Biomass wahie pellet machine loaʻa nā koi maʻamau no nā mea maka i ke kaʻina hana. ʻO ka maikaʻi loa o nā mea maka e hopena i ka haʻahaʻa haʻahaʻa biomass a ʻoi aku ka pauka, a ʻo nā mea makaʻala ʻoi aku ka nui o nā mea wili, no laila e hoʻopilikia ʻia ka nui o nā mea maka. Hoʻopili ka maikaʻi o nā ʻāpana i hoʻokumu ʻia i ka pono hana a me ka hoʻohana mana.

ʻO ka mea maʻamau, ʻoi aku ka paʻakikī o ka hoʻopili ʻana i nā mea maka me ka liʻiliʻi liʻiliʻi. Eia kekahi, pili pono ka impermeability, hygroscopicity a me ka hoʻoheheʻe ʻana o nā mea maka i ka nui o ka particle.

Ke loaʻa nā ʻāpana like ʻole o ka mea like i ka haʻahaʻa haʻahaʻa, ʻoi aku ka nui o ka nui o ka nui o ka mea, ʻoi aku ka lohi o ka hoʻololi ʻana i ka density, akā me ka piʻi ʻana o ka puʻe, e liʻiliʻi kēia ʻokoʻa ke hiki i ke kaomi i kekahi waiwai.

ʻO nā ʻāpana me ka liʻiliʻi liʻiliʻi he ʻāpana ili kikoʻī nui, a hiki i nā ʻāpana lāʻau ke komo i ka makū a loaʻa hou ka maʻa. ʻO ka mea ʻē aʻe, i ka liʻiliʻi ʻana o ka nui o ka ʻāpana, ua maʻalahi ka hoʻopiha ʻana i nā void inter-particle, a ʻoi aku ka nui o ka compressibility, e hana ai i ke koena o nā ʻāpana biomass kūloko. E liʻiliʻi ke koʻikoʻi, a laila e hoʻonāwaliwali i ka hydrophilicity o ka poloka i hoʻoheheʻe ʻia a hoʻomaikaʻi i ka wai permeability.

He aha nā kūlana maka no ka hana ʻana onā mīkini pellet wahie biomass?

ʻOiaʻiʻo, pono e loaʻa kahi palena liʻiliʻi pū kekahi. Inā liʻiliʻi ka nui o nā ʻāpana lāʻau, e emi ana ka hiki ke hoʻohālikelike ʻia ma waena o nā ʻāpana lāʻau, e hopena i ka hoʻoheheʻe maikaʻi ʻana a i ʻole ka emi ʻana o ke kūʻē ʻana i ka haki ʻana. No laila, ʻoi aku ka maikaʻi o ka liʻiliʻi ma mua o 1mm.

Inā ʻoi aku ka nui o ka sawdust ma mua o 5MM, e hoʻonui ʻia ka friction ma waena o ka roller pressing a me ka mea hana abrasive, e hoʻonui ʻia ka friction o ka mīkini pellet biomass fuel, a e hoʻopau ʻia ka hoʻohana ʻana i ka ikehu pono ʻole.

No laila, ʻo ka hana ʻana o nā pellets wahie biomass e koi maʻamau i ka nui o ka nui o nā mea maka e mālama ʻia ma waena o 1-5 mm.
