1. Isitimu esigcwele
I-steam engazange ifakwe ukushisa ibizwa ngokuthi i-saturated steam.Igesi engenambala, engenaphunga, evuthayo futhi engagqwali.Isitimu esigcwele sinezici ezilandelayo.
(1) Kukhona ukuxhumana okukodwa phakathi kwezinga lokushisa nokucindezela kwesitimu esigcwele, futhi kukhona okuhlukile okukodwa kuphela okuzimele phakathi kwakho.
(2) Isitimu esigcwele kulula ukusihlanganisa.Uma kukhona ukulahlekelwa ukushisa phakathi nenqubo yokudlulisela, amaconsi awuketshezi noma inkungu ewuketshezi izokwakheka kusititi, okuholela ekwehleni kwezinga lokushisa nokucindezela.Isitimu esinamaconsi awuketshezi noma inkungu ewuketshezi ibizwa ngokuthi isitimu esimanzi.Uma sikhuluma ngokuqinile, umhwamuko ogcwele ucishe ube uketshezi lwezigaba ezimbili oluqukethe amaconsi awuketshezi noma inkungu ewuketshezi, ngakho-ke izimo ezihlukene azikwazi ukuchazwa sibalo esifanayo sesimo segesi.Okuqukethwe kwamaconsi awuketshezi noma inkungu ewuketshezi kusitimu esigcwele kubonisa ikhwalithi yesitimu, ngokuvamile esivezwa ipharamitha yokoma.Ukoma kwesitimu kubhekisela kumaphesenti esitimu esomile kuvolumu yeyunithi yesitimu esigcwele, esimelelwa ngokuthi “x”.
(3) Kunzima ukulinganisa ngokunembile ukugeleza kwesitimu esigcwele, ngoba ukoma kwesitimu esigcwele kunzima ukuqinisekiswa, futhi ama-flowmeters ajwayelekile awakwazi ukubona ngokunembile ukugeleza koketshezi oluyizigaba ezimbili, nokuguquguquka komfutho wesitimu kuzodala izinguquko kumusi. ukuminyana, kanye namaphutha engeziwe azokwenzeka kuzinkomba zama-flowmeters .Ngakho-ke, esilinganisweni somusi, kufanele sizame ukugcina ukoma kwesitimu endaweni yokulinganisa ukuze sihlangabezane nezidingo, futhi sithathe izinyathelo zesinxephezelo uma kudingekile ukuze sifinyelele isilinganiso esinembile.
2. Umusi oshisa kakhulu
I-Steam iyisisetshenziswa esikhethekile, futhi ngokuvamile, isitimu sisho isitimu esishisa kakhulu.Isitimu esishisa kakhulu siwumthombo wamandla ovamile, ovame ukusetshenziselwa ukushayela i-steam turbine ukuze ujikeleze, bese ushayela i-generator noma i-compressor ye-centrifugal ukuze isebenze.Isitimu esishisa kakhulu sitholakala ngokushisisa isitimu esigcwele.Ayinawo nhlobo amaconsi awuketshezi noma inkungu ewuketshezi, futhi ingeyegesi yangempela.Izinga lokushisa kanye nemingcele yengcindezi yesitimu esishisa kakhulu yimingcele emibili ezimele, futhi ukuminyana kwayo kufanele kunqunywe yile mingcele emibili.
Ngemuva kokuthi i-steam eshisa kakhulu ihanjiswe ibanga elide, ngokushintsha kwezimo zokusebenza (ezifana nezinga lokushisa nokucindezela), ikakhulukazi uma izinga lokushisa eliphakeme lingekho phezulu, lizongena ku-saturation noma i-supersaturation kusukela esimweni esishisayo ngenxa yokuncipha. isimo sezinga lokushisa lokulahlekelwa ukushisa, siguquke sibe isitimu esigcwele noma isitimu esigcwele kakhulu esinamaconsi amanzi.Lapho isitimu esigcwele sincishiswa ngokuzumayo futhi kakhulu, uketshezi luzophinda lugcwale isitimu noma isitimu esigcwele kakhulu esinamaconsi amanzi lapho sinwebeka ngokulingana.Isitimu esigcwele sincipha ngokuzumayo kakhulu, futhi uketshezi luzophinde luguqulwe lube isitimu esishisa kakhulu lapho lunwebeka ngokulingana, ngaleyo ndlela kwakheka umhwamuko-uketshezi olunezigaba ezimbili zokugeleza.
