A: Izinga lokushisa legesi eliwuflue lamajeneretha omusi avamile liphezulu kakhulu ngesikhathi sokusha, cishe amadigri angu-130, asusa ukushisa okukhulu. Ubuchwepheshe bokushiswa kwe-condensing ye-condensing generator yesitimu kunciphisa izinga lokushisa kwe-flue gas ukuya kuma-degrees angu-50, kufinyeza ingxenye yegesi e-flue ibe yisimo esiwuketshezi, futhi kubambe ukushisa kwegesi ephuma ku-flue kusuka esimweni segesi kuya esimweni soketshezi ukuze kubuyiselwe ukushisa ekuqaleni. ithathwe yi-flue gas. Ukusebenza kahle kwe-thermal kuphakeme kakhulu kunamajeneretha avamile we-steam.
Isilinganiso sokucindezela kwejeneretha yesitimu sihlukaniswa ngokuya ngebanga lokucindezela komphunga wamanzi wokuphuma kwe-steam generator. Imininingwane imi kanje:
I-Atmospheric pressure steam generator ngaphansi kwe-0.04MPa;
Ngokuvamile, ijeneretha yesitimu enomfutho womhwamuko wamanzi lapho kuphuma umshini okhiqiza isitimu ngaphansi kwe-1.9MPa ibizwa ngokuthi i-low-pressure steam generator;
Ijeneretha yesitimu enomfutho womusi wamanzi ongaba ngu-3.9MPa lapho kuphuma umshini wokuphehla umusi ubizwa ngokuthi i-medium-pressure steam generator;
Ijeneretha yesitimu enomfutho womhwamuko wamanzi ocishe ube ngu-9.8 MPa lapho kuphuma umshini wokuphehla umusi ubizwa ngokuthi i-high-pressure steam generator;
Ijeneretha yesitimu enengcindezi yomhwamuko wamanzi ecishe ibe ngu-13.97MPa lapho kuphuma ijeneretha yesitimu ibizwa ngokuthi i-ultra-high pressure steam generator;
Ijeneretha yesitimu enomfutho womhwamuko wamanzi ekuphumeni kwejeneretha yesitimu engaba ngu-17.3MPa ibizwa ngokuthi i-subcritical pressure steam generator;
Ijeneretha yesitimu enomfutho womhwamuko wamanzi ngaphezu kuka-22.12 MPa ekuphumeni kwejeneretha yesitimu ibizwa ngokuthi i-supercritical pressure steam generator.
I-gauge yokucindezela ingasetshenziswa ukukala inani langempela lokucindezela ku-generator ye-steam, futhi ukuguqulwa kwe-pointer ye-gauge ye-pressure gauge kungabonisa ukuguqulwa kokuvutha nomthwalo. I-gauge ye-pressure esetshenziswa ku-generator ye-steam kufanele ikhethwe ngokuvumelana nokucindezela kokusebenza. Isilinganiso esiphezulu senani lesilinganiso sokudayela kwegeyiji yomfutho wegesi kufanele sibe izikhathi ezingu-1.5~3.0 zokucindezela kokusebenza, okungcono izikhathi ezingu-2.
