Hauv kev tsim khoom lag luam, plhaub - thiab - raj kub exchangers yog dav siv cov khoom siv hluav taws xob sib pauv. Piv nrog rau lwm hom kev sib hloov hluav taws xob tsis ncaj, lawv muab qhov chaw hloov hluav taws xob loj dua hauv ib chav tsev ntim thiab muaj qhov zoo dua qhov hloov hluav taws xob. Cov ntsiab lus hauv qab no yuav tsum raug sau tseg thaum lub plhaub ua haujlwm-thiab- raj kub exchangers:
(1) Kev ua haujlwm pib yuav tsum tau qeeb, nrog rau preheating thiab maj mam nce kub;
(2) Kev ua kom zoo preheating ntawm lub siab txo valve thiab kev hloov kho tom qab ua haujlwm yog qhov tseem ceeb;
(3) Thaum pib lub tsev, qhov txias - sab valve yuav tsum qhib ua ntej, thiab qhov kub - sab valve qhib tsuas yog tom qab stabilization; Thaum kaw, qhov kub - sab valve yuav tsum raug kaw ua ntej, tom qab ntawd txias - sab valve;
(4) Tom qab ua haujlwm li qub, kaw lub viav vias valve ntawm chav dej -dej tshav kub exchanger ntws condensate, thiab cov dej condensate yuav muab tso rau hauv ib txwm ua haujlwm. Yog tias qhov ntsuas kub ntawm qhov ntsuas kub tsawg dhau, xws li qis dua 50 degree, lub viav vias valve tuaj yeem qhib. Yog tias qhov ntsuas kub ntawm qhov ntsuas kub siab dhau lawm, xws li siab dua 90℃thiab lub tshuab condensate khiav tsis muaj qhov siab, lub viav vias valve yuav tsum raug kaw kom tsis txhob muaj cov pa tawm mus thiab ua rau cov dej cuam tshuam -.
(5) Kev hloov kho kev ua haujlwm: Kev hloov pauv kev ua haujlwm feem ntau yog raws li huab cua hloov pauv hloov pauv dej kub thiab dej ntws. Cov neeg khiav dej num feem ntau tswj cov cua kub hauv qhov dej ntws ntawm lub plhaub- thiab - raj kub exchanger nyob rau hauv thawj theem ntawm chav tsev kub los tswj lub qhov hluav taws xob dej kub. Thaum qhov kub ntawm sab nraum zoov yog siab, qhov kub thiab txias yog tswj los ntawm kev tswj tus naj npawb ntawm cov khoom siv khiav lag luam thiab kho qhov inlet steam flow rate. Txawm li cas los xij, kev saib xyuas yuav tsum tau ua kom txo qis qhov zaus ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob kom tsis txhob tawg ntawm lub sealing gasket vim nquag pib- nres. Thaum lub cua sov load txo qis, yuav tsum tau them nyiaj mloog mus rau cov kav dej hauv chav dej kom tsis txhob muaj dej rauj nyob rau hauv lub tshav kub exchanger. Kev hloov kho kev ua haujlwm yuav tsum tau ua nyob rau hauv ib qho kev sib koom ua ke thoob plaws hauv tag nrho cov kab ke thiab sib faib ua ke.
