Biomass pellet roj yog siv "khoom pov tseg" hauv cov qoob loo ua liaj ua teb.Biomass roj pellet tshuab ncaj qha siv cov straw seemingly siv tsis tau, sawdust, pob kws, nplej husk, thiab lwm yam los ntawm compression molding.Txoj hauv kev los hloov cov khib nyiab no rau hauv cov khoom muaj nqis yog xav tau biomass briquette roj boilers.

Lub hauv paus ntsiab lus ua haujlwm ntawm biomass pellet mechanical fuel boiler combustion: biomass fuel is evenly spread on the upper grate from the feeding port or the upper part.Tom qab ignition, lub induced cua ntsawj ntshab kiv cua yog qhib, lub volatilization nyob rau hauv cov roj yog soj ntsuam, thiab cov nplaim taws kub hnyiab downward.Cov cheeb tsam tsim los ntawm cov grate raug tshem tawm sai sai ua rau thaj chaw kub siab, uas tsim cov xwm txheej rau kev siv hluav taws xob tas mus li thiab ruaj khov.Thaum kub hnyiab, nws ntog, ntog rau ntawm qhov kub-kub dai grate rau ib pliag, ces tseem poob, thiab thaum kawg poob rau ntawm qis grate.Cov roj hluav taws kub tsis tiav txuas ntxiv mus, thiab cov hluav taws kub hnyiab tau raug tshem tawm ntawm cov grate qis.Tshem tawm hauv cov hmoov tshauv hopper ntawm cov hmoov tshauv paug.Thaum cov hmoov tshauv nce mus txog qhov siab, qhib lub rooj vag tshauv tawm thiab tso tawm ua ke.Nyob rau hauv cov txheej txheem ntawm cov roj poob, qhov chaw nres nkoj cua thib ob ntxiv cov pa oxygen rau kev ncua kev sib txuas, cov pa oxygen muab los ntawm qhov chaw nres nkoj cua thib peb yog siv los txhawb kev sib txuas ntawm cov grate qis, thiab cov roj hlawv tag ua rau convection cua sov nto los ntawm lub qhov hluav taws xob flue..Thaum cov pa taws loj thiab cov plua plav dhau los ntawm qhov muab faib, lawv raug pov rau hauv cov tshauv hopper vim inertia.Cov plua plav me me yog thaiv los ntawm cov plua plav tshem tawm baffle net thiab feem ntau ntawm lawv poob rau hauv cov tshauv hopper.Tsuas yog qee cov khoom zoo heev nkag mus rau qhov chaw cua sov, uas txo cov cua sov zoo heev.Cov plua plav tsub zuj zuj ntawm qhov chaw txhim kho cov nyhuv hloov tshav kub.
Cov yam ntxwv ntawm cov roj combustion ua los ntawm biomass pellet machinery yog:

① Nws tuaj yeem tsim qhov chaw kub kub sai, thiab ruaj khov tswj lub xeev ntawm stratified combustion, gasification combustion thiab tshem tawm combustion.Cov pa roj flue nyob twj ywm hauv qhov kub kub rau lub sijhawm ntev.Tom qab ntau qhov kev faib tawm ntawm cov pa oxygen, qhov kev sib txuas yog txaus thiab cov roj siv tau siab, uas tuaj yeem daws qhov teeb meem.Teeb meem haus luam yeeb dub.

② Lub boiler sib xws muaj qis thawj concentration ntawm soot emission, yog li lub chimney tsis xav tau.

③ Cov roj hlawv tsis tu ncua, kev ua haujlwm ruaj khov, thiab tsis cuam tshuam los ntawm kev sib ntxiv ntawm cov roj thiab hluav taws, thiab cov zis tuaj yeem lav tau.

④High degree ntawm automation, kev siv zog tsawg, kev ua haujlwm yooj yim thiab yooj yim, tsis muaj cov txheej txheem ua haujlwm nyuaj.

⑤ Cov roj muaj kev siv dav thiab tsis muaj slagging, uas daws qhov teeb meem ntawm kev yooj yim slagging ntawm biomass fuels.

⑥ Vim yog siv cov pa roj-khoom sib cais combustion tshuab.

Nws kuj muaj qhov zoo hauv qab no:

Feem ntau ntawm cov volatiles xa los ntawm high-temperature pyrolysis combustion chamber mus rau lub gas-theem combustion chamber yog hydrocarbons, uas yog haum rau tsawg tshaj-oxygen los yog under-oxygen combustion, thiab muaj peev xwm ua tsis tau cov pa taws dub combustion, uas yuav ua tau zoo suppress tiam ntawm "thermo-NO".

b Thaum lub sij hawm cov txheej txheem pyrolysis, nws yog nyob rau hauv lub xeev tsis muaj oxygen, uas tuaj yeem tiv thaiv cov nitrogen hauv cov roj los ntawm kev hloov mus rau cov tshuaj lom nitrogen oxides.Cov pa phem emissions los ntawm cov neeg kho tshuab combustion ntawm biomass roj pellets feem ntau yog ib qho me me ntawm cov pa phem thiab cov khoom khib nyiab uas tuaj yeem siv tau.
