YUAV UA LI CAS PELLETS?

Piv nrog rau lwm cov thev naus laus zis ntawm kev nce qib biomass, pelletisation yog ib qho kev ua tau zoo, yooj yim thiab tus nqi qis.Plaub kauj ruam tseem ceeb hauv cov txheej txheem no yog:

• pre-milling ntawm raw khoom
• ziab ntawm raw khoom
• milling ntawm raw khoom
• densification ntawm cov khoom

Cov kauj ruam no pab tsim cov roj homogeneous nrog cov av qis thiab lub zog siab ceev.Nyob rau hauv cov ntaub ntawv qhuav qhuav muaj, tsuas yog milling thiab densification yog tsim nyog.

Tam sim no kwv yees li 80% ntawm lub ntiaj teb ua pellets yog tsim los ntawm woody bio-mass.Feem ntau, cov khoom siv los ntawm cov saw mills xws li saw- plua plav thiab shavings yog siv.Qee lub tshuab pellet loj kuj siv cov ntoo uas tsis muaj nqi ua cov khoom siv raw.Kev nce ntim ntawm cov khoom lag luam pellets yog tsim los ntawm cov ntaub ntawv xws li cov txiv hmab txiv ntoo khoob (los ntawm cov roj xibtes), bagasse, thiab mov husk.

Loj scale ntau lawm technology

Lub ntiaj teb loj tshaj plaws pellet cog nyob rau hauv cov nqe lus ntawm pellet tso zis yog lub Georgia Biomass Plant (USA) tsim los ntawm Andritz.Cov nroj tsuag no siv cov ntoo loj hlob sai heev uas tsim hauv cov ntoo thuv.Cov cav yog debarked, chipped, qhuav thiab milled ua ntej densification nyob rau hauv pellet mills.Georgia Biomass Plant muaj peev xwm yog li ntawm 750 000 tonnes ntawm pellets ib xyoos.Cov ntoo xav tau ntawm cov nroj tsuag no zoo ib yam li qhov nruab nrab ntawm daim ntawv zeb.

Kev siv tshuab me me

Cov tshuab me me rau kev tsim cov pellet feem ntau yog ua raws li cov sawdust shavings thiab txiav tawm los ntawm sawmills lossis ntoo ua lag luam (Cov neeg tsim khoom ntawm cov plag tsev, qhov rooj thiab rooj tog thiab lwm yam) uas ntxiv cov nqi rau lawv cov khoom los ntawm kev hloov mus rau hauv pellets.Cov khoom siv qhuav qhuav yog milled, thiab yog tias xav tau, kho kom haum rau qhov zoo ntawm cov av noo thiab qhov zoo tshaj plaws kub los ntawm pre-conditioning nrog chav ua ntej nkag mus rau pellet zeb qhov twg nws yog densified.Lub tshuab txias tom qab lub tshuab pellet txo qhov kub ntawm cov pellets kub tom qab uas cov pellets tau sifted ua ntej yuav ntim, los yog xa mus rau cov khoom tiav lawm.
