Ungawasusa kanjani amagesi angacondensable njengomoya kumasistimu we-steam?

Imithombo eyinhloko yamagesi angacondensable njengomoya kumasistimu omusi imi kanje:
(1) Ngemva kokuvalwa kwesistimu yesitimu, kukhiqizwa i-vacuum futhi kufakwe umoya
(2) Amanzi e-boiler feed ahambisa umoya
(3) Ukuhlinzeka ngamanzi namanzi ajiyile kuthinta umoya
(4) Indawo yokondla kanye neyokuthulula impahla yokushisisa ngezikhathi ezithile

Amagesi angacondensable ayingozi kakhulu kumasistimu e-steam nama-condensate
(1) Ikhiqiza ukumelana nokushisa, ithinta ukudluliswa kokushisa, inciphisa ukuphuma kwesishintshi sokushisa, ikhulise isikhathi sokushisa, futhi ikhulise izidingo zokucindezela kwesitimu.
(2) Ngenxa yokungaphatheki kahle komoya okushisayo, ukuba khona komoya kuzodala ukushisa okungalingani komkhiqizo.
(3) Njengoba izinga lokushisa le-steam kugesi elingacondensable alikwazi ukunqunywa ngokusekelwe kugeji yokucindezela, lokhu akwamukeleki ezinkambisweni eziningi.
(4) I-NO2 ne-C02 equkethwe emoyeni ingakwazi ukugqwala kalula ama-valve, ama-heater exchangers, njll.
(5) Igesi engacondensable ingena ohlelweni lwamanzi e-condensate ibangele isando samanzi.
(6) Ukuba khona komoya ongu-20% endaweni yokushisisa kuzobangela izinga lokushisa lesitimu lehle ngaphezu kuka-10°C. Ukuze kuhlangatshezwane nesidingo sezinga lokushisa le-steam, isidingo somfutho we-steam sizokhuphuka. Ngaphezu kwalokho, ukuba khona kwegesi engacondensable kuzobangela ukuthi izinga lokushisa le-steam lehle kanye nokukhiya kwesitimu esibucayi ohlelweni lwe-hydrophobic.

Phakathi kwezingqimba ezintathu zokumelana nokushisa okushisayo ohlangothini lwe-steam - ifilimu yamanzi, ifilimu yomoya kanye nongqimba lwesikali:

Ukumelana nokushisa okukhulu kakhulu kuvela kungqimba lomoya. Ukuba khona kwefilimu yomoya endaweni yokushintshanisa ukushisa kungabangela izindawo ezibandayo, noma okubi nakakhulu, kuvimbele ngokuphelele ukudluliswa kokushisa, noma okungenani kubangele ukushisa okungalingani. Eqinisweni, ukumelana komoya okushisayo kungaphezu kuka-1500 izikhathi zensimbi nensimbi, futhi izikhathi ezingu-1300 kunezethusi. Lapho isilinganiso somoya esinqwabelene esikhaleni sokushintsha ukushisa sifinyelela ku-25%, izinga lokushisa lesitimu lizokwehla kakhulu, ngaleyo ndlela linciphise ukusebenza kahle kokudlulisa ukushisa futhi kuholele ekuhlulekeni kokuvala inzalo ngesikhathi sokuvala inzalo.

Ngakho-ke, amagesi angacondensable ohlelweni lwe-steam kufanele aqedwe ngesikhathi. Ivalvu yokukhipha umoya esetshenziswa kakhulu emakethe ye-thermostatic okwamanje iqukethe isikhwama esivaliwe esigcwele uketshezi. Indawo yokubilisa yoketshezi iphansi kancane kunezinga lokushisa lokugcwala kwesitimu. Ngakho lapho isitimu esihlanzekile sizungeza isikhwama esivaliwe, uketshezi lwangaphakathi luyahwamuka futhi ukucindezela kwalo kubangela ukuba i-valve ivaleke; lapho kunomoya kusitimu, izinga lokushisa layo liphansi kunesitimu esihlanzekile, futhi ivalvu ivuleka ngokuzenzakalelayo ukuze ikhulule umoya. Lapho okuzungezile kuyisitimu esihlanzekile, i-valve iyavala futhi, futhi i-valve yokukhipha i-thermostatic isusa ngokuzenzakalelayo umoya nganoma isiphi isikhathi phakathi nalo lonke uhlelo lwe-steam. Ukususwa kwamagesi angacondensable kungathuthukisa ukudluliswa kokushisa, konga amandla futhi kwandise umkhiqizo. Ngesikhathi esifanayo, umoya ususwa ngesikhathi ukuze kugcinwe ukusebenza kwenqubo ebalulekile ekulawuleni izinga lokushisa, ukwenza ukushisa okufanayo, nokuthuthukisa ikhwalithi yomkhiqizo. Yehlisa ukugqwala kanye nezindleko zokunakekela. Ukusheshisa isivinini sokuqalisa kohlelo kanye nokunciphisa ukusetshenziswa kokuqalisa kubalulekile ukuze kuthululwe amasistimu okushisa isitimu esikhaleni esikhulu.

I-valve yokukhipha umoya yohlelo lwesitimu ifakwa kangcono ekugcineni kwepayipi, ekhoneni elifile lezinto zokusebenza, noma indawo yokugcina imishini yokushintshanisa ukushisa, ehambisana nokuqoqwa nokuqedwa kwamagesi angacondensable. . I-valve yebhola yezandla kufanele ifakwe phambi kwe-valve yokukhipha i-thermostatic ukuze isitimu singakwazi ukumiswa ngesikhathi sokulungiswa kwe-valve yokukhipha umoya. Lapho uhlelo lwe-steam luvaliwe, i-valve yokukhipha i-exhaust ivuliwe. Uma ukugeleza komoya kudinga ukuhlukaniswa nezwe langaphandle ngesikhathi sokuvala, ivalvu yokuhlola i-soft-sealing check valve encane ingafakwa phambi kwe-exhaust valve.
