Tom qab lub tshuab hluav taws xob tsis siv, ntau qhov chaw tseem nyob hauv dej, thiab tom qab ntawd cov dej vapor yuav txuas ntxiv evaporate, uas yuav ua rau muaj dej ntau hauv cov dej qab zib, lossis ua rau muaj teeb meem corrosion hauv lub tshuab hluav taws xob.Yog li ntawd rau lub tshuab hluav taws xob, qhov twg yog qhov yooj yim rau corroded?
1. Lub tshav kub exchanger qhov chaw ntawm lub tshuab hluav taws xob yog yooj yim heev rau corrode thaum lub sij hawm ua hauj lwm, tsis hais lub tshav kub exchanger tom qab kaw.
2. Thaum cov phab ntsa dej ua haujlwm, nws cov pa tawm cov pa tawm tsis zoo, thiab nws lub nruas nruas thiab cov downcomer yooj yim heev rau corrode.Nws yog ib qho yooj yim rau corrode thaum lub sij hawm ua hauj lwm, thiab sab ntawm cov dej-txias phab ntsa chav nruas yog tshwj xeeb tshaj yog hnyav tom qab lub cub tawg kaw.
3. Ntawm lub luj tshib txoj hauj lwm ntawm ntsug superheater ntawm lub tshuab hluav taws xob, vim tias nws tau muab tso rau hauv dej rau lub sijhawm ntev, cov dej ntim tsis tuaj yeem raug tshem tawm kom huv, uas tseem ua rau nws corrode sai.
4. Lub reheater yog tib yam li cov ntsug superheater, qhov tseem ceeb ntawm lub luj tshib yog immersed nyob rau hauv dej thiab corroded.
