Cov khoom siv xws li cam khwb cia hlau tau paub ntev ntev thiab tau dav heev hauv kev siv hauv tsev thiab kev lag luam. Rau kev siv hauv tsev, lauj kaub tais diav, lauj kaub thiab lwm yam khoom siv hauv tsev yog tsim los ntawm cov khoom siv zoo li no. Nyob rau hauv ancient sij hawm, peb pog koob yawg koob txawm siv hnyav hlau rhuab nrog coals rau hlau ntau hom ntaub linen. Hauv kev lag luam, cov khoom siv no kuj tau siv dav thiab siv rau kev tsim cov cua sov boilers, ntau hom kaus mom thiab lwm yam khoom siv rau kev tsim kho thiab kev lag luam.
Cov khoom lag luam zoo li lub kaus mom hlau yog qhov tsim nyog hauv lub neej niaj hnub hauv nroog. Nws yog siv hauv cov kav dej phwj tuaj, xov tooj thiab cua sov hauv nroog.
Cov dej phwj tuaj cam khwb cia hlau ntawm qhov dej yog siv los kaw cov kab noj hniav ntawm kev sib txuas nrog cov dej phwj tuaj. Raws li txoj cai, cov khoom no tau siv dav hauv nroog ib puag ncig. Tab sis lawv kuj tuaj yeem siv los npog cov dej phwj ntiag tug, piv txwv li, hauv tsev nyob rau lub caij ntuj sov lossis hauv cov tsev nyob hauv lub tebchaws rau qhov chaw nyob mus tas li. Hatches yog tsim nyog rau kev ua haujlwm zoo ntawm lub nroog cov kav dej. Lub qab nthab ruaj khov muab kev nyab xeeb rau tib neeg thiab tsheb hauv ib lub nroog, khov khokaw lub qhov. Lub cam khwb cia hlau hatch yog tsim raws li cov cai thiab cov qauv ntawm GOST. Rau kev tsim cov khoom lag luam, grey cam khwb cia hlau yog siv, uas yog cov khoom siv ruaj khov rau kev ua haujlwm ntev hauv ntau yam kev nyab xeeb. Txhua lub kaus mom tau muab faib ua ob hom: lub teeb thiab hnyav.
Raws li nws paub meej los ntawm cov saum toj no, cov khoom no yuav siv tau ntev. Tseem tsis tau hloov.
Muaj cov xwm txheej tshwj xeeb raws li nws pom zoo kom siv hom khoom no. Lub cam khwb cia hlau hatch yuav tsum tau ua nyob rau hauv nruj raws li cov loads ntawm txoj kev, qhov twg nws yuav nyob. Rau txoj kev uas muaj kev siv tsheb ntau, nws raug nquahu kom nruab cov khoom tseem ceeb tshwj xeeb uas tsim los rau cov hom phiaj no nrog kev ua haujlwm ntawm 25 tf. Tsis tas li ntawd nyob rau hauv cov ntaub ntawv no, hatches nrog ib tug load ntawm 40 tf yuav siv tau. Rau kev siv ntawm cov nyom lossis cov neeg taug kev taug kev, cov khoom siv sib xyaw nrog kev ua haujlwm ntawm 3 tf yog siv. Nyob rau hauv txoj kev hauv nroog nrog qhov nruab nrab ntawm qhov congestion, hatches rau 15 tf tuaj yeem ntsia tau. Raws li cov cim thiab qhov hnyav, cov cam khwb cia hlau hatch muaj qhov hnyav sib txawv, thiab, tau kawg, qhov no cuam tshuam rau nws cov nqi.
Txhua pawg ntawm cov khoom raug sim ua raws li GOST cov qauv. Kev tswj hwm yog ua los ntawm kev ua piv txwv los ntawm batch ntawm qee cov ntawv luam. Yog li, cov khoom raug kuaj los ntawm kev ntsuas qhov kawg load, uas yog nqa tawm ntawm ahydraulic xovxwm hauv chav kuaj. Nyob rau hauv rooj plaub ntawm kev ua pov thawj tiav, cov ntaub ntawv ua raws cai thiab kev ruaj ntseg raug muab. Txhua batch ntawm cov khoom yuav tsum tau nrog ib txheej ntawm cov ntaub ntawv uas paub meej tias ua raws li GOST.
