mīkini paʻi lāʻau

Pūnaehana ʻoki

Komo ka ʻōpala i loko o ka hale kūʻai ma o ka conveyor, ʻoki ʻia e ka mea paʻi, a laila komo i loko o ka hale waihona lāʻau. Hoʻopaʻa ʻia ia ma o ka pale haʻalulu e pale i nā ʻāpana lāʻau like ʻole, a laila komo i ka ʻāpana holoi wai.

(He nui nā mea kūʻai e hoʻohana ana i nā ʻōpala lāʻau ma ke ʻano he kumu.

Ka wehe ʻana i nā haumia

Hoʻomaʻemaʻe ka ʻōnaehana hoʻomaʻemaʻe i nā ʻāpana lāʻau i ʻoki ʻia i nā kikoʻī e wehe i ka lepo, ke one a me nā mea haumia ʻē aʻe i loko o nā ʻāpana lāʻau e hōʻoia i ka maʻemaʻe o ka biomass pellet i hoʻoheheʻe ʻia a hoʻonui i ka waiwai calorific o ka wahie.

ʻŌnaehana hoʻomaloʻo

ʻO ka hoʻomaloʻo ʻana i ka umu wela i hoʻohana ʻia i ke kaʻina hana kuʻuna he paʻakikī ke kāohi i ka makū a he hewa nui. Hoʻohana ʻia ke kinoea flue wela kiʻekiʻe ma ke ʻano he wela wela, a aia ka hewa o ka hoʻomalu ʻana i ka wai i loko o 0.01. Ma muli o ke kaohi pono ʻana o ka wai fiber, ua hōʻoia ʻia ka maikaʻi a me ka hoʻopuka ʻana o ka wahie hoʻoheheʻe lāʻau.

(Inā ma lalo o 15% ka makū o kāu mau mea maka, ʻaʻohe pono e hoʻomaloʻo)

Pūnaehana kuʻi

Hoʻopili piha ʻia nā mea maka lāʻau ma o ka ʻōnaehana wili lāʻau e hoʻomaʻamaʻa i ka hana hou o ka granulation.

ʻO ka Pelleting & Hoʻoluʻu & Hoʻomaʻamaʻa & ʻeke

Loaʻa i ka lāʻau ka nui o ka cellulose, hemicellulose a me ka lignin, ʻoi aku ma mua o 2/3 o nā mea kanu. Ke piʻi ka mahana i 70 a 110 ° C, palupalu ka lignin a piʻi ka ikaika adhesive; ma 200 a 300 ° C, hoʻoikaika ka degere palupalu.

I kēia manawa, hoʻokumu ʻia nā pellets lāʻau me kekahi ʻano ma o ka hoʻopili ʻana i ke kaomi o waho a me ka hoʻopaʻa ʻana. No ka mea ua hoʻopili ʻia nā molekole fiber inelastic a i ʻole viscoelastic me kekahi i kekahi, ʻaʻole lākou e hoʻi i ko lākou ʻano kumu ma hope o ka wehe ʻana i ke kaomi o waho.

Ma hope o ka hoʻoluʻu ʻana, ka nānā ʻana, ka nānā ʻana i ka maikaʻi, ka hoʻopili ʻana a me nā kaʻina hana ʻē aʻe, hoʻopili ʻia ka wahie pellet lāʻau a hoʻokumu ʻia.

• Ke piʻi nei ke kumukūʻai o nā wahie mōʻalihaku e like me ka lanahu, ka aila a me ke kinoea maoli. ʻO ka piʻi ʻana o ke kumukūʻai wahie fossil e hoʻonui i ke kumukūʻai o ka hana ʻana ma kēlā me kēia mea kanu.
• Ke ulu nui nei nā pilikia haumia o ke kaiapuni. I ka wā o ka puhi ʻana o ka lanahu, nui nā mea haumia like ʻole, e like me ka sulfur dioxide, nitrogen dioxide, carbon monoxide, carbon particles, dust, etc.
• Hiki ke loaʻa nā mea maka o nā pellet biomass ma nā wahi a pau, a he haʻahaʻa ke kumukūʻai o nā kumu lāʻau. ʻO nā ʻāpana lāʻau, nā ʻōpala, nā ʻōpala, nā lālā, nā ʻōpala pulupulu, nā ʻōpala raiki, nā mauʻu, a me nā mea ʻē aʻe, he mau mea maka no ka hana ʻana i nā pellet. ʻO kēia mau mea maka a pau he ʻōpala mai nā hale wili lāʻau a me nā mahiʻai, a hiki iā ʻoe ke kiʻi maʻalahi i nā kumukūʻai haʻahaʻa.

