Ukubilisa isitovu yenye inkqubo ekufuneka yenziwe phambi kokuba kusetyenziswe isixhobo esitsha. Ngokubilisa, ukungcola kunye ne-rust esele kwi-drum ye-gas generator ye-steam ngexesha lenkqubo yokuvelisa inokususwa, iqinisekisa umgangatho we-steam kunye nokucoceka kwamanzi xa abasebenzisi beyisebenzisa. Indlela yokubilisa ijenereyitha yomphunga ilandelayo:
(1) Indlela yokupheka isitovu
1. Phakamisa umlilo omncinane eziko kwaye kancinane ubilise amanzi embizeni. Umphunga owenziweyo unokukhutshwa ngevalve yomoya okanye ivelufa yokhuseleko ephakanyisiweyo.
2. Lungisa ukuvulwa kwevalve yokutsha kunye nomoya (okanye ivalve yokhuseleko). Gcina ibhoyili kwi-25% yoxinzelelo olusebenzayo (6-12h phantsi kwemeko ye-5% -10% evaporation). Ukuba i-oven iphekwe ngexesha elifanayo kwinqanaba lokugqibela le-oven, ixesha lokupheka lingancitshiswa ngokufanelekileyo.
3. Nciphisa i-firepower, ukunciphisa uxinzelelo embizeni ukuya kwi-0.1MPa, khupha i-lindle rhoqo, kwaye uzalise amanzi okanye ungeze isisombululo esingagqitywanga samayeza.
4. Ukwandisa i-firepower, phakamisa uxinzelelo ebhodweni ukuya kwi-50% yoxinzelelo olusebenzayo, kwaye ugcine i-5% -10% evaporation kwiiyure ezingama-6-20.
5. Emva koko unciphise i-firepower ukunciphisa uxinzelelo, khupha iivalve ze-lindle nganye nganye, kwaye uzalise ukunikezelwa kwamanzi.
6. Phakamisa uxinzelelo ebhodweni ukuya kwi-75% yoxinzelelo lokusebenza kwaye ugcine i-5% -10% ye-evaporation kwiiyure ezingama-6-20.
Ngexesha lokubilisa, umgangatho wamanzi webhoyili kufuneka ulawulwe kwinqanaba eliphezulu. Xa umgangatho wamanzi uhla, ukunikezelwa kwamanzi kufuneka kuzaliswe kwakhona ngexesha. Ukuze kuqinisekiswe ukusebenza kakuhle kwebhoyila, amanzi embiza kufuneka athathwe kwimigqomo ephezulu nangaphantsi kunye neendawo zokulahla ugutyulo lwentloko nganye kwiiyure ezi-3-4, kunye nomxholo we-alkalinity kunye nephosphate yamanzi embizeni kufuneka ihlalutywe. Ukuba umahluko mkhulu kakhulu, i-drainage ingasetyenziswa Yenza uhlengahlengiso. Ukuba i-alkalinity yamanzi embizeni ingaphantsi kwe-1mmol / L, iyeza elongezelelweyo kufuneka lifakwe embizeni.
(2) Imigangatho yezitovu zokupheka
Xa umxholo we-trisodium phosphate uthande ukuzinza, oko kuthetha ukuba ukusabela kweekhemikhali phakathi kweekhemikhali emanzini ebhodweni kunye nomhlwa, isikali, njl. kwindawo engaphakathi kwibhoyila iphelile, kwaye ukubilisa kunokugqitywa.
Emva kokubilisa, cima umlilo oseleyo eziko, cima amanzi embizeni emva kokuba ipholile, kwaye ukhuhle ngaphakathi kwibhoyila ucoce ngamanzi acocekileyo. Kuyimfuneko ukukhusela isisombululo esiphezulu se-alkalinity eseleyo kwibhoyila ekubangeleni i-foam kwi-bhoiler yamanzi kunye nokuchaphazela umgangatho we-steam emva kokuba ibhoyili isetyenziswe. Emva kokuxubha, iindonga zangaphakathi zomgqomo kunye nentloko kufuneka zihlolwe ukuze zisuse ngokupheleleyo ukungcola. Ngokukodwa, ivalve yokukhupha amanzi kunye negeyiji yomgangatho wamanzi kufuneka ihlolwe ngononophelo ukuthintela intlenga eveliswa ngexesha lokubilisa.
Emva kokuphumelela uhlolo, yongeza amanzi embizeni kwakhona kwaye uphakamise umlilo ukubeka ibhoyila ekusebenzeni okuqhelekileyo.
(3) Izilumkiso xa upheka isitovu
1. Akuvumelekanga ukongeza iziyobisi eziqinileyo ngqo kwibhoyili. Xa ulungiselela okanye ukongeza izisombululo zeziyobisi kwibhoyila, umqhubi kufuneka anxibe izixhobo zokukhusela.
2. Kwiibhoyili ezinee-superheaters, amanzi e-alkaline kufuneka athintelwe ekungeneni kwi-superheater;
3. Umsebenzi wokunyusa umlilo kunye nokunyusa uxinzelelo ngexesha lokubilisa kufuneka ulandele imimiselo eyahlukeneyo kunye nolandelelwano lokusebenza ngexesha lokunyusa umlilo kunye nenkqubo yokunyusa uxinzelelo xa ibhoyila isebenza (njengokugungxula i-gauge yomgangatho wamanzi, ukuqinisa imingxuma kunye nomngxuma wesandla. izikrufu, njalo njalo).
