Dab tsi yog vim li cas rau qhov ua tsis tiav ntawm Biomass Pellet tsim?

Cov tshuab biomass pellet muaj peev xwm hloov tau ntau yam ntaub ntawv raw rau hauv high-density biomass pellet fuels. Txawm hais tias nws yog cov khoom siv ntoo xws li cov cav ntoo, sawdust, shavings, lossis cov khoom siv ua liaj ua teb xws li pob kws, nplej straw, thiab straw, lossis txawm tias cov khoom pov tseg xws li cov qauv tsim thiab cov khoom siv ntoo, lossis cov txiv hmab txiv ntoo, cov txiv hmab txiv ntoo residues, xim av aluminium, thiab sludge, lawv tuaj yeem raug pretreated thiab ua tiav, thiab tom qab ntawd hloov mus rau hauv high-density biomass pellet fuels los ntawm kev kho thiab extrusion txheej txheem ntawm biomass pellet tshuab. Cov roj no tsis tsuas yog muaj qhov zoo ntawm kev ua haujlwm siab thiab kev tiv thaiv ib puag ncig, tab sis kuj tseem siv tau ntau yam khoom siv pov tseg thiab paub txog kev rov ua dua ntawm cov peev txheej.

Cov khoom sib txawv muaj lawv tus kheej cov yam ntxwv thiab cov qauv fiber ntau, uas cuam tshuam ncaj qha rau qhov nyuaj ntawm kev kho lawv rau hauv pellets. Piv txwv li, cov txheej txheem pelletizing ntawm cov ntoo kuj tseem mos xws li ntoo thuv yog feem ntau smoother. Txawm li cas los xij, yog tias cov khoom siv raw nyuaj dhau los yog cov hmoov zoo li cov hmoov zoo, cov txheej txheem pelletizing yuav nyuaj, thiab cov khoom siv xws li ntoo shavings feem ntau yuav tsum tau ua. Tsis tas li ntawd, qhov sib xyaw ua ke ntawm cov khoom sib txawv kuj yog qhov tseem ceeb cuam tshuam rau kev tsim tus nqi, uas yuav tsum tau ua tib zoo kho kom ua tiav cov txiaj ntsig zoo tshaj plaws.

Thaum nias biomass pellets, cov dej noo ntawm cov khoom siv raw yog qhov tseem ceeb. Yog tias cov dej noo ntau dhau, cov pellets yuav tsis tshua muaj zog thiab yooj yim rau loosen; yog tias cov ntsiab lus noo noo tsawg dhau, nws yuav nyuaj rau tsim thiab yuav muaj hmoov ntau. Cov khoom sib txawv xws li ntoo thuv thiab fir muaj qhov sib txawv ntawm cov dej noo, tab sis feem ntau yuav tsum tau tswj hwm ntawm thaj tsam 15%. Cov ntsiab lus noo noo tshwj xeeb yuav tsum tau hloov kho raws li qhov tseeb tsim khoom kom ntseeg tau tias qhov ua haujlwm zoo tshaj plaws ntawm lub tshuab pellet.
