I-Boiler ye-Brate Ephindaphindayo kungenye igama elibuyisela ama-boiler we-grate. Njenge-boomass boiler, boiler e-borte ephindayo ilungele uthuli lwezinkuni oluvuthayo, utshani, i-bagasse, i-fiber yesundu, irayisi husk. I-Biomass Fuel iyi-petrol evuselelekayo, enesibabule esincane kanye nomlotha, kanye nokuphuma okuncane kanye nothuli.
Kunezinhlobo eziningi zikaphethiloli we-biomass, kufaka phakathi uhlobo lwe-pellet, uhlobo lwe-briquette kanye nohlobo lweningi. Ukungcola kusuka esitshalweni sokucubungula izinkuni, njengegxolo kanye ne-sawdust, kuvame ukusetshenziselwa uhlobo lweningi. Kodwa-ke, umswakama wemfucuza ngu-50% noma ngaphezulu, futhi inani le-calorific liphansi kakhulu. Ngakho-ke kunzima ukuyishisa ngempumelelo nge-biomass boomass boiler. Ngakho-ke, sakha i-boiler ehlanganisiwe ehlanganisiwe enama-engeli ahlukahlukene athambekele. I-biolir entsha ye-biomass ingahle ivumelane nokuhlanganiswa kwe-biomass fuel enoMswakama Ophakeme kanye nenani eliphansi lokushisa.
1.Disini uphethiloli
Lokhu kubuyisela i-boiler ye-grate yenzelwe ngokukhethekile isitshalo sokucubungula izinkuni. Umsebenzisi udinga ukushisa ama-200tons Wood Ukungcola kokhuni ngosuku ukukhiqiza i-1.25MPA Steate Steated yenqubo yokukhiqiza. Umphumela wokuhlaziywa kwengxenye ye-Wood Wast kanjena:
Umswakama Ophelele: 55%
I-Carbon: 22.87%
I-Hydrogen: 2.41%
I-oksijini: 17.67%
I-Nitrogen: 0.95%
Isibabule: 0.09%
I-Ash: 1.01%
Indaba Eguquguqukayo: 76.8%
Inani eliphansi lokushisa: 7291kj / kg
Ngemuva kokubala okulinganiselwe kwe-thermal, ama-200tons ngosuku lokushiswa ngokhuni oluvuthayo angakhiqiza cishe i-20T / H 1.25MPA Steateted Steate. Imfucuza yezinkuni idinga ukwelashwa kwangaphambi, futhi usayizi wokugcina ngeke weqe ama-350 * 35 * 35mm.

3. Isakhiwo sonke
I-boiler e-rectimpOCAL i-boiler yamukela ukujikeleza komoya omncane okuvundlile okuvundlile, kanye nesithando somlilo kusekwe phansi kusekelwa phezulu.
Uma kucatshangelwa umswakama omkhulu kanye nenani eliphansi le-calorific, idivaysi yokuvuselela i-admate ihlanganisa i-ondote ehlanganisiwe enama-engeli amabili athambekele.
I-bood boiler yamukela ukwakheka kwengqimba eyodwa. I-Slag Remover ingaphansi kokuphakama kwamamitha ayi-0, futhi ungqimba lokusebenza lusekuphakameni kwamamitha ayi-0. Isakhiwo sohlelo silula, esisindisa izindleko zomphakathi ngezinga elikhulu kakhulu.
4. Iphuzu Design
4.1 Idivaysi yokuhlanganisa
I-grate ihlukaniswe izigaba ezimbili ngama-engeli ahlukile athambekele. Ingxenye yangaphambili iyisigaba sokuqala kanye nesigaba sokomiswa esine-32 ° Isinyathelo. Ingxenye engemuva ingukuhlanganiswa okuyinhloko nesigaba esishisayo esine-10 ° Isinyathelo i-grate.
Lapho uphethiloli ungena esithandweni somthakathi, uwela ngaphambili kwesinyathelo esingu-32 °. Iqhutshwa yi-grate eshukumisayo, uphethiloli uzoqhamuka kusuka phezulu kuya phansi ngenkathi udlulela esithandweni somlilo. Ngakho-ke kuwusizo ekuxubeni komoya oshisayo ngophethiloli. Ngaleso sikhathi, uphethiloli ukhishwe ngokuphelele ngesithando somlilo ngenkathi usondela phambili, okuwusizo ekumeni komswakama. Ngakho-ke, uphethiloli ungamiswa ngokuphelele esigabeni sesinyathelo esingu-32 °. Uphethiloli omisiwe ungena kwi-threte ye-10 ° 10 °. Ngaphansi kokucindezela kwe-grate eshukumisayo, uphethiloli uqhubekela phambili ngokuqhubekayo futhi ukhiqiza ukunyakaza okuhlobene, ukuze uphethiloli uhlanganiswe ngokuphelele nomoya wokuqala. Ukuhlanganiswa kanye nenqubo yokushiswa kuqediwe ngaphansi kwemisebe eqhubekayo ye-arch engemuva.
4.2 Ukuphakelwa kwedivayisi
Udonga lwangaphambili lunamadivayisi amabili okuphakelayo anengxenye ye-inlet we-1 * 0.5m. Phansi kwedivayisi yokudla kunepuleti eliguqukayo eliguqukayo, lapho umoya wokutshala imbewu. Lapho ushintsha i-angle phakathi kwepuleti yokulungiswa nendiza evundlile, iphuzu lokuphonsa ku-grate lingashintshwa. I-pureless Double Spiral feer ihlelwe phambi kwensiza ngayinye yokuphakelayo, engenayo i-shaft ephakathi, ngaleyo ndlela igweme ukuvela kwamafutha aguqukayo emgodini ovunguzayo.
4.3 umoya oyinhloko nowesibili
Kubekwe amasethi amathathu endabuko yesibili esithandweni. Umoya wesibili endaweni yokuphuma kwe-arver arch ingakhuthaza ukuxutshwa okugcwele kwegesi kanye nomoya, futhi ucindezele igesi ephezulu yokushisa igesi ku-arch yangaphambili ukwenza lula ukwenziwa komsebenzi, ukomisa nokulahla uphethiloli. Umoya wesibili ohlelwe ngenhla kwetheku lokudla ungavuselela uhlanganise igesi ebibangelo kusuka engxenyeni engezansi yesithando somlilo, futhi unikeze umoya owanele ukwenza ngcono ukusebenza kahle kwe-. I-duct yomoya ngasinye sesibili ilawulwa yi-mamper, engaguqula ivolumu yomoya ngokwesimo sokuvutha. Ingxenye engezansi ye-grate ihlukaniswe ngamagumbi amaningi endiza, ihlinzeka ngomoya ophambili ngophethiloli futhi ipholise i-grate.
4.4 indawo yokushisa enomqondo
Inqwaba yeshubhu le-convection ilungiselelo le-in-line, i-Economizer ayilungiselelo le-truire in-line i-inthanethi, futhi i-air Preseater ilungiselelo le-in-line. Ukugwema ukugqwala okushisa okuphansi, ipayipi le-air Preseater liyipayipi lokuhlanza ingilazi. Ama-Shoove wave soot ama-soot afakwe endaweni ngayinye yokufudumeza ngokushisa ukuze anciphise ukufakwa kwe-ASH.
5. Umphumela Wokusebenza
