Kev ua haujlwm ntawm kev txhim kho fins kuj tuaj yeem ua piv txwv nrog cov piv txwv zoo li hauv qab no: ntawm qhov nkag thiab tawm ntawm qhov chaw nres nkoj ciam teb, xav tias qhov chaw nres nkoj ntawm Party A muaj kaum qhov chaw kuaj xyuas, uas tuaj yeem tso tawm 5000 tus neeg hauv ib teev, thaum lub chaw nres nkoj ntawm Party B tsuas muaj ib daim pib kuaj xyuas qhov chaw nres nkoj, thiab cov txheej txheem qeeb heev, tsuas yog 50 tus neeg tuaj yeem tso tawm ib teev. Nyob rau hauv txoj kev no, tus thib ob tog dhau los ua lub hwj chim rau cov neeg caij tsheb kom tshem tawm kev lis kev cai, tiv thaiv thawj tog "muaj peev xwm" los ntawm kev siv tag nrho. Txoj hauv kev zoo tshaj plaws los ua kom qhov kev tshem tawm yog qhib ob peb lub chaw soj ntsuam ntawm sab ntawm Party B. Qhov no yog tib txoj cai raws li kev ntxiv fins. Tom qab nkag siab txog lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm cov raj finned, thaum xaiv cov raj finned, muaj ob peb lub hauv paus ntsiab lus: (1) Yog tias cov cua sov hloov coefficients ntawm ob sab ntawm lub raj sib txawv heev, fins yuav tsum tau nruab rau sab nrog qis dua cov coefficients. Piv txwv 1: Boiler economizer, nrog cov dej ntws hauv cov yeeb nkab thiab cov pa luam yeeb ntws tawm sab nraud, cov fins yuav tsum tau siv rau ntawm cov pa luam yeeb. Piv txwv 2: Cua txias, nrog cov kua ntws hauv lub raj thiab cua ntws tawm sab nraum lub raj, cov fins yuav tsum tau ntxiv rau ntawm huab cua sab. Piv txwv 3: Hauv lub tshuab hluav taws xob, muaj dej kub hauv lub raj, thiab cov pa luam yeeb ntws tawm sab nraud ntawm lub raj. Fins yuav tsum tau ntxiv rau sab haus luam yeeb. Nws yuav tsum tau muab sau tseg tias thaum lub sij hawm tsim, sab nrog ib tug tsawg tshav kub hloov coefficient yuav tsum tau muab tso rau sab nraum lub raj kom ntau li ntau tau los pab txhawb lub installation ntawm fins. (2) Yog hais tias lub tshav kub hloov pauv coefficient ntawm ob sab ntawm cov yeeb nkab yog me me, txhawm rau txhim kho cov cua sov hloov, cov fins yuav tsum tau nruab rau ntawm ob sab ib txhij. Yog tias muaj teeb meem ntawm cov txheej txheem, fins tuaj yeem raug tshem tawm ntawm ob sab. Nyob rau hauv rooj plaub no, ntxiv fins nkaus xwb ntawm ib sab yuav tsis muaj qhov cuam tshuam loj rau kev hloov cov cua sov. Piv txwv 1: Traditional tubular cua preheaters siv cua hauv cov kav dej thiab cov pa luam yeeb sab nraum cov kav dej. Vim tias nws yog cov pa roj rau cov pa hluav taws xob hloov hluav taws xob, cov hluav taws xob hloov hluav taws xob ntawm ob sab qis heev, thiab nws nyuaj rau ntxiv fins hauv lub raj, yog li peb yuav tsum siv tag nrho cov raj. Piv txwv 2: Lub tshuab cua sov cua sov, txawm hais tias tseem muaj cua sov los ntawm cov pa roj, tuaj yeem yooj yim siv cov raj finned ntawm ob qho tib si flue roj thiab cua sab vim qhov ntws ntawm cov roj flue thiab cua sab nraum lub raj, ua rau kom kub hloov mus. (3) Yog hais tias lub tshav kub hloov coefficients ntawm ob sab ntawm lub raj yog loj, nws tsis yog yuav tsum tau siv finned hlab. Piv txwv 1: Thaum siv cov dej kub los ua kom sov cov dej txias hauv dej / dej kub exchanger, yog tias cov cua sov hloov coefficient ntawm ob sab siab txaus, tsis tas yuav siv cov raj finned. Tab sis txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yuav tsum tau tshem tawm cov cua sov, cov kav dej threaded lossis cov kav dej corrugated tuaj yeem siv los hloov cov kav dej. Piv txwv 2: Lub condenser ntawm ib lub tshuab fais fab yog ib qho condensation ntawm dej vapor sab nraum cov yeeb nkab, thaum dej ntws hauv cov yeeb nkab. Lub tshav kub hloov coefficients ntawm ob sab yog siab heev, thiab feem ntau, finned tubes tsis xav tau.
