Yokutanga ndeyekudyisa mvura, ndiko kuti, kupinza mvura mubhaira. Kazhinji, inoshongedzerwa nepombi yakakosha kuita kuti nzira yekushandura mvura ive nyore uye nekukurumidza. Apo mvura inounzwa mubhailer, nokuti inotora kupisa kunobudiswa nekupisa kwemafuta, steam ine imwe dzvinyiriro, tembiricha uye kuchena kunooneka. Kazhinji, kuwedzera mvura kune bhaira kunofanira kupfuura nematanho matatu ekupisa, zvinoti: mvura yemvura inopisa kuti ive mvura yakasviba; mvura yakasviba inopisa uye inoputika kuti ive saturated steam; link.
Kazhinji, mvura inopihwa mudhiramu boiler inofanira kutanga yapiswa mueconomizer kune imwe tembiricha, yozotumirwa kune dhiramu kuti isanganise nemvura yeboiler, yobva yapinda mudunhu rekutenderera kuburikidza neanodzika, uye mvura inopisa. musimudziro Musanganiswa wemvura-yemvura inogadzirwa kana yasvika pakupisa kwekuzara uye chikamu chacho chinoputika; zvino, zvichienderana nekusiyana kwe density pakati pepakati musimudzi uye downcomer kana kumanikidzirwa kutenderera pombi, musanganiswa wemvura inopfungaira inokwira mudhiramu.
Iyo dhiramu mudziyo wecylindrical pressure inogamuchira mvura kubva mumoto wemarasha, inopa mvura kune inotenderera loop uye inoendesa yakazara mutsi kune superheater, saka zvakare chinongedzo pakati pematatu maitiro ekudziya kwemvura, evaporation uye superheating. Mushure mekunge musanganiswa wemvura-yemvura wapatsanurwa mudhiramu, mvura inopinda muchikamu chekutenderera kuburikidza neinodzika, nepo mhepo yakanyungudutswa inopinda mumhepo inopisa uye inopisa mumhepo ine imwe dhigirii yekupisa kukuru.
