Isikali sisongela ngokuqondile ukuphepha nempilo yesevisi yedivayisi ye-steam generator ngoba ukuhanjiswa kwesikali esishisayo kuncane kakhulu.I-thermal conductivity of scale incane izikhathi ezingamakhulu kuneyensimbi.Ngakho-ke, noma ngabe isikali esingaminyene kakhulu sakhiwe endaweni yokushisa, ukusebenza kahle kokushisa kokushisa kuzoncishiswa ngenxa yokumelana okukhulu nokushisa, okuholela ekulahlekelweni kokushisa nokumosha uphethiloli.
Ukuzijwayeza kufakazele ukuthi i-1mm yesikali endaweni yokushisisa ye-steam generator ingakhuphula ukusetshenziswa kwamalahle cishe ngo-1.5 ~ 2%.Ngenxa yesilinganiso endaweni yokushisa, udonga lwamapayipi ensimbi luzoshiswa ngokwengxenye.Uma izinga lokushisa lodonga lidlula izinga lokushisa elivumelekile elilinganiselwe lokusebenza, ipayipi lizoqhuma, okungase kubangele ingozi yokuqhuma kwamapayipi futhi kusongela ukuphepha komuntu siqu.Isikali usawoti oyinkimbinkimbi oqukethe ama-halogen ions agqwalisa insimbi emazingeni okushisa aphezulu.
Ngokuhlaziywa kwesikali sensimbi, kungabonakala ukuthi okuqukethwe kwayo kwensimbi cishe ku-20 ~ 30%.Ukuguguleka kwesikali sensimbi kuzobangela udonga lwangaphakathi lwejeneretha yesitimu ukuba lushwabane futhi lugle kakhulu.Ngenxa yokuthi ukususa isikali kudinga ukucisha isithando somlilo, kudla izinsiza zabasebenzi kanye nezinto ezibonakalayo, futhi kubangela ukulimala kwemishini kanye nokugqwala kwamakhemikhali.
Ijeneretha ye-Nobeth steam inokuqapha isikali esizenzakalelayo kanye nedivayisi ye-alamu.Ikala ukukala odongeni lwamapayipi ngokuqapha izinga lokushisa lokuphuma komzimba.Uma kukhona ukukala okuncane ngaphakathi kubhayela, kuzokhala ngokuzenzakalelayo.Lapho isikali sinzima, sizophoqeleka ukuthi sivale ukuze kugwenywe ukukala.Ingozi yokuqhuma kwamapayipi kangcono yelula impilo yesevisi yemishini.
1. Indlela yokwehliswa kwemishini
Uma kunesikali noma i-slag esithandweni, khipha amanzi esithandweni ngemuva kokuvala isithando somlilo ukuze upholise i-jeneretha yesitimu, bese uyiphonsa ngamanzi noma usebenzise ibhulashi le-spiral wire ukuze uyisuse.Uma isikali sinzima kakhulu, singahlanzwa ngengulube yepayipi eqhutshwa ukuhlanzwa kwejethi yamanzi okucindezela okukhulu noma amandla we-hydraulic.Le ndlela ifaneleka kuphela ukuhlanza amapayipi ensimbi futhi ayifanele ukuhlanza amapayipi ethusi ngoba isicoci sepayipi singalimaza kalula amapayipi ethusi.
2. Indlela evamile yokususa isikali samakhemikhali
Ngokwempahla yemishini, khetha i-ejenti yokuhlanza ephephile futhi enamandla.Ngokuvamile, ukugxilwa kwesisombululo kulawulwa ku-5 ~ 20%, okungahle futhi kunqunywe ngokuvumelana nobukhulu besikali.Ngemuva kokuhlanza, qala ngokukhulula uketshezi olungcolile, bese uhlanza ngamanzi ahlanzekile, bese ugcwalisa amanzi, engeza i-neutralizer cishe ngo-3% womthamo wamanzi, cwilisa bese ubilisa amahora angu-0.51, ngemva kokukhipha uketshezi olusele, hlambulula kanye noma kabili. ngamanzi ahlanzekile.
Ukwakhiwa kwesikali kujeneretha yesitimu kuyingozi kakhulu.Ukukhipha amanzi njalo nokwehliswa kuyadingeka ukuze kuqinisekiswe ukusebenza okuvamile kwejeneretha ye-steam.
