Biomass yog cov organic uas tuaj yeem siv los tsim lub zog. Nws tuaj yeem suav nrog ntoo, cov ntaub ntawv cog thiab txawm tias tsiaj dung, siv los tua hluav taws kom sov thiab ua noj.
Txawm li cas los xij, los ntawm compressing organic teeb meem xws li ntoo, hav zoov residues thiab sawdust rau hauv lub zog-dense pellets, biomass yuav siv tau rau cua sov los yog tauj dua tshiab bioenergy tiam ntawm ib tug ntau dua scale.
Vim li cas cov pellets muaj zog?
Qhov zoo ntawm kev siv biomass nyob rau hauv daim ntawv ntawm pellet yog nws lub zog ceev. Qhov no yog hais txog tus nqi ntawm lub zog uas tuaj yeem khaws cia hauv ib qho khoom siv.
Ntawm lawv tus kheej cov ntoo thiab cov seem zoo li ntoo chips thiab sawdust uas ua rau biomass tsis muaj lub zog loj. Ib kilogram ntawm ntoo, piv txwv li, khaws lub zog me me, piv rau cov roj xws li thee, diesel lossis uranium.
Txawm li cas los xij, los ntawm compressing hav zoov kev lag luam residues rau hauv ib lub pellet, biomass ua zog ntau zog. Ntoo pellets tseem tuaj yeem muaj cov ntsiab lus tsis tshua muaj dej noo, ua rau lawv muaj kev sib xyaw ua haujlwm siab - ib qho tseem ceeb hauv kev tsim hluav taws xob.
Yuav ua li cas biomass pellets ua?
Biomass pellets yog tsim los ntawmib tsob nroj pelletization. Ntawm no cov ntoo uas tsis tsim nyog rau lwm cov lag luam xws li sawmill seem, raug coj los ua ke.
Cov ntoo yog chipped, tshuaj xyuas kom zoo, rhuab kom txo nws cov dej noo kom qis dua 12 feem pua thiab tom qab ntawd hloov mus rau hauv cov hmoov zoo. Qhov no yog ces nias los ntawm grate ntawm kev kub siab los tsim cov khoom, luv luv, ntom biomass pellet.
Yuav siv cov pellets li cas hauv kev tsim hluav taws xob?
Biomass pellets tuaj yeem siv los tsim hluav taws xob zoo ib yam li cov thee, tso caicov chaw siv hluav taws xob uas twb muaj lawm los hloov pauv mus siv bioenergy tauj dua tshiabxwb.
Lub conveyor system siv pellets los ntawm kev cia mus raupulverizing mills, qhov twg lawv raug crushed rau hauv ib tug nplua hmoov uas yog ces tshuab mus rau hauv lub hwj chim chaw nres tsheb boiler. Ntawm no cov biomass yog combusted li roj, lub tshav kub los ntawm no combustion yog siv los uasteam uas powers lub generatorsuas tsim hluav taws xob.
Biomass pellets 'density thiab uniform shape kuj ua rau lawvyooj yim rau kev thauj mus losthiab khaws cia rau hauv qhov ntau. Txawm li cas los xij, nws yog ib qho tseem ceeb uas lawv khaws cia qhuav thaum nyob hauv kev thauj mus los thiab thaum khaws cia hauv biomass domesatmospheric tej yam kev mob yog ua tib zoo saib xyuas thiab tswjlos tiv thaiv pliaj combustion.
Biomass pellet qhov tseeb
Biomass pellets tsim80 feem pua CO2emissions thaum combusted tshaj thee, nrog rau qis qis ntawm sulphur, chlorine, nitrogen.
Ntoo pellets muaj zog ceev ntawm 11 gigajoules / m3, piv rau 3 gigajoules / m3 los ntawm cov ntoo tshiab los yog ntoo chips,raws li International Renewable Energy Agency(IRENA).
Ntiaj teb no ntoo pellet noj rau cua sov, nrog rau lub hwj chim, mus txog35 lab tons hauv 2018- tsis suav nrog Suav teb.
Thaum siv nyob rau hauv high-efficiency ntoo pellet qhov cub thiab boilers, biomass pellets muaj peev xwm muab taucombustion efficiency siab li 85 feem pua.
Puas yog biomass pellets txuas ntxiv tau?
Thaum hav zoov muaj kev tswj xyuas kom ruaj khov, thiab cov ntoo ib txwm rov tsim dua lossis rov cog dua thiab rov loj hlob nyob rau hauv tib neeg lub sijhawm, nws ua rau biomass pellets tau los ntawm lawv txuas ntxiv.
Nws yog ib qho tseem ceeb rau lub sij hawm ntev lub zog tiam uas biomass pellets yog los ntawmlub luag hauj lwm tswj hav zoovthiab lwm yam kev lag luam uas tiv thaiv ib puag ncig thiab tsis ua rau deforestation. Kev txiav txim siab yuav tsum yog science-based thiab tsis cuam tshuam rau lub sijhawm ntev ntawm cov hav zoov khaws cia thiab khaws cov pa roj carbon monoxide.
Sustainable ntoo pellets raug suav hais tias yog cov pa roj carbon nruab nrab ntawm qhov chaw ntawm combustion. Thaum lawv loj hlob, hav zoov nqus cov pa roj carbon monoxide los ntawm huab cua. Thaum ib tug biomass pellet yog combusted, tib tus nqi ntawm atmospheric CO2tso tawm. Tus nqi tag nrho ntawm CO2nyob rau hauv cov huab cua tseem nyob nruab nrab, tsis zoo li nrog fossil fuels uas tso cov pa roj carbon monoxide uas tau ntev poob tawm ntawm lub voj voog ntuj.
Vim hais tias kev ruaj ntseg bioenergy yog cov pa roj carbon tsawg thaum nws lub neej emissions, suav nrog cov saw hlau CO2, yog factored nyob rau hauv, nws muaj peev xwm tig nws mus rau hauv ib qhov chaw ntawm tsis zoo emissions, nrog rau ntxiv ntawmcarbon capture technology.
