Ukwelashwa kwamanzi kubhayela we-steam

Incazelo emfushane:

Ingozi ye-steam generator grate slagging
I-slagging ye-biomass steam generator akugcini nje ukwandisa umthwalo wokusebenza kwe-boiler, ukugcinwa nokulungiswa, kubeka engcupheni ukuphepha nokusebenza kwezomnotho, kodwa futhi kungase kuphoqe isithando somlilo ukunciphisa umthwalo noma ngisho nokuphoqeleka ukuvala. I-slagging ngokwayo iyinqubo eyinkimbinkimbi yomzimba kanye namakhemikhali, ebuye ibe nezici zokuziqinisa. Uma i-boiler i-slagging, ngenxa yokumelana okushisayo kwesendlalelo se-slag, ukudluliswa kokushisa kuzokwehla, futhi izinga lokushisa emphinjeni wesithando somlilo kanye nobuso bengqimba ye-slag kuzokwanda. Ngaphezu kwalokho, ubuso be-slag layer bunzima, futhi izinhlayiya ze-slag zivame ukunamathela, okuholela enkambisweni ye-slagging enamandla kakhulu. Ngezansi kunohlu olufushane lwezingozi ezibangelwa ukuqhuma kwe-steam generator.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

1. I-slagging ku-nozzle yokushisa ishintsha isakhiwo sokugeleza komoya endaweni yokukhipha ukushisa, ibhubhisa izimo ze-aerodynamic esithandweni, futhi ithinte inqubo yomlilo. Lapho i-nozzle ivimbelwe kakhulu ngenxa ye-slagging, i-boiler ye-steam kufanele isetshenziswe ngomthwalo owehlisiwe noma iphoqelelwe ukuvala.
2. I-slagging odongeni olupholile ngamanzi kuzoholela ekushiseni okungalingani kwezingxenye zomuntu ngamunye, okuzoba nomthelela omubi ekuphepheni komjikelezo wamanzi wokujikeleza kwemvelo kanye nokuphambuka okushisayo kodonga olulawulwa ngamanzi olupholile, futhi kungenzeka. dala umonakalo kumapayipi odongeni apholise amanzi.
3. Ukwehliswa endaweni yokushisa kuzokhuphula ukumelana nokushisa, kwenze kube buthaka ukudluliswa kokushisa, kunciphise ukumuncwa kokushisa koketshezi olusebenzayo, kukhuphule izinga lokushisa lokukhipha umoya, kwandise ukulahlekelwa ukushisa kwe-exhaust, futhi kunciphise ukusebenza kahle kwebhayela. Ukuze kugcinwe ukusebenza okujwayelekile kwe-boiler, kuyadingeka ukwandisa inani lomoya ngenkathi ukwandisa inani likaphethiloli, okwandisa umthwalo ku-blower kanye ne-draft fan fan, futhi kwandise ukusetshenziswa kwamandla asizayo. Ngakho-ke, i-slagging inciphisa kakhulu ukusebenza kahle kwezomnotho kokusebenza kwe-steam boiler.
4. Uma i-slagging ivela endaweni yokushisa, ukuze kugcinwe ukusebenza okujwayelekile kwejeneretha ye-steam, kuyadingeka ukwandisa umthamo womoya. Uma umthamo wemishini yokungenisa umoya ulinganiselwe, kuhlanganiswe ne-slagging, kulula ukubangela ukuvinjelwa okuyingxenye kwe-flue gas passage, ukwandisa ukumelana kwegesi ye-flue, futhi kube nzima ukwandisa umthamo womoya we-fan, ngakho-ke kufanele kuphoqeleke ukunciphisa ukusebenza komthwalo.
5. Ngemuva kwe-slagging endaweni yokushisa, izinga lokushisa legesi ye-flue endaweni yokukhipha isithando somlilo liyakhuphuka, okuholela ekwandeni kwezinga lokushisa elishisa kakhulu. Ngaphezu kwalokho, ukuchezuka kokushisa okubangelwa i-slagging kungabangela kalula umonakalo oshisayo ku-superheater. Ngalesi sikhathi, ukuze kugcinwe izinga lokushisa elishisayo futhi uvikele i-reheater, kuyadingeka futhi ukunciphisa umthwalo ngesikhathi sokuzivocavoca.