• He ʻuʻuku ke kumu o ka lāʻau, a ʻoi aku ka laulā o ka hoʻohana ʻana i ka lāʻau lāʻau. Hiki ke hoʻohanaʻia e hana i nā mea hana kiʻekiʻe, nā mea hana lima, nā mea kani, ka pepa, a me nā mea'ē aʻe. A hoʻohana maikaʻi nā pellets i nā ʻōpala a me nā ʻōpala mai kēia mau noi.
• Ma nā kua'āina a i ʻole nā ​​ʻāpana ʻāina o nā ʻāina e ulu ana, hiki i nā poʻe he nui ke hoʻohana i nā mea lāʻau ʻē aʻe e like me ka wahie home, e like me nā ʻōpala pulupulu. Akā ʻokoʻa ka nui o nā kumu lāʻau, nā ʻano a me nā mea maʻemaʻe, kahi e paʻa ʻole ai ka hana puhi ahi, a ʻaʻole hiki i kekahi mau mea maka nui ke komo pololei i ka umu.
  ʻO nā pellets kahi ʻano wahie me ka leo like ʻole, kiʻekiʻe kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa a me ka maʻalahi o ka puhi ʻana. Hiki ke hoʻohana ʻia nā pellets i nā ʻōnaehana hoʻopau like ʻole. Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana puhi pellet, ua puka mai ʻelua ʻano ʻano o nā ʻōnaehana puhi pellet, ʻoihana a me nā hale noho.
• ʻIke mākou a pau inā makemake mākou e hoʻomālamalama i nā lāʻau a i ʻole nā ​​lālā, ʻaʻole ia he hana maʻalahi. ʻOi aku ka maʻalahi o nā pellets. Eia kekahi, ʻoi aku ka maikaʻi o ka puhi ʻana i nā pellets, ʻoi aku ka liʻiliʻi o ka uahi, a ʻoi aku ka nui o ka calorific waiwai ma mua o nā mea lāʻau.

ʻĀpana lāʻau

ʻO nā ʻāpana lāʻau he mau ʻāpana lāʻau liʻiliʻi o 5-50mm, a ʻoi aku ka maikaʻi o ka puhi ʻana ma mua o nā lālā nui a me nā ʻāpana lāʻau. Inā ʻoi aku ka nui o kēia mau mea maka, e pani lākou i ka ʻōnaehana hānai o ka paila; inā he liʻiliʻi loa lākou, e hoʻoulu ʻia lākou i ka puhi ʻole i ka paila biomass. ʻO nā ʻāpana lāʻau me ka ʻili ʻili me ka liʻiliʻi o ke ahi a hoʻonui i ka lehu. No laila, pono e mālama mua ʻia kēia mau ʻāpana lāʻau ma mua o ke puhi ʻia ʻana i loko o nā paila biomass.

ʻO ke kaʻina hana maʻamau o ka wahie puʻupuʻu lāʻau, ʻo ia nā kumulāʻau a me nā ʻōpala i ʻoki ʻia a maloʻo e hōʻoia i ka hiki ʻana o ka wai i ka pae i makemake ʻia.

Nā ʻāpana lāʻau

Hana ʻia nā pellet lāʻau biomass me nā ʻāpana lāʻau ma kahi o 5mm i hoʻokuʻu ʻia ma o ka mīkini pellet biomass. Hoʻohana ʻia nā lālā lāʻau a me nā lālā lāʻau ʻē aʻe i nā pellet cylindrical o 6-10mm a me 10-30mm ka lōʻihi.

Hana ʻia nā pellet lāʻau me nā ʻāpana lāʻau maʻemaʻe a ʻaʻole i loaʻa i nā kemika hana ʻē aʻe. ʻO nā pellets i hana ʻia he kiʻekiʻe ka wahie kiʻekiʻe, haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi o ka puhi ʻana ma mua o ka hoʻopau pololei ʻana i nā ʻāpana lāʻau. Hoʻoponopono pū ia i ka pilikia o nā ʻāpana lāʻau, sawdust a me nā lāʻau ʻē aʻe i hiki ʻole ke lawe. ninau.

Hana ʻia nā pellets lāʻau ma ka ʻoki ʻana, ka ʻoki ʻana, ka hoʻomaloʻo a me ka pelletizing lāʻau, ka ʻōpala hana, nā lālā a me nā biomass ʻē aʻe.

Nā kumu ʻē aʻe:

• Pono e noʻonoʻo e hiki i kekahi mau paila biomass ke hoʻohana i nā pellet lāʻau a me ka wahie ʻāpana lāʻau, e ʻoi aku ka maʻalahi o ka lako. Eia nō naʻe, ʻaʻole kūpono kekahi mau paila lāʻau a me kā lākou mau mea hānai haiki no ka hoʻololi ʻana i nā ʻāpana lāʻau.
• Pono e hoʻomanaʻo ʻia inā makemake ʻia ka hoʻololi ʻana i ke ʻano wahie, pono e hoʻihoʻi ʻia ka paila a hoʻololi ʻia nā hoʻonohonoho.
• He mea koʻikoʻi nō hoʻi ka mālama ʻana i ka wahie a me ka lawe ʻana i ka wahie i ka wā e hoʻoholo ai i ka wahie e hoʻohana ai. Inā liʻiliʻi ka wahi e waiho ai, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā pellet lāʻau.
• ʻO ka pinepine o ka hoʻouna ʻana he kumu nui i ka hoʻolālā ʻana i kahi ʻōnaehana. ʻO ka nui o ka mana i hāʻawi ʻia, ʻoi aku ka liʻiliʻi o ka wahie, akā ʻoi aku ka nui o ka nui o nā ʻāpana. Hoʻohana ʻia ka wahie nui i nā paila nui no ka hana ʻana, no laila pono e noʻonoʻo ʻia ka nui o ka lumi a me ka manawa lawe.
• No ka mea, ʻaʻole like ka wai o nā pahu lāʻau e like me nā pellets lāʻau, paʻakikī ka lawe ʻana, a pono e hoʻouka ʻia nā mea kōkua e like me nā kaʻa a i ʻole nā ​​pahu pahu ma ka hāpai ʻana. Hoʻouna pinepine ʻia nā pellets i ka nui, ma o nā trailers a i ʻole pipelines. ʻO kēia kekahi kumu i ke koho ʻana i kahi ʻōnaehana wahie pellet.
