Ngaphandle kwamajeneretha esitimu enziwe ngokwezifiso nahlanzekile, iningi lamajeneretha omusi enziwe nge-carbon steel. Uma zinganakekelwa ngesikhathi sokusetshenziswa, zijwayele ukugqwala. Ukunqwabelana kokugqwala kuzolimaza okokusebenza futhi kunciphise impilo yesevisi yemishini. Ngakho-ke, kudingekile kakhulu ukugcina kahle i-generator ye-steam futhi ususe ukugqwala.
1. Isondlo sansuku zonke
Ukuhlanzwa kwejeneretha ye-steam kuhlukaniswe izingxenye ezimbili. Enye ingxenye ukuhlanzwa kweshubhu yokuguqula umshini wokushisa umusi, ishubhu ye-superheater, isifudumezi somoya, isikali seshubhu yodonga lwamanzi kanye namabala okugqwala, okungukuthi, amanzi aphehla umusi kufanele aphathwe kahle, futhi umfutho ophakeme ungasetshenziswa. Ubuchwepheshe bokuhlanza i-jet yamanzi bungafinyelela imiphumela emihle ekuhlanzeni umzimba wesithando somlilo we-steam generator.
2. Ukwehliswa kwamakhemikhali kwejeneretha yesitimu
Engeza okokugeza ngamakhemikhali ukuze uhlanze, uhlukanise futhi ukhiphe ukugqwala, ukungcola namafutha ohlelweni futhi ukubuyisele endaweni ehlanzekile yensimbi. Ukuhlanzwa kwejeneretha ye-steam kuhlukaniswe izingxenye ezimbili. Enye ingxenye ukuhlanzwa kwamashubhu e-convection, amashubhu okushisa aphezulu, izifudumezi zomoya, amashubhu odongeni lwamanzi namabala okugqwala. Enye ingxenye ukuhlanzwa ngaphandle kwamashubhu, okungukuthi, ukuhlanzwa kwesithando somlilo se-steam generator. Hlanza.
Lapho wehlisa ngamakhemikhali ijeneretha yesitimu, kufanele futhi unake iqiniso lokuthi ukukhiqizwa kwesikali ku-generator yesitimu kunethonya elikhulu kunani le-PH, futhi inani le-PH alivunyelwe ukuthi libe phezulu kakhulu noma libe phansi kakhulu. Ngakho-ke, ukugcinwa kwansuku zonke kufanele kwenziwe kahle, futhi ukunakwa okwengeziwe kufanele kukhokhwe ekuvimbeleni insimbi ukuthi ingagqwali futhi ivimbele i-calcium ne-magnesium ion ukuthi ingafinyeleli futhi ifakwe. Kungale ndlela kuphela lapho i-jeneretha yesitimu ngokwayo ingaqinisekiswa khona ukuthi ingagqwali futhi inwetshwe impilo yayo yesevisi.
3. Indlela yokwehliswa kwemishini
Uma kunesikali noma i-slag esithandweni somlilo, khipha itshe lesithando somlilo ngemva kokuvala isithando somlilo ukuze upholise ijeneretha yesitimu, bese usishaya ngamanzi noma usihlanze ngebhulashi locingo oluvunguzayo. Uma isikali sinzima kakhulu, sebenzisa i-high-pressure water jet yokuhlanza, ukuhlanza ipayipi kagesi noma i-hydraulic ukuze uyihlanze. Le ndlela ingasetshenziswa kuphela ukuhlanza amapayipi ensimbi futhi ayifanele ukuhlanza amapayipi ethusi ngoba abahlanza amapayipi bangalimaza kalula amapayipi ethusi.
4. Indlela evamile yokususa isikali samakhemikhali
Kuye ngezinto zemishini, sebenzisa i-ejenti yokuhlanza ephephile futhi enamandla. Ukugxila kwesixazululo kuvame ukulawulwa ku-5 ~ 20%, okungabuye kunqunywe ngokusekelwe kubukhulu besikali. Ngemuva kokuhlanza, qala ngokukhipha uketshezi olulahlwayo, bese uhlanza ngamanzi ahlanzekile, bese ugcwalisa amanzi, engeza i-neutralizer cishe ngo-3% womthamo wamanzi, cwilisa bese ubilisa ihora elingu-0.5 kuya ku-1, khipha uketshezi olusele, bese uhlanza. ngamanzi ahlanzekile. Izikhathi ezimbili zanele.
