Ngesikhathi sokuvalwa kwe-Steam generator, kunezindlela ezintathu zokulungisa:
1. Ukulungiswa kwengcindezi
Lapho i-boiler yegesi ivaliwe isikhathi esingaphansi kwesonto, ukulungiswa kwengcindezi kungasetshenziswa. Lokho wukuthi, ngaphambi kokuthi inqubo yokuvala i-shutdown inqanyuliwe, uhlelo lwamanzi alolothile lugcwele amanzi, ingcindezi eyinsalela igcinwa ku (0.05 ~ 0.1) I-MPA, futhi izinga lokushisa lamanzi embiza ligcinwa ngenhla kwe-100 ° C. Lokhu kungavimbela umoya ukuthi ungene ekungeneni i-boiler yegesi. Izinyathelo zokugcina ingcindezi kanye nokushisa ngaphakathi kwe-boiler yegesi yilezi: ukufudumeza ngomusi kusuka esithandweni esiseduze, noma ukufudumeza njalo ngesithando somlilo.
2. Ukulungiswa okumanzi
Lapho i-boiler yegesi ingaphandle kwensizakalo isikhathi esingaphansi kwenyanga eyodwa, ukulungiswa okumanzi kungasetshenziswa. Ukulungiswa okumanzi ukugcwalisa umusi we-boiler nohlelo lwamanzi ngamanzi athambile aqukethe isisombululo se-alkali, kungashiyanga isikhala esinamanzi. Ngoba isixazululo esinamanzi nge-alkalinity efanelekile singakha ifilimu elizinzile oxide endaweni yensimbi, ngaleyo ndlela kuvinjelwe ukugqwala kusuka ekuqhubekeni. Ngesikhathi senqubo yokulungiswa kwamanzi, i-oveni yomlilo ephansi kufanele isetshenziswe njalo ukuze igcine ingaphandle lendawo evuthayo yomile. Vula ipompo njalo ukujikeleza amanzi. Hlola i-alkalinity yamanzi njalo. Uma i-alkalinity incipha, engeza isixazululo se-alkaline ngokufanele.
3. Isondlo esomile
Lapho i-boiler yegesi ingasebenzi isikhathi eside, ukulungiswa komile kungasetshenziswa. Isondlo eyomile isho indlela yokubeka i-desiccant ebhodweni nesithando somlilo sokuvikelwa. Indlela ethile yilena: Ngemuva kokumisa ama-boiler, chitha amanzi embiza, sebenzisa izinga lokushisa elisele esithandweni sokomisa i-boiler yegesi, bese ubeka ugqoko oluqukethe i-desiccant esigubhini bese uvala ama-manholes kanye nama-manhole. Hlola isimo sokulungisa njalo bese ubeka esikhundleni se-desiccant ephelelwe yisikhathi ngesikhathi.
4. Ukulungiswa okuvuthayo
Ukulungiswa okungavumelani kungasetshenziselwa ukulungiswa kwe-turdown yesikhathi eside. Ngemuva kokuthi i-boiler yegesi ivaliwe, ungadedeli namanzi ukugcina izinga lamanzi lisezingeni eliphakeme lamanzi, lithathe izinyathelo zokufaka i-booxidizeze i-boiler yegesi, bese ihlukanisa amanzi e-boiler evela emhlabeni wangaphandle. Thela ku-nitrogen noma i-ammonia ukuze ulondoloze ingcindezi ngemuva kokunyuka kwamandla emali (0.2 ~ 0.3) MPA. Njengoba i-nitrogen ingaphendula nge-oxygen ukwakha i-nitrogen oxide, umoya-mpilo awukwazi ukuxhumana neplate yensimbi. Lapho i-ammonia ichithwa emanzini, yenza i-alkali yamanzi futhi ingavimba ngempumelelo ukugqwala komoya-mpilo. Ngakho-ke, bobabili i-nitrogen ne-ammonia yizindawo ezinhle zokugcina. Umphumela wokulungiswa kwemali okuvuthayo muhle, futhi ukulungiswa kwawo kudinga ukuqina okuhle komusi we-boiler nohlelo lwamanzi.
