Ukubilisa isitofu kungenye inqubo okufanele yenziwe ngaphambi kokuba kusetshenziswe imishini emisha. Ngokubilisa, ukungcola nokugqwala okusele kusigubhu sejeneretha yesitimu segesi phakathi nenqubo yokukhiqiza kungasuswa, kuqinisekiswe ikhwalithi yesitimu nokuhlanzeka kwamanzi lapho abasebenzisi bewusebenzisa. Indlela yokubilisa i-gas steam generator imi kanje:
(1) Indlela yokupheka isitofu
1. Phakamisa umlilo omncane esithandweni bese ubilisa kancane amanzi ebhodweni. I-steam ekhiqizwayo ingakhishwa nge-valve yomoya noma i-valve yokuphepha ephakanyisiwe.
2. Lungisa ukuvulwa kwevalvu evuthayo neyomoya (noma i-valve yokuphepha). Gcina i-boiler ku-25% ingcindezi yokusebenza (6-12h ngaphansi kwesimo se-5% -10% ukuhwamuka). Uma ihhavini iphekwe ngesikhathi esifanayo esigabeni sakamuva sehhavini, isikhathi sokupheka singancishiswa ngokufanele.
3. Yehlisa iziqhumane, yehlisa ingcindezi ebhodweni ibe ngu-0.1MPa, khipha indle njalo, futhi ugcwalise amanzi noma wengeze isixazululo somuthi esingaqediwe.
4. Khulisa i-firepower, phakamisa ingcindezi ebhodweni ibe ngu-50% wengcindezi yokusebenza, futhi ugcine ukuhwamuka kuka-5% -10% amahora angu-6-20.
5. Bese wehlisa iziqhumane ukuze unciphise ingcindezi, khipha ama-valve endle ngalinye ngalinye, bese ugcwalisa amanzi.
6. Phakamisa ukucindezela ebhodweni ku-75% wengcindezi yokusebenza futhi ugcine ukuhwamuka okungu-5% -10% amahora angu-6-20.
Ngesikhathi sokubilisa, izinga lamanzi ku-boiler kufanele lilawulwe ezingeni eliphezulu kakhulu. Lapho izinga lamanzi lehla, amanzi kufanele agcwaliswe ngesikhathi. Ukuze kuqinisekiswe ukusebenza kahle kwe-boiler, amanzi ebhodwe kufanele athathwe ezigubhini ezingaphezulu neziphansi kanye namaphuzu okuthuthwa kwendle ekhanda ngalinye njalo ngamahora angu-3-4, futhi okuqukethwe kwe-alkalinity ne-phosphate emanzini ebhodwe kufanele kuhlaziywe. Uma umehluko mkhulu kakhulu, i-drainage ingasetshenziswa Yenza izinguquko. Uma i-alkalinity yamanzi ebhodweni ingaphansi kuka-1mmol/L, umuthi owengeziwe kufanele wengezwe ebhodweni.
(2) Amazinga okupheka izitofu
Lapho okuqukethwe kwe-trisodium phosphate kuvame ukuzinza, kusho ukuthi ukusabela kwamakhemikhali phakathi kwamakhemikhali emanzini ebhodwe kanye nokugqwala, isikali, njll. endaweni engaphakathi kubhayela sekuphelile, futhi ukubilisa kungaqedwa.
Ngemva kokubilisa, cisha umlilo osele esithandweni somlilo, khipha amanzi ebhodweni ngemva kokuba selipholile, futhi ukhuhle ingaphakathi likabhayela uhlanze ngamanzi ahlanzekile. Kuyadingeka ukuvimbela isisombululo esiphezulu se-alkalinity esisele ku-boiler ukuthi singabangeli igwebu emanzini asebhoyili futhi sithinte ikhwalithi ye-steam ngemva kokufakwa kwe-boiler. Ngemva kokukhuhla, izindonga zangaphakathi zesigubhu kanye nesihloko kudingeka zihlolwe ukuze kukhishwe ukungcola ngokuphelele. Ikakhulukazi, i-valve yokukhipha amanzi kanye negeji yezinga lamanzi kufanele ihlolwe ngokucophelela ukuze kuvinjwe inzika ekhiqizwa phakathi nokubilisa.
Ngemuva kokudlulisa ukuhlolwa, engeza amanzi ebhodweni futhi bese uphakamisa umlilo ukuze ufake i-boiler ekusebenzeni okujwayelekile.
(3) Izinyathelo zokuqapha lapho upheka isitofu
1. Akuvunyelwe ukwengeza izidakamizwa eziqinile ngqo kubhayela. Lapho ulungiselela noma wengeza izixazululo zezidakamizwa kubhayela, umqhubi kufanele agqoke izinto zokuzivikela.
2. Kuma-boilers anama-superheaters, amanzi ane-alkali kufanele avinjwe ukuthi angangeni ku-heater;
3. Umsebenzi wokuphakamisa umlilo kanye nokuphakamisa ingcindezi ngesikhathi sokubilisa kufanele ulandele imithethonqubo ehlukahlukene kanye nokulandelana kokusebenza phakathi nenqubo yokukhuphula umlilo kanye nenqubo yokukhulisa umfutho lapho ubhayela usebenza (njengokusula igeji yezinga lamanzi, ukuqinisa imigodi kanye nembobo yesandla. izikulufu, njll.).
