Isikali sisongela ngokuthe ngqo ukhuseleko kunye nobomi benkonzo yesixhobo se-steam generator kuba i-thermal conductivity yesikali incinci kakhulu.I-thermal conductivity yesikali ngamakhulu amaxesha amancinci kuneentsimbi.Ke ngoko, nokuba isikali asingqindilili kakhulu senziwe kwindawo yokufudumeza, ukusebenza kakuhle kokuqhuba ubushushu kuya kuncitshiswa ngenxa yokuxhathisa okukhulu kwe-thermal, okukhokelela ekulahlekeni kobushushu kunye nenkcitho yamafutha.
Uqheliselo lubonakalise ukuba i-1mm yesikali kumphezulu wokufudumeza wejenereyitha yomphunga inokunyusa ukusetyenziswa kwamalahle malunga ne-1.5 ~ 2%.Ngenxa yesikali kwindawo yokufudumala, udonga lombhobho wensimbi luya kugqithiswa ngokuyinxenye.Xa iqondo lokushisa eludongeni lidlula iqondo lokushisa elivumelekileyo lokusebenza, umbhobho uya kuqhuma, onokuthi ubangele ingozi yokuqhuma kombhobho kwaye isongele ukhuseleko lomntu.Isikali yityuwa entsonkothileyo equkethe i-halogen ion edla intsimbi kumaqondo obushushu aphezulu.
Ngokuhlalutya kwesikali sentsimbi, kunokubonwa ukuba umxholo wayo wentsimbi umalunga ne-20 ~ 30%.Ukukhukuliseka komlinganiselo wesinyithi kuya kubangela ukuba udonga lwangaphakathi lwejenereyitha yomphunga lube brittle kwaye ludle ngokunzulu.Ngenxa yokuba ukususa isikali kufuna ukuvala isithando somlilo, kudla amandla abantu kunye nezinto eziphathekayo, kwaye kubangela umonakalo womatshini kunye nokubola kweekhemikhali.
Ijenereyitha yomphunga yeNobeth inesixhobo sokujonga isikali esizenzekelayo kunye nesixhobo se-alam.Ilinganisa ukulinganisa eludongeni lombhobho ngokubeka iliso ekuphumeni kobushushu bomzimba.Xa kukho ukukala okuncinci ngaphakathi kwibhoyila, iya kuzikhathaza ngokuzenzekelayo.Xa ukulinganisa kunzima, kuya kunyanzeliswa ukuba kuvalwe ukuphepha ukulinganisa.Umngcipheko wokugqabhuka kombhobho ngcono wandisa ubomi benkonzo yesixhobo.
1. Mechanical descaling method
Xa kukho isikali okanye i-slag kwisithando somlilo, cima amanzi esithandweni emva kokuvala isithando somlilo ukupholisa i-generator ye-steam, uze uyihlambe ngamanzi okanye usebenzise ibrashi yocingo olujikelezayo ukuyisusa.Ukuba isikali sinzima kakhulu, sinokucocwa ngehagu yombhobho eqhutywa luxinzelelo oluphezulu lwejethi yamanzi okanye amandla ombane.Le ndlela ifanelekile kuphela ukucoca imibhobho yetsimbi kwaye ayifanelekanga ukucoca imibhobho yobhedu kuba umcoci wepayipi unokonakalisa ngokulula imibhobho yobhedu.
2. Indlela eqhelekileyo yokususa isikali seekhemikhali
Ngokwezinto eziphathekayo zezixhobo, khetha i-arhente yokucoca ekhuselekileyo kunye nenamandla.Ngokuqhelekileyo, ukugxininiswa kwesisombululo kulawulwa kwi-5 ~ 20%, enokuthi ikwazi ukumiselwa ngokobunzima bomlinganiselo.Emva kokucoca, qala ukhulule i-liquid enkunkuma, uze uhlambulule ngamanzi acocekileyo, uze ugcwalise amanzi, ungeze i-neutralizer malunga ne-3% yomthamo wamanzi, udibanise kwaye ubilise iiyure ezingama-0.51, emva kokukhulula i-liquid eseleyo, hlambulula kanye okanye kabini. ngamanzi acocekileyo.
Ukwakhiwa kwesikali kwijenereyitha yomphunga kuyingozi kakhulu.Ukukhutshwa rhoqo kunye nokunciphisa kuyafuneka ukuze kuqinisekiswe ukusebenza okuqhelekileyo kwejeneretha ye-steam.
