Qhov kub ntawm lub tshuab hluav taws xob yog qhov kub npaum li cas rau cov roj cua sov

Siv cov roj hloov hluav taws xob los ua cov khoom siv hluav taws xob, cov cua sov yog rhuab thiab tsis ncaj qha xa mus. Vim tias cov cua sov tsis sib xws, tsis tshua muaj kev tswj xyuas qhov kub siab, kev hloov hluav taws xob zoo, txuag hluav taws xob, thiab kev thauj mus los yooj yim thiab kev ua haujlwm, cov roj hloov hluav taws xob hauv hluav taws xob hluav taws xob feem ntau suav nrog cov roj hluav taws xob hloov hluav taws xob thiab cov roj hluav taws xob hloov hluav taws xob.
Mineral tshav kub roj feem ntau yog siv rau hluav taws xob cua sov nyob rau hauv thermal roj furnaces, thiab nws cov kev khiav hauj lwm kub tsis tau tshaj 300 degree. Txawm li cas los xij, hom roj hloov hluav taws xob no muaj cov qauv tsis ruaj khov ntawm qhov kub thiab txias, ua rau nws nyuaj los xyuas kom meej lub neej kev pab cuam ntawm lub tshav kub hloov roj boiler system thiab cov roj hloov hluav taws xob. Feem ntau cov khoom siv hluav taws xob hloov hluav taws xob hloov hluav taws xob yog siv ntawm qhov kub txog li 350 degree. Qhov kub ntawm lub tshav kub conduction roj cua sov rauv mus txog 350 degree.
Qhov kub ntau dhau yuav ua rau lub thermal polymerization thiab oxidation cov tshuaj tiv thaiv ntawm cov roj hloov hluav taws xob, tsim coke, uas cuam tshuam rau lub neej kev pab cuam ntawm cov roj hloov hluav taws xob. Raws li qhov kub thiab txias nce, thermal polymerization thiab oxidation cov tshuaj tiv thaiv yog txhim kho, ua rau lub cim ntawm coke. Qhov tsim kub ntawm thermal conductive hluav taws xob cua sov roj rauv yog 350 degree, thiab nitrogen gas yuav tsum tau ntxiv kom txo tau cov pa roj carbon deposition nyob rau hauv lub slag.
Thermal roj rauv hluav taws xob rhaub
Ua ntej tshaj tawm cov thermal conductivity cua sov, qhov kub ntawm thermal conductivity roj ntawm lub lag luam tsis tshaj 350 degree, feem ntau nyob rau hauv cov qauv xws li 250 degree, 300 degree, thiab 350 degree. Lub tshuab hluav taws xob cua sov siv hluav taws xob hloov hluav taws xob ua hluav taws xob hloov hluav taws xob nruab nrab. Nyob rau hauv xyoo tas los no, vim yog cov yam ntxwv ntawm cov cua sov tsis sib xws, kev tswj qhov kub thiab txias, tsis tshua muaj zog siab, zoo hloov hluav taws xob zoo, txuag hluav taws xob, kev thauj mus los yooj yim thiab lwm yam, cov roj hluav taws xob hloov hluav taws xob tau siv dav hauv ntau lub sijhawm.
Cov roj hloov hluav taws xob siv hluav taws xob siv hluav taws xob feem ntau yog muab faib ua cov roj hluav taws xob hloov hluav taws xob thiab hluav taws xob hloov hluav taws xob. Qhov kub ntawm lub thermal roj hluav taws xob rhaub tau tam sim no mus txog 350 degree. Qhov kub ntau dhau yuav ua rau lub thermal polymerization thiab oxidation cov tshuaj tiv thaiv ntawm cov roj hloov hluav taws xob, tsim coke, uas cuam tshuam rau lub neej kev pab cuam ntawm cov roj hloov hluav taws xob. Raws li qhov kub thiab txias nce, thermal polymerization thiab oxidation cov tshuaj tiv thaiv yog txhim kho, ua rau lub cim ntawm coke.
Ntawm qhov ntsuas kub ntawm 350 degree, nws tseem yuav tsum tau kaw lub thermal roj hluav taws xob rhaub kom txo tau cov pa roj carbon monoxide. Rau kev tsim cov roj hluav taws xob hluav taws xob cua sov, nws yog ib qho tsim nyog yuav tsum xav txog qhov ua tau zoo ntawm qhov kub thiab txias ntawm flanges, li qub, cov kav dej sib txawv, cov twj tso kua mis, thiab lwm yam. Xaiv qhov kub-kub nres valve thiab cov roj hloov hluav taws xob hloov hluav taws xob uas tuaj yeem tiv taus qhov kub thiab txias ntawm 400 degree kom ntseeg tau tias muaj kev nyab xeeb ntawm cov roj hluav taws xob hloov hluav taws xob.
