Biomass Industrial IndustrialsUhlobo olulodwa lwe-biomass boiler esetshenziselwa ukukhiqizwa kwezimboni. Amafutha e-biomass anezinhlobo ezimbili: enye imfucumfucu ye-biomass enjengotshani bukatshani kanye notshani amagxolo, enye yi-pellet.

1. Inani lokushisa eliphansi likaphethiloli we-biomass lihlukile ngenxa yokuqukethwe okuhlukile komswakama, kuyilapho inani eliphakeme lokushisa liyafana. Amafutha aqoqiwe ngaphandle anokuqukethwe komswakama okusukela ku-12% kuya ku-45%.
2. Amafutha e-biomass anokuqukethwe okuphezulu okuguqukayo. I-Biomass Fuel iqala i-pyrolysis lapho izinga lokushisa lidlula ngo-170 ° C, 70% -80% we-turatele ndaba inembe, kufaka phakathi i-H2O, CO kanye CH4.
3. I-Biomass Fuel ayinawo amaphoyinti ahlehlisiwe ash incibilize. I-Al, FE, CA, MG kanye nezinye ezinye izinkabi emlotheni kukhulisa iphuzu lomlotha. Kodwa-ke, okuqukethwe okuphezulu k ne-NA kwenza iphuzu elincibilikisiwe lomlotha eliphansi kunaleso lamalahle.
I-4. I-Biomass Fuel Ash inobunzima obuphansi futhi kulula ukuthwalwa ngugesi we-flue. Ngaphezu kwalokho, ukuSlagging kulula ukwakha kwinqwaba yeshubhu elihlangenwe nakho, okuthinta umphumela wokudluliswa kokushisa.
I-5. Ubukhulu obuphelele bophethiloli we-biomass akujwayelekile.
II. Umklamo we-Biomass Boomass wezezimboni
1. Ukukhetha imishini yokuhlanganisa
I-grate yokubuyisela inezinzuzo ezisobala ngaphezulu kwe-chain grate ngosayizi kaphethiloli kanye nokuvuza kwamafutha. Ngakho-ke i-grate yokubuyisela iba yikhetho elifanelekile lemishini yokuvuselela ye-biomass ungqimba. I-grate ethambekele yokubuyisela umoya epholile
2. Design of feeding device
Ubuningi obuningi bophethiloli we-biomass bungama-200 kg / m3 kanti ubukhulu besendlalelo kaphethiloli bungaphezu kwama-20 cm. Ukushisa okusebenzayo kwesililo sikagesi phambi kwesithando somlilo ngeke kube ngaphansi kuka-150 ° C. Isango elivaliwe lisechwebeni lokudla. Ukwehliswa kwezinga lokushisa nokuvikelwa komlilo kungaba yijakhethi yokupholisa amanzi.
3. Idizayini yesithando somlilo
Ncoma ukuthi wamukele isakhiwo sensimbi esivalwe ngokugcwele, ipuleti yensimbi njengegobolondo elingaphandle, lifakwe umugqa okotini wokufakelwa kanye nezinto ezisindayo zokuphikisa. I-arch yangaphambili nangemuva kanye nezindonga eziseceleni kwesithando sezinto ezisindayo. Isikhathi sokuhlala igesi ephukile esithandweni somlilo sizoba okungenani ama-3m / s.
4. Ingxenye yokusatshalaliswa komoya
Umoya oyinhloko usuka engxenyeni engezansi ye-grate, futhi uhlukaniswe indawo yokuqala, indawo yokuhlanza, kanye nendawo ye-slag. Umoya wesibili uyabona ukuphazamiseka kokuhlanganiswa nokunikezwa komoya-mpilo.
Ivolumu yomoya eyinhloko izoba ngu-50% wevolumu yomoya ephelele. Umthamo womoya womoya wokuqala endaweni yokuhlanza imvelo kanye nendawo ye-slag yokupholisa ibha ye-grate. Umoya wesibili unezingxenye ezimbili, ukunikezela ngevolumu ama-akhawulela ama-akhawuntini akwa-20% kanye nokusabalalisa ama-akhawuntini angu-10% wevolumu yomoya ephelele. Ukugeleza komoya wokuhambisa umoya ngokuvamile kungu-40-60 m / s, futhi ingcindezi yabalandeli ngokuvamile ingu-4000 kuya ku-6000 PA.
I-5. Design of Heat Exchange Rice
I-Convection Tube Inqwaba izokwakhiwa ngezigaba, futhi igebe eliphakathi kweshubhu endaweni ephezulu yokushisa lizokwandiswa.
I-Biomass Industrial Boomars ivamile embonini yezinkuni, ihlinzeka ngamafutha ashisayo, umusi, umoya oshisayo wokukhiqiza ama-fiberboard aphakathi nendawo aphezulu.
