub thiab txias (qhov hluav taws xob hluav taws xob) txo qis, thiab cov khoom siv hluav taws xob tsis muaj oxygen, tua hluav taws zoo.

Tsis tas li ntawd, thaum cuam tshuam nrog cov kua dej ua paug xws li roj av lossis cov khoom siv tshuaj, nws yog ib qho tseem ceeb uas yuav tsum tau siv hom tshwj xeeb ntawm cov phom tua hluav taws. Cov cannons no tau nruab nrog ua npuas ncauj lossis gel nozzles uas sib tov dej nrog cov nplaim hluav taws kub hnyiab, tsim kom muaj cov khoom tuab tuab, uas ua rau cov nplaim taws zoo.

Hauv kev xaus, kev tiv thaiv kom zoo thiab tswj cov hluav taws kub nyhiab yuav tsum muaj kev nkag siab txog cov xwm txheej tseem ceeb uas ua rau muaj kev kub ntxhov. Nrog rau kev siv cov cuab yeej xws li tua hluav taws tua hluav taws, peb tuaj yeem ua cov kauj ruam tseem ceeb los tiv thaiv hluav taws thiab tiv thaiv lub neej thiab khoom.
