Ukusetyenziswa kweejenereyitha zomphunga ekucoceni inqanawa kuthetha ukuba umhlwa unokuthintelwa ngokufanelekileyo ngokucocwa rhoqo kweekhemikhali zesixhobo.
Isixhobo sejenereyitha yomphunga sisixhobo sekhemikhali esishushu esifudumeza amanzi ukuya kwindawo egcweleyo kwaye iwaguqule abe ngubushushu obuphezulu kunye nomphunga woxinzelelo oluphezulu.
Okwangoku, isetyenziswa kakhulu kwiikhemikhali, amayeza, imveliso yokutya kunye nezinye iindawo, kwaye isetyenziswa kakhulu kwiikhemikhali kunye namayeza.
Kwimveliso yeekhemikhali, imathiriyeli ekrwada kufuneka ifudunyezwe, ipholiswe kwaye ifakwe ikristale.
Ukuze kuthintelwe ukuwohloka kwemveliso okanye ukubola kunye nokuqinisekisa umgangatho wemveliso, ukucocwa rhoqo kweekhemikhali ngokuqhelekileyo kufunwa ukufezekisa injongo yokucoca.
1. Ngethuba lokusetyenziswa kwejenereyitha ye-steam, ukulawulwa kweqondo lokushisa eliqinileyo ngokuqhelekileyo kuyadingeka, kwaye izixhobo zokukhusela ukhuseleko zifakwe.
Xa ijenereyitha yomphunga isebenza ngokuqhelekileyo, ngokuqhelekileyo akukho bushushu okanye ubushushu obuphantsi.Nangona kunjalo, ukuba i-generator ye-steam ayicocwanga ngokwekhemikhali okanye igcinwe ixesha elide, ubomi bayo benkonzo buya kuchaphazeleka.Ukongezelela, iingxaki ezifana nokugqwala kunye nokungcola zinokuthi zenzeke ngexesha lokusetyenziswa kwejenereyitha yomphunga.Ukuba ayicocwanga ngexesha, iya kubangela ukubola kunye nokunyuka ngaphakathi kwesixhobo.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukusetyenziswa okuqhelekileyo kwejenereyitha ye-steam, ukwandisa ubomi benkonzo yayo, ukuqinisekisa ukuveliswa okukhuselekileyo kunye nendawo ecocekileyo, kunye nokuphucula inzuzo yezoqoqosho, ukucocwa kweekhemikhali kufuneka kuqhutywe rhoqo ngexesha lokusetyenziswa.
2 Ijeneretha ye-steam inokuxhotyiswa nge-condenser ehambelanayo, i-deaerator kunye negumbi lokufudumala.
I-condenser inokukhupha amanzi adibeneyo obushushu bokufudumala kwaye ihlukanise ukusuka emoyeni ukuphepha ukuphendula kwamanzi kunye ne-oksijini.I-deaerator isusa ukufuma okusemoyeni okanye iyenze ingakwazi ukumelana nomphunga oshushu.Igumbi lokufudumeza liphakamisa ubushushu bomphunga ukuya kwimeko ehluthisiweyo ngokujikeleza kweoli yokuhambisa ubushushu, kwaye iyiguqule ibe ngumphunga ogcweleyo ukuze usetyenziswe.Igumbi lokufudumeza lixhotyiswe ngesixhobo sokuzalisa amanzi ngokuzenzekelayo kunye nesixhobo sokukhupha umphunga, esinokuzalisa ukunikezelwa kwamanzi ngexesha lokujikeleza.
3. Ijeneretha ye-steam inekhono elihle lokuchasana ne-corrosion, elinokucoca izixhobo ngaphandle kokuchaphazela imeko yokusetyenziswa kwangaphakathi kwesixhobo.Ngoko ke, izixhobo zejenereyitha zomphunga zinamandla okuchasa ukubola kunye nokucoca, kwaye unyango oluhlukeneyo lunokwenziwa ngaphakathi kwesixhobo ngaphandle kokuchaphazela urhulumente wokusetyenziswa kwangaphakathi.
4. Inkqubo yokulawula ngokuzenzekelayo ngokuzenzekelayo isetyenziswe ngaphakathi kwejeneretha ye-steam ukuze kuqinisekiswe inkqubela phambili yomsebenzi wokucoca.Ukongezelela, i-generator ye-steam ingasetyenziselwa ukucoca kunye nokugcinwa kotshintshiselwano lokushisa, ngaloo ndlela yandisa ubomi benkonzo.Iindlela zokucoca iikhemikhali zejeneretha ye-steam ikakhulu ziquka: ukucwiliswa, ukujikeleza, ukutshiza, njl., Enokuphelisa ngokufanelekileyo okanye ukunciphisa iimveliso ze-corrosion kunye nokufezekisa injongo yokuthintela ukubola.
Umthetho-siseko wokususwa komhlwa ngekhemikhali ngejenereyitha yomphunga: yongeza i-agent anti-rust kumanzi ashushu, uze ugalele umphunga ukuze wenze into yokuchasana nomhlwa idibane namanzi ize ibe ngumphunga ukuze yenze inkungu yamanzi.Ngale ndlela, amanzi anokuba yimeko ye-steam egcweleyo, kwaye emva kokunyangwa ngezixhobo zokulahla, injongo yokuphelisa okanye ukunciphisa ukubola kwezixhobo zetsimbi kunye nenkqubo yayo yokubhobhoza inokufezekiswa.
Iijeneretha ze-steam ze-industrial zenziwa ngobuchwepheshe obuphambili kunye neenkqubo ezikhethekileyo.Ineempawu zesakhiwo esincinci, ubungakanani obuncinci, ubunzima obulula, ingxolo ephantsi, ukusebenza okuzinzileyo, kunye nokusebenza ngokulula;kulula ukuyisebenzisa kwaye inokuthenjwa.
5. Amalungiselelo aneleyo kufuneka enziwe ngaphambi kokusetyenziswa ukuqinisekisa ukusetyenziswa okukhuselekileyo kunye neziphumo zokusebenza ezilungileyo.
Ijenereyitha yomphunga sisixhobo esinokufudumeza amanzi ukuba afuthaniseleke aze awafunxe.Ineempawu zesantya sokufudumeza ngokukhawuleza, amandla aphezulu, kunye nokusebenza okuphezulu kokhuseleko, kwaye inokwenza imisebenzi efana nokufudumeza, ukupholisa, kunye ne-crystallization yezinto eziluhlaza.Kwakhona kunomphumo wokucoca, okuyimpembelelo yokucoca isixhobo.Akunakukwazi ukunciphisa izixhobo kuphela, kodwa kwakhona ukucoca izixhobo, ukususa ngokufanelekileyo ukungcola ngaphakathi kwesixhobo, kunye nokwandisa ubomi benkonzo yezixhobo.
Iijenereyitha zomphunga zisetyenziswa kakhulu kwiikhemikhali, kumayeza, kukutya nakwamanye amashishini, kwaye zisetyenziswa ikakhulu ukujongana nokungcola, iioksidi kunye nezinye izinto eziyingozi kwizinto ezahlukeneyo ezikrwada kunye neemveliso ezigqityiweyo.
