Kungani ijeneretha yesitimu ingadingi ukuhlolwa, futhi ngeke iqhume?
Okokuqala, umthamo wejeneretha ye-steam mncane kakhulu, futhi umthamo wamanzi awudluli u-30L, ongaphakathi kochungechunge lomkhiqizo wokuhlola kazwelonke wamahhala. Amajeneretha omusi akhiqizwa abakhiqizi abajwayelekile anezinhlelo eziningi zokuvikela. Uma inkinga seyenzekile, okokusebenza kuzonqamula ugesi ngokuzenzakalelayo.
Isistimu yokuvikela eminingi yomkhiqizo:
① Ukuvikela ukushoda kwamanzi: Izisetshenziswa ziphoqeleka ukuthi zivale isishisi ngenxa yokushoda kwamanzi.
② I-alamu yezinga lamanzi aphansi: i-alamu yezinga eliphansi lamanzi, cisha isishisi.
③Ukuvikelwa kokucindezela ngokweqile: isistimu izoxwayisa ngokucindezela ngokweqile futhi ivale isishisi.
④ Ukuvikelwa kokuvuza: Isistimu ithola ukunikezwa kwamandla okungavamile futhi ivale ngamandla ukunikezwa kwamandla. Lezi zinyathelo zokuzivikela zivinjelwe kakhulu, futhi uma kunenkinga, imishini ngeke iqhubeke nokusebenza futhi ngeke iqhume.
Kodwa-ke, njengemishini ekhethekile ebalulekile evame ukusetshenziswa ekuphileni kwansuku zonke nokukhiqizwa, ama-generator e-steam anezinkinga eziningi zokuphepha ngesikhathi sokusetshenziswa. Uma singakwazi ukuqonda futhi sibambe kahle izimiso zalezi zinkinga, singagwema ngempumelelo izingozi zokuphepha.
1. I-valve yokuphepha ye-steam generator: I-valve yokuphepha ingenye yemishini yokuphepha ebaluleke kakhulu kubhayela, engakhulula futhi inciphise ukucindezela ngesikhathi lapho ukucindezela kucindezelwe ngokweqile. Ngesikhathi sokusetshenziswa kwe-valve yokuphepha, ukukhishwa okuvamile okwenziwa ngesandla noma ukuhlolwa okusebenzayo okuvamile kuyadingeka ukuze kuqinisekiswe ukuthi ngeke kube nezinkinga ezifana nokugqwala nokunamathela okwenza i-valve yokuphepha ihluleke.
2. Igeji yezinga lamanzi ekhiqiza isitimu: Igeji yezinga lamanzi ekhiqiza isitimu iyithuluzi elibonisa ngokunembile izinga lamanzi kujeneretha lesitimu. Kuyiphutha elikhulu lokusebenza elingaphezulu noma elingaphansi kwezinga elivamile lamanzi legeji lezinga lamanzi, elingaholela kalula ezingozini. Ngakho-ke, igeji yezinga lamanzi kufanele igezwe njalo futhi izinga lamanzi kufanele libhekwe eduze ngesikhathi sokusetshenziswa.
3. Isilinganiso somfutho we-steam generator: Igeji yokucindezela ngokunembile ibonisa inani lengcindezi yokusebenza kubhayela, okubonisa ukuthi umqhubi akumelwe asebenze ngaphansi kwengcindezi eyeqile. Ngakho-ke, igeji yokucindezela iyadingeka ukuthi ilinganiswe njalo ezinyangeni eziyisithupha ukuze kuqinisekiswe ukuzwela nokwethembeka.
4. Idivayisi ye-Blowdown generator: Idivayisi yokukhipha umoya iyisisetshenziswa esikhipha isikali nokungcola kujeneretha yesitimu, esingalawula ngempumelelo ijeneretha yesitimu ekulinganisweni nasekunqwabeleni kwe-slag. Ngesikhathi esifanayo, ngokuvamile thinta ipayipi elingemuva le-valve ye-blowdown ukuze uhlole ukuthi kukhona ukuvuza. .
5. Ijeneretha ye-atmospheric pressure steam: Uma i-atmospheric pressure boiler ifakwe ngendlela efanele, ngeke kube khona inkinga yokuqhuma kokucindezela okukhulu, kodwa i-atmospheric pressure boiler boiler kumele inake i-antifreeze ebusika. Uma ipayipi liba yiqhwa laze lafa, kufanele lincibilikiswe mathupha ngaphambi kokusetshenziswa, ngaphandle kwalokho ipayipi lizolimala. Kubaluleke kakhulu ukumisa ukuqhuma kwe-overpressure.
