Tsis muaj teeb meem dab tsi uas koj tau npaj: yuav ntoo pellets lossis tsim ntoo pellet ntoo, nws yog ib qho tseem ceeb rau koj kom paub tias cov ntoo ntoo yog qhov twg zoo thiab qhov tsis zoo. Ua tsaug rau kev tsim kho kev lag luam, muaj ntau dua 1 ntoo pellets qauv hauv kev ua lag luam. Ntoo pellet standardization yog ib qho kev tsim ua ke tshwj xeeb kev cai tshwj xeeb ntawm cov khoom hauv kev lag luam. Txij li cov txheej txheem Austrian (ÖNORM M1735) tau luam tawm xyoo 1990, ntau tus tswvcuab EU tau tsim lawv tus kheej cov qauv pellets hauv tebchaws, xws li DINplus (Lub Tebchaws Yelemees), NF (Fabkis), Pellet Gold (Ltalis), thiab lwm yam. Raws li kev ua lag luam pellet ntau tshaj plaws hauv ntiaj teb, European Commission tau tsim tsa cov qauv EU (CEN TC335- EN 14961) rau cov khoom siv roj, uas yog raws li Austrian cov qauv (ÖNORM M1735).
Raws li txhua tus qauv ntawm cov ntoo pellets uas twb muaj lawm, peb muab koj cov lus qhia tshwj xeeb kom pab koj txheeb xyuas cov ntoo pellets zoo.
Peb tau nthuav qhia txhua qhov tseem ceeb rau koj kom ceev nrawm saib seb tus ntoo pellet zoo npaum li cas. Cia li ua raws cov theem hauv qab no:
COV NTAUB NTAWV PW PWET KHOOM TXUJ YEEM: ≤ 1MM
Feem ntau ntoo pellet diameters yog 6mm thiab 8mm. Feem ntau, qhov loj dua txoj kab uas hla yog, qhov kev ua tau zoo pelletizing nws muaj. Tab sis yog hais tias lub taub txoj hauv qab 5 hli, lub zog siv ntau zog thiab lub peev xwm tsis kam. Tsis tas li, vim muaj cov ntawv pellets, qhov ntim ntawm cov khoom yog compressed, nws txuag tau qhov chaw cia. Ntxiv mus, nws yooj yim rau kev thauj, yog li tus nqi thauj tsawg. Ntawm tag nrho cov qauv uas twb muaj lawm, muaj kev nkag siab txog cov dav uas tsis yog, uas tsis pub tshaj 1mm.
COV NTSIAB LUS PELLETS TXHEEJ TXHEEM: ≤ 10%
Raws li txhua tus txheej txheem ntoo pellets, cov ntsiab lus xav tau ntawm noo noo zoo ib yam, tsis pub ntau tshaj 10%. Technically, thaum lub sijhawm ua, txheej txheem dej yog qhov binder thiab roj nplua nyeem. Yog tias cov dej noo noo tsawg dhau, cov pellets tsis tuaj yeem txuas ntxiv, yog li cov ntawv ntim yuav deformation, thiab qhov ntom ntog qis dua li ntawm cov kab pellets uas ib txwm muaj. Tab sis yog tias cov dej noo ntsiab lus ntau dhau, qhov kev siv lub zog yuav nce, thiab lub ntim yuav tseem yuav nce, ib txwm, cov pellets yuav muaj qhov chaw ntxhib, thiab yog mob hnyav, cov khoom nyoos tuaj yeem tawg los ntawm kev tuag ntawm lub pellet zeb. Txhua tus txheej txheem pellet qhia tias cov dej noo zoo tshaj plaws rau ntoo pellets yog 8%, thiab kev ya raws zoo tshaj plaws rau lis biomass pellets yog 12%. Lub pellet noo noo tuaj yeem ntsuas tau los ntawm kev ntsuas cua av ntsuas dej.
PELLET BULK DENSITY: ≥ 600 KG / M3
Qhov ntom ntawm cov ntoo pellets yog ib qho tseem ceeb tshaj plaws, qhov ib txwm muaj peev xwm raug muab faib ua feem ntau thiab ntom ntoo pellets. Lub cev ntom ntom ntom ntaws yog cov khoom ntiag tug ntawm cov ntaub ntawv hmoov, xws li cov hmoov pellets, cov tshuaj formula yog qhov ntau ntawm cov hmoov ntim cov khoom faib los ntawm qhov ntim lawv xav tau. Kev cuam tshuam rau qhov hnyav tsis yog tsuas yog kev sib txuas ua ke xwb tab sis kuj muaj kev thauj mus los thiab cov nqi thauj khoom.
Ntxiv mus, cov hmoov pellets kuj tseem yog ib qho cuam tshuam rau nws qhov thooj loj thiab cov kev sib txuas, qhov ntau dua qhov nws muaj, lub sijhawm ntev dua nws yuav nyob ntev.
PELLET NEEG KHO TSHUAB CUA: 96.5%
Lub tshuab thev naus laus zis tseem yog qhov ntsuas tseem ceeb. Thaum lub sijhawm kev thauj mus los thiab kev cia khoom, cov pellets nrog lub tshuab hluav taws xob qis dua tau yooj yim, nws yuav ua rau cov hmoov ntawd nce ntxiv. Ntawm txhua yam ntawm biomass pellets, cov ntoo pellets kom muaj kev saib xyuas lub tshuab siab tshaj plaws, txog 97.8%. Piv rau tag nrho cov qauv biomass pellets, cov khoom siv thev naus laus zis no yeej tsis tsawg dua 95%.
QW KEV TSHUAJ TIV THAIV KEV TXHAWB TSHAJ
Rau txhua tus neeg siv kawg, qhov teeb meem muaj kev txhawj xeeb tshaj plaws yog cov pa tawm, uas yog muaj Nox, Sox, HCl, PCCD (polychlorinated dibenzo-p-dioxins) thiab ya tshauv. Cov ntsiab lus Nitrogen thiab Sulphur hauv cov pellets tau txiav txim siab Nox thiab Sox. Tsis tas li ntawd, qhov teeb meem corrosion yog txiav txim siab los ntawm cov ntsiab lus chlorine. Txhawm rau kom muaj kev sib tw ua kom tau zoo dua, tag nrho cov txheej txheem pellets pom zoo kom muaj cov ntsiab lus tshuaj lom neeg qis.
Cov ntoo pellet zoo rau cov ntoo pellet zoo rau cov khoom siv zoo: Txais tos kuaj GreenVinci biomass gasification burner rau ntoo pellet, briquettes, ntoo chips, cav ntoo pov tseg thiab lwm yam rau cov phiaj xwm cua kub.
