Lapho ijeneretha yesitimu yenza isitimu futhi ikhuphula izinga lokushisa nokucindezela, ngokuvamile kuba khona umehluko wezinga lokushisa phakathi kwebhamuza elihambisana nogqinsi naphakathi kwezindonga ezingenhla nezingaphansi. Lapho izinga lokushisa lodonga lwangaphakathi liphakeme kunelodonga lwangaphandle futhi izinga lokushisa lodonga olungaphezulu liphakeme kunelo eliphansi, ukuze ugweme ukucindezeleka okushisayo ngokweqile, i-boiler kufanele ikhulise ukucindezela kancane kancane.
Lapho i-generator ye-steam ivutha ukuze ikhulise ukucindezela, imingcele ye-steam, izinga lamanzi kanye nezimo zokusebenza zezingxenye ze-boiler zishintsha njalo. Ngakho-ke, ukuze ugweme ngempumelelo izinkinga ezingavamile nezinye izingozi ezingaphephile, kuyadingeka ukuhlela abasebenzi abanolwazi ukuze baqaphe ngokucophelela izinguquko zemishini ehlukahlukene.
Ngokuvumelana nokulungiswa nokucindezela kokulawula, izinga lokushisa, izinga lamanzi kanye neminye imingcele yenqubo ingaphakathi kwebanga elithile elivumelekile, ngesikhathi esifanayo, ukuzinza kanye nesici sokuphepha samathuluzi ahlukahlukene, ama-valve nezinye izingxenye kufanele kuhlolwe, indlela yokuqinisekisa ngokugcwele ukusebenza okuphephile nokuzinzile kwejeneretha ye-steam.
Lapho umfutho wejeneretha yesitimu uphezulu, amandla asetshenziswa kakhulu, kanye nengcindezi emshinini ohambisanayo osebenzisa isitimu, uhlelo lwawo lwamapayipi namavalvu azokhula kancane kancane, okuzobeka phambili izidingo zokuvikela nokugcinwa kwejeneretha yesitimu. Njengoba ingxenye ikhula, ingxenye yokukhishwa kokushisa nokulahlekelwa okubangelwa isitimu ngesikhathi sokwakheka nokuthutha nayo izokhula.
Usawoti oqukethwe ku-steam-high-pressure nawo uzokwanda ngokunyuka kwengcindezi. Lawa masawoti azokwakha izenzakalo zesakhiwo ezindaweni ezishisayo njengamapayipi odongeni apholise ngamanzi, amapayipi, nezigubhu, okubangela izinkinga ezifana nokushisa ngokweqile, ukukhihliza amagwebu, nokuvaleka. Banga izinkinga zokuphepha ezifana nokuqhuma kwamapayipi.
