Ukusebenzisa ijeneretha ye-steam ukuvala inzalo emazingeni okushisa aphezulu akusheshi nje kuphela, kodwa futhi kuphephile futhi kuvikelekile. Kunezindlela eziningi zokungcoliswa yisikhunta ekukhiqizeni imikhiqizo yenyama. Imithombo yokungcola efana namanzi, umoya, nezitsha iyinkimbinkimbi futhi ihlanganisa zonke izixhumanisi kule nqubo. Ngakho-ke, kubalulekile ukukhetha indlela yokushisa yokushisa ephezulu yokuvala inzalo ye-steam generator enomphumela omuhle wokubulala amagciwane futhi engaba yingozi kangako kubantu nokudla ekucutshungulweni nasekukhiqizeni umkhiqizo wenyama. Indlela yokuvala inzalo yesitimu isetshenziswa kakhulu, futhi zonke izinto ezimelana nomswakama zingavalwa kusetshenziswa amajeneretha okushisa okushisa aphezulu. I-Steam inamandla okungena aqinile, umphumela oqinile wokuvala inzalo, kanye nesivinini sokuvala inzalo ngokushesha, futhi ingaqeda ngokushesha isikhunta. Ijeneretha yesitimu ishintsha amanzi abe isitimu ukuze kubulawe amagciwane ezingeni lokushisa eliphezulu. Ayinawo amakhemikhali futhi iphephile futhi inokwethenjelwa.
Ukuvala inzalo kusetshenziselwa ukususa noma ukuqeda ama-microorganisms e-pathogenic endaweni yokudlulisela. Ijeneretha yokushisa yokushisa ephezulu yokuvala inzalo iyenza ihlangabezane nezidingo zokungangcoli futhi ivimbele ngempumelelo ukusabalala kwama-microorganisms endaweni yokusebenzela yomkhiqizo wenyama. Imikhiqizo yenyama inothile ngamaprotheni namafutha futhi iwumthombo omuhle wemisoco yama-microorganisms. Ukuhlanzeka ngesikhathi sokucubungula kuyisidingo sokuqala sokuqinisekisa ikhwalithi nokuphepha kwemikhiqizo yenyama. Indlela yokuvala inzalo yesitimu isetshenziswa kakhulu, futhi zonke izinto ezimelana nomswakama zingavalwa kusetshenziswa amajeneretha okushisa okushisa aphezulu. I-Steam inamandla okungena aqinile kanye nomphumela oqinile wokuvala inzalo. I-steam enezinga eliphezulu lokushisa ingena kumaseli ebhaktheriya bese ishintsha ngokushesha futhi iqinise amaprotheni ebhaktheriya aze afe ngesikhathi esifushane. Ijeneretha yesitimu evala izinga lokushisa eliphezulu iguqula ngokuqondile amanzi abe isitimu ngaphandle kokunye ukungcola noma amakhemikhali. Ukuphepha kwemikhiqizo yenyama eyinzalo kuqinisekisiwe.
