Q: Siyini isigubhu sikaSteam se-generator emfutho?

A:

1. I-Steam Drum ye-Steam Generator

I-Steam Drum iyimishini ebaluleke kakhulu emishini ye-Steam Generator. Kuyisixhumanisi phakathi kwezinqubo ezintathu zokushisa, i-vaporhanization kanye nokushisa ngokweqile kwe-Steam generator, futhi kudlala indima exhumayo.

Izinga lamanzi lesigubhu seSteam Drum Boiler yisikhombi esibaluleke kakhulu ngesikhathi sokusebenza kwe-boiler. Kuphela lapho izinga lamanzi ligcinwa ngaphakathi kobubanzi obujwayelekile kungajikeleza kahle kanye nokuhwamuka kwe-boiler kuqinisekiswe. Uma izinga lamanzi liphansi kakhulu ngesikhathi sokusebenza, lizodala ukuthi i-boiler ibe ngamafuphi amanzi. Ukushoda okukhulu kwamanzi ama-boiler kuzodala udonga lwamanzi we-wolling tube ukuze ngaphezulu, futhi kubangele ukulimala kwemishini.

Uma izinga lamanzi liphezulu kakhulu ngesikhathi sokusebenza kwe-boiler, isigubhu seSteam sizogcwaliswa ngamanzi, esizokwenza ukuthi izinga lokushisa eliyinhloko liyehla ngokushesha. Ezimweni ezinzima, amanzi azolethwa eTurbine nge-Steam, ebangela umthelela omkhulu kanye nomonakalo we-turbine blades.

Ngakho-ke, izinga elijwayelekile lamanzi wesigubhu kumele liqinisekiswe ngesikhathi sokusebenza kwe-boiler. Ukuze uqinisekise izinga elijwayelekile lamanzi wesigubhu, imishini ye-boiler ivame ukuhlonguswa ngokuvikelwa okuphezulu nokuphansi kwamanzi wesigubhu namasistimu wokulawula ukulungiswa kwamanzi. Izinga lamanzi lesigubhu livame ukuhlukaniswa libe yinani lokuqala eliphakeme, inani lesibili lesibili nenani eliphakeme lesithathu. Izinga lamanzi aphansi le-Drum lihlukaniswe nenani lokuqala eliphansi, inani lesibili lesibili nenani lesithathu eliphansi.

2. Ngesikhathi sokusebenza okujwayelekile kwe-boiler, yini imfuneko ye-Drum Water Level?

Iphuzu le-zero leleveli yamanzi yesigubhu se-Drive-Pressure Desrum Boiler ngokuvamile isethwe ku-50 mm ngaphansi komugqa wesikhungo sejometri. Ukuzimisela kwezinga elijwayelekile lamanzi lesigubhu seSteam, okungukuthi, izinga lamanzi we-zero, linqunywa yizici ezimbili. Ukuze uthuthukise ikhwalithi ye-Steam, indawo yesikhumba yesigubhu seSteam kufanele inyuswe ngangokunokwenzeka ukuze ugcine izinga lamanzi ajwayelekile liphansi.

Kodwa-ke, ukuze uqinisekise ukuphepha kokusakazwa kwamanzi futhi uvikele ukufuduka kanye nokungena emthelweni emnyango we-DownPipe, izinga elijwayelekile lamanzi kufanele ligcinwe liphakeme ngangokunokwenzeka. Ngokuvamile, izinga elijwayelekile lamanzi libekwe phakathi kuka-50 no-200 mm ngaphansi komugqa wesikhundla wesigubhu. Ngaphezu kwalokho, amazinga afanele aphezulu nangaphansi wamanzi we-boiler ngayinye kufanele anqunywe ngokusekelwe ekuhlolweni kwezilinganiso zamanzi zodonga oludonswe ngaphansi kwamanzi kanye nemiphumela yokuhlolwa kwekhwalithi yamanzi nokukalwa kwekhwalithi yamanzi. Phakathi kwazo, izinga lamanzi aphezulu linqunywa ukuthi ikhwalithi ye-vapor yamanzi iyawohloka; Izinga lamanzi aphansi aphansi kufanele linqunywe ukuthi ngabe umkhathi wokufuduka kanye nokufakwa okuthembile kwenzeka emnyango we-DownPipe.
