Izici ezithinta izinga lokushisa lesitimu esigcwele kanye nezinga lokugeleza ngokuyinhloko ukushintsha komthwalo wejeneretha yesitimu, okungukuthi, ukulungiswa kwenkanyezi yokukhiqiza umusi kanye nezinga lokucindezela ebhodweni.Ukushintsha kwezinga lamanzi ebhodweni nakho kuzodala izinguquko kumswakama wesitimu, futhi izinguquko ezingeni lokushisa lamanzi angenayo nezimo zokusha zejeneretha yesitimu nakho kuzodala izinguquko ekukhiqizeni isitimu.
Ngokusho kwezinhlobo ezahlukene zama-superheaters, izinga lokushisa le-steam ku-superheater liyahlukahluka ngomthwalo.Izinga lokushisa lesitimu le-superheater ekhazimulayo liyehla njengoba umthwalo ukhula, futhi okuphambene kuyiqiniso ku-convective superheater.Uma izinga lamanzi liphakeme ebhodweni, kulapho umswakamo wesitimu uphakama, futhi isitimu sidinga ukushisa okukhulu ku-heater enkulu, ngakho izinga lokushisa lesitimu lizokwehla.
Uma izinga lokushisa lamanzi angenayo le-steam generator liphansi, ngakho-ke inani le-steam eligeleza ku-heater liyancipha, ngakho-ke ukushisa okufakwe ku-superheater kuzokwanda, ngakho izinga lokushisa le-steam ekuphumeni kwe-superheater lizokwehla.vuka.
