Dej yog qhov nruab nrab tseem ceeb rau kev siv hluav taws xob hauv cov tshuab hluav taws xob.Yog li ntawd, lub tshuab hluav taws xob muaj hluav taws xob kho dej ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj txiaj ntsig, kev lag luam, kev nyab xeeb, thiab kev ua haujlwm ntawm cov tshuab hluav taws xob.Nws suav nrog cov qauv kev kho dej, dej condensed, dej ua kom zoo, thiab ntsuas qhov ntsuas thermal.Hauv ntau yam, nws qhia txog qhov cuam tshuam ntawm kev lag luam chav generator dej kho ntawm chav generator zog noj.
Cov dej zoo muaj qhov cuam tshuam tseem ceeb rau kev siv lub zog ntawm cov tshuab hluav taws xob.Cov teeb meem dej tsis zoo uas tshwm sim los ntawm kev kho dej tsis zoo feem ntau ua rau muaj teeb meem xws li kev ntsuas, kev txhim kho corrosion, thiab cov dej phwj tuaj ntawm lub tshuab hluav taws xob ntau ntxiv, ua rau txo qis thermal efficiency ntawm lub tshuab hluav taws xob, thiab thermal efficiency ntawm chav generator txhua. Qhov feem pua ntawm cov ntsiab lus txo qis yuav nce kev siv hluav taws xob los ntawm 1.2 txog 1.5.
Tam sim no, lub tshuab hluav taws xob muaj hluav taws xob hauv tsev kho dej tuaj yeem muab faib ua ob theem: kev kho dej sab nraum lub lauj kaub thiab kev kho dej hauv lub lauj kaub.Qhov tseem ceeb ntawm ob qho tib si yog kom tsis txhob muaj corrosion thiab scaling ntawm chav generator.
Lub hom phiaj ntawm cov dej sab nraum lub lauj kaub yog ua kom cov dej mos thiab tshem tawm cov impurities xws li calcium, oxygen, thiab magnesium hardness ntsev uas tshwm sim hauv cov dej nyoos los ntawm txoj kev kho lub cev, tshuaj thiab electrochemical;thaum cov dej hauv lub lauj kaub siv cov tshuaj siv tshuaj raws li txoj hauv kev kho mob.
Rau kev kho dej sab nraum lub lauj kaub, uas yog ib feem tseem ceeb ntawm chav generator dej kho, muaj peb theem.Txoj kev sib pauv sodium ion siv hauv kev kho dej softened tuaj yeem txo qhov tawv ntawm cov dej, tab sis cov alkalinity ntawm cov dej tsis tuaj yeem txo ntxiv.
Chav generator scaling tuaj yeem muab faib ua sulfate, carbonate, silicate nplai thiab sib xyaw nplai.Piv nrog rau cov tshuab hluav taws xob zoo tib yam steel, nws qhov kev hloov pauv cua sov tsuas yog 1/20 txog 1/240 ntawm qhov kawg.Fouling yuav txo tau qhov kev ua tau zoo ntawm cov hluav taws xob hloov hluav taws xob ntawm lub tshuab hluav taws xob, ua rau lub tshuab hluav taws xob combustion yuav raug tshem tawm los ntawm cov pa hluav taws xob, uas ua rau txo qis hauv lub tshuab hluav taws xob tso tawm thiab chav ua haujlwm zoo.Lmm fouling yuav ua rau 3% mus rau 5% roj poob.
Txoj kev sib pauv sodium ion tam sim no siv los kho softening yog qhov nyuaj kom ua tiav lub hom phiaj ntawm kev tshem tawm alkali.Txhawm rau kom ntseeg tau tias cov khoom siv siab tsis corroded, cov tshuab hluav taws xob ua haujlwm yuav tsum tau tswj los ntawm cov dej phwj tuaj thiab lub lauj kaub dej kho kom ntseeg tau tias cov alkalinity ntawm cov dej nyoos mus txog tus qauv.
Yog li, cov dej phwj tuaj ntawm cov tshuab hluav taws xob hauv tsev tau ib txwm nyob nruab nrab ntawm 10% thiab 20%, thiab txhua txhua 1% nce hauv cov dej phwj tuaj yeem ua rau cov roj poob nce ntxiv los ntawm 0.3% mus rau 1%, ua rau muaj kev txwv tsis pub siv hluav taws xob ntau. chav generators;Qhov thib ob, qhov nce ntawm cov ntsev cov ntsiab lus tshwm sim los ntawm co-evaporation ntawm dej qab zib thiab dej kuj yuav ua rau cov khoom puas tsuaj thiab ua rau kom lub zog noj ntawm lub tshuab hluav taws xob.
Muaj kev cuam tshuam los ntawm cov txheej txheem tsim khoom, cov tshuab hluav taws xob muaj hluav taws xob muaj peev xwm feem ntau yuav tsum tau nruab thermal deaerators.Muaj cov teeb meem tshwm sim hauv nws daim ntawv thov: kev noj ntau ntawm cov chav yuav txo tau qhov kev siv tau zoo ntawm cov cua sov ntawm lub tshuab hluav taws xob;qhov sib txawv ntawm qhov kub thiab txias ntawm cov dej kub ntawm lub tshuab hluav taws xob thiab qhov nruab nrab ntawm cov dej kub ntawm cov khoom siv hluav taws xob ua kom loj dua, uas ua rau cov pa hluav taws xob ntau dua.
