Thaum hav zoov raug kev txom nyem los ntawm hluav taws, qhov teeb meem ncaj qha tshaj plaws yog hlawv lossis hlawv ntoo. Ntawm ib sab, hav zoov poob qis, ntawm qhov tod tes, kev loj hlob ntawm hav zoov tau cuam tshuam loj heev.Forests yog cov peev txheej txuas ntxiv nrog lub voj voog loj hlob ntev, thiab Nws yuav siv sij hawm ntev rau lawv kom rov zoo dua tom qab hluav taws.Tshwj xeeb tshaj yog tom qab kev kub ntxhov loj hauv hav zoov, hav zoov nyuaj rau rov qab los thiab feem ntau hloov los ntawm cov hav zoov uas tsis muaj kev loj hlob los yog cov nroj tsuag. ua tsis muaj av los yog liab qab.
Tag nrho cov organic teeb meem hauv hav zoov, xws li ntoo, tsob ntoo, nyom, mosses, lichens, nplooj tuag, humus, thiab peat, yog combustible.Ntawm lawv, flaming combustible, tseem hu ua qhib hluav taws, muaj peev xwm volatilize combustible gas los tsim nplaim, accounting rau 85 ~ 90% ntawm tag nrho cov hav zoov combustible.Nws yog yus muaj los ntawm kev ceev kis ceev, loj burning cheeb tsam, thiab kev noj ntawm nws tus kheej tshav kub xwb account rau 2 ~ 8% ntawm tag nrho cov cua sov.
Flameless burning combustible tseem hu ua hluav taws tsaus, tsis tuaj yeem decompose txaus combustible gas, tsis muaj nplaim taws, xws li peat, rotten ntoo, accounting rau 6-10% ntawm tag nrho cov hav zoov combustible, nws cov yam ntxwv yog qeeb kis ceev, ntev ntev, noj ntawm lawv tus kheej cov cua sov, xws li peat tuaj yeem haus 50% ntawm nws cov cua sov tag nrho, nyob rau hauv cov xwm txheej ntub dej tseem tuaj yeem hlawv.
Ib kilogram ntawm ntoo siv 32 mus rau 40 cubic meters ntawm huab cua (06 mus rau 0.8 cubic meters ntawm cov pa ntshiab), yog li ntawd, hav zoov hlawv yuav tsum muaj oxygen txaus rau qhov chaw.Nyob rau hauv cov pa oxygen nyob rau hauv cov huab cua yog hais txog 21%. huab cua txo mus rau 14 mus rau 18 feem pua, combustion nres.
