Thaum lub tshuab hluav taws xob tsim hluav taws xob tsim hluav taws xob, nws raug tso tawm los ntawm lub qhov cub lub cev ntawm lub boiler, thiab cov pa tawm ntawm lub boiler ib txwm muaj me ntsis impurity, qee qhov impurities muaj nyob rau hauv cov kua hauv lub xeev, qee qhov impurities tuaj yeem yaj hauv chav, thiab yuav muaj. kuj yog ib qho me me ntawm gaseous impurities sib xyaw hauv chav, xws li impurities feem ntau yog sodium ntsev, silicon ntsev, carbon dioxide thiab ammonia.
Thaum cov chav nrog impurities dhau los ntawm lub superheater, qee qhov impurities tuaj yeem sau rau ntawm phab ntsa sab hauv ntawm lub raj, uas ua rau ntsev nplai, uas yuav ua rau kom kub ntawm phab ntsa, ua kom lub zog tensile ntawm cov hlau, thiab txawm tias ua rau tawg loj heev. rooj plaub.Qhov seem impurities nkag mus rau chav turbine ntawm lub boiler nrog lub chav.Cov chav nthuav dav thiab ua haujlwm hauv chav turbine.Vim qhov poob ntawm chav siab, impurities yog precipitated thiab accumulated nyob rau hauv lub ntws ib feem ntawm lub chav turbine, uas ua rau cov ntxhib saum npoo ntawm cov hniav, kev kho cov kab zoo thiab txo cov chav ntws seem, uas ua rau ib tug txo nyob rau hauv cov zis thiab efficiency ntawm. chav turbine.
Tsis tas li ntawd, cov ntsev cov ntsiab lus khaws cia hauv lub ntsiab chav valve yuav ua rau nws nyuaj rau qhib lub valve thiab kaw nws laxly.Raws li rau cov chav ntau lawm thiab cov khoom yog nyob rau hauv kev sib cuag ncaj qha, yog hais tias lub impurity muaj nyob rau hauv lub chav yog ntau tshaj li tus nqi teev, nws yuav cuam tshuam rau cov khoom zoo thiab cov txheej txheem.Yog li ntawd, qhov zoo ntawm cov chav xa los ntawm chav generator yuav tsum ua tau raws li cov qauv kev cai, thiab kev ua kom huv ntawm chav boiler tau dhau los ua ib qho tseem ceeb, yog li cov chav boiler ntawm chav generator yuav tsum tau kho nrog chav purification.
