I-biomass pellet fuel ukusetshenziswa "kodoti" ezitshalweni ezivunwa ezolimo. Imishini ye-biomass fuel pellet isebenzisa ngokuqondile utshani obubonakala bungenamsebenzi, sawdust, isikhwebu sombila, amakhoba elayisi, njll. ngokubunjwa kokucindezelwa. Indlela yokuguqula lezi mfucumfucu zibe ingcebo iwukudinga amaboilers kaphethiloli we-biomass briquette.

Isimiso sokusebenza se-biomass pellet mechanical fuel boiler compustion: uphethiloli we-biomass usakazwa ngokulinganayo ku-grate engaphezulu ukusuka esikhungweni sokuphakela noma engxenyeni engenhla. Ngemva kokuthungela, ifeni yokusalungiswa ekhangisiwe iyavulwa, ukuvuthuluka kukaphethiloli kuyahlaziywa, futhi ilangabi livutha libheke phansi. Indawo eyakhiwe yi-grate emisiwe ngokushesha yenza indawo yokushisa ephezulu, eyenza izimo zokuvutha okuqhubekayo nokuzinzile. Ngenkathi ivutha, iwela phansi, iwela ku-grate yokulenga ephezulu yokushisa isikhashana, bese iqhubeka nokuwa, futhi ekugcineni iwele ku-grate ephansi. Izinhlayiya zamafutha ezingaphelele ziyaqhubeka zivutha, futhi izinhlayiya zomlotha ezishisiwe zisuswa ku-grate engezansi. Khipha ku-ash hopper yedivayisi yokukhipha umlotha. Lapho ukuqoqwa komlotha kufinyelela ekuphakameni okuthile, vula isango lokukhipha umlotha bese ulikhipha ndawonye. Enqubweni yokuwa kukaphethiloli, indawo yesibili yokusatshalaliswa komoya yengeza inani elithile le-oxygen ukuze kushiswe ukumiswa, umoya-mpilo ohlinzekwa yisikhumulo sesithathu sokusatshalaliswa komoya usetshenziselwa ukusekela ukushiswa kwe-grate engezansi, futhi igesi eshisiwe ngokuphelele iholela indawo yokushisa ye-convection ngokusebenzisa i-flue gas outlet. . Lapho izinhlayiya ezinkulu zentuthu nothuli zidlulela phezulu ekwahlukaniseni, ziphonswa ku-ash hopper ngenxa ye-inertia. Uthuli oluncanyana luvinjwe inethi yokususa uthuli futhi iningi lazo liwela ku-ash hopper. Izinhlayiya ezithile ezinhle kakhulu kuphela ezingena endaweni yokushisa eguquguqukayo, okunciphisa kakhulu ukufudumeza kwe-convective. Ukuqoqwa kothuli ebusweni kuthuthukisa umphumela wokudlulisa ukushisa.
Izici zokushiswa kukaphethiloli okukhiqizwa yimishini ye-biomass pellet yilezi:

① Ingakha ngokushesha indawo yokushisa ephezulu, futhi igcine ngokuzinzile isimo sokusha esine-stratified, ukusha kwe-gasification kanye nokuvutha okumisiwe. I-flue gas ihlala esithandweni sokushisa okuphezulu isikhathi eside. Ngemuva kokusatshalaliswa komoyampilo kaningi, ukusha kwanele futhi izinga lokusebenzisa uphethiloli liphezulu, elingaxazululwa ngokuyisisekelo. Inkinga yentuthu emnyama.

②I-boiler efanayo inokugxiliswa okuphansi kokukhishwa kwensisi, ngakho-ke ushimula awudingeki.

③Uphethiloli uvutha ngokuqhubekayo, isimo sokusebenza sizinzile, futhi asithintwa ukwengezwa kukaphethiloli nomlilo, futhi okukhiphayo kungaqinisekiswa.

④Izinga eliphezulu lokuzenzakalela, umfutho ophansi wokusebenza, ukusebenza okulula nokulula, ngaphandle kwezinqubo zokusebenza eziyinkimbinkimbi.

⑤ Uphethiloli unokusebenza okubanzi futhi akukho slagging, okuxazulula inkinga yokwehla kalula kwezibaseli ze-biomass.

⑥ Ngenxa yokusetshenziswa kobuchwepheshe bomlilo bokuhlukanisa isigaba esiqinile segesi.

Futhi inezinzuzo ezilandelayo:

Izivunguvungu eziningi ezithunyelwa zisuka egumbini lokushisa eliphezulu le-pyrolysis kuya egumbini lokuvutha kwesigaba segesi zingama-hydrocarbon, alungele ukushiswa okuphansi komoya-mpilo noma okungaphansi komoya-mpilo, futhi angakwazi ukufeza ukushiswa kwentuthu emnyama, engacindezela ngempumelelo. isizukulwane se-"thermo-NO".

b Ngesikhathi senqubo ye-pyrolysis, isesimweni sokuntuleka komoya-mpilo, okungavimbela ngempumelelo i-nitrogen ekuphethiloli ukuthi ingaguqulwa ibe ama-nitrogen oxide anobuthi. Ukukhishwa okungcolile okuvela ekushisweni kwemishini kwama-pellets amafutha e-biomass ikakhulukazi inani elincane lezinto ezingcolisa umoya kanye nemfucumfucu eqinile engasetshenziswa ngokuphelele.
