Cov yam ntxwv cuam tshuam rau qhov kub thiab txias ntawm chav dej thiab qhov ntws ntws yog qhov hloov pauv ntawm lub tshuab hluav taws xob lub tshuab hluav taws xob, uas yog, kev hloov pauv ntawm lub hnub qub ntawm cov khoom siv hluav taws xob thiab qib siab hauv lub lauj kaub.Kev hloov pauv ntawm cov dej hauv lub lauj kaub kuj tseem yuav ua rau muaj kev hloov pauv ntawm cov av noo ntawm chav, thiab kev hloov pauv ntawm cov dej hauv dej kub thiab kev sib xyaw ua ke ntawm lub tshuab hluav taws xob yuav ua rau muaj kev hloov pauv ntawm cov khoom siv hluav taws xob.
Raws li ntau hom superheaters, qhov kub ntawm chav nyob hauv lub superheater sib txawv nrog cov load.Lub chav kub ntawm lub radiant superheater txo qis thaum lub load nce, thiab qhov opposite yog muaj tseeb rau lub convective superheater.Qhov siab dua cov dej hauv lub lauj kaub, qhov ntau dua cov av noo, thiab chav xav tau cua sov ntau hauv lub superheater, yog li qhov ntsuas kub yuav poob.
Yog tias qhov dej nkag ntawm lub tshuab hluav taws xob qis qis, yog li tus nqi ntawm cov dej ntws los ntawm lub rhaub dej txo qis, yog li cov cua sov absorbed hauv lub superheater yuav nce, yog li qhov kub ntawm qhov hluav taws xob ntawm lub superheater yuav txo.sawv.
