Txhawm rau kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm cov txheej txheem cov kav dej hauv cov txheej txheem tsim khoom, feem ntau ntawm lawv yuav tsum tau siv thermal rwb thaiv tsev (kub khaws cia) ntsuas. Txawm li cas los xij, qhov poob ntawm qhov hluav taws kub tsis tuaj yeem zam tau thaum lub sijhawm khaws cia thiab kev sib kis ntawm cov txheej txheem nruab nrab. Thaum tshav kub kub dissipation txhais tau hais tias qhov txo qis hauv qhov kub ntawm qhov nruab nrab hauv cov khoom siv thiab cov kav dej. Yog li, dab tsi yog yam uas cuam tshuam rau kev poob cua sov hauv hluav taws xob cua sov tracing engineering?
Ua ntej, kev saib xyuas qhov kub thiab txias ntawm lub raj xa hluav taws xob hluav taws xob cua sov yog qhov tseem ceeb heev rau kev suav cov cua sov, yog li nws yog qhov tsim nyog xaiv. Yog tias qhov ntsuas kub qis dhau lawm, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov ntsuas kub ntawm qhov nruab nrab; Piv txwv li, kev tswj xyuas qhov kub thiab txias siab tshaj qhov yuav tsum tau ua kom sov yuav ua rau lub zog khib nyiab, uas yuav ntxiv cov nqi ntxiv.
Qhov thib ob, hom nruab nrab
Cov cua kub tshwj xeeb ntawm qhov nruab nrab (roj, dej kub, roj, nkev, thiab lwm yam) yog qhov sib txawv, thiab cov ntsiab lus ntawm nws cov nqi calorific yuav txawv, thiab qhov kub poob yuav cuam tshuam rau kev siv tiag tiag.
3. Qhov loj ntawm cov khoom siv lossis cov kav dej
Piv txwv li: txoj kab uas hla ntawm cov yeeb nkab, txoj kab uas hla ntawm lub tank, qhov loj dua qhov loj, qhov kub ntau poob.
Plaub, qhov kev hloov ntawm ambient kub muaj kev cuam tshuam ntau dua rau qhov poob ntawm nruab nrab kub;
Qhov qis dua qhov kub thiab txias, qhov kub poob ntau dua ntawm cov hluav taws xob tracing system ntawm tib qhov kub thiab txias. Yuav kom nyob rau sab nyab xeeb, nws tsim nyog kom paub meej tias qhov tsawg kawg nkaus ambient kub tau txais. Tsis tas li ntawd, cua ceev kuj muaj feem cuam tshuam rau kev poob cua sov, thiab qhov cua nrawm dua, qhov kub poob ntau dua.

5. Qhov siab tshaj plaws nqa kub ntawm hluav taws xob tracing
Qee lub sij hawm qhov kub thiab txias yuav tsum tau los ntawm cov khoom siv tsis yog siab, tab sis muaj ib qho kev tshem tawm tam sim ntawd, uas yuav tsum muaj qhov kub thiab txias ntawm cov khoom siv hluav taws xob cua sov kom siab.
Piv txwv li, cov hluav taws xob cua sov daim ntawv thov ntawm desulfurization pipeline nyob rau hauv lub fais fab nroj tsuag, los ntawm cov chav purging, lub zoo tib yam hluav taws xob hluav taws xob tshav kub qhov kub kuj tsis tuaj yeem ncav cuag, thiab nws yog ib qho tsim nyog yuav tau xaiv cov khoom siv hluav taws xob thaum tshav kub kub tracing thiab rwb thaiv tsev cov khoom nrog kub tsis kam.
6. Cov khoom siv thermal rwb thaiv tsev
Kev cuam tshuam ntawm cov thickness ntawm cov khoom siv rwb thaiv tsev ntawm cov nyhuv ntawm thermal rwb thaiv tsev kuj tseem loj heev, thiab cov thermal conductivity ntawm thermal rwb thaiv tsev cov khoom ntawm cov khoom sib txawv tsis zoo ib yam, thiab cov thermal rwb thaiv tsev cov nyhuv txawv heev. Qee lub sij hawm, cov kev xav tau ntawm cov cua sov tuaj yeem ua tau raws li tsuas yog hloov hom lossis tuab ntawm cov khoom siv rwb thaiv tsev yam tsis tau hloov cov khoom siv hluav taws xob, uas tuaj yeem txuag hluav taws xob thiab txo cov nqi.
