Kugwiritsira ntchito biomass yotayirira kupanga mafuta a pellet kutentha kwa chipinda ndi njira yosavuta komanso yolunjika yogwiritsira ntchito mphamvu za biomass. Tiyeni tikambirane mawotchi kupanga luso la mbewu udzu pellets ndi inu.

Pambuyo pa zinthu za biomass zomwe zili ndi mawonekedwe otayirira komanso otsika kwambiri zimayendetsedwa ndi mphamvu zakunja, zopangirazo zimadutsa magawo a kukonzanso, kusinthika kwamakina, kusinthika kwa zotanuka ndi kusinthika kwa pulasitiki. Ma cellulose a inelastic kapena viscoelastic cellulose amalumikizana ndi kupotozedwa, Kuchuluka kwa zinthuzo kumachepetsedwa ndipo kachulukidwe kake kakuwonjezeka.

Chiŵerengero cha kuponderezedwa kwa mphete kufa kwa zida zamakina a biomass pellet kumatsimikizira kukula kwa kukakamiza kowumba. The mapadi zili zopangira monga chimanga mapesi ndi bango ndi yaing'ono, ndipo n'zosavuta deform pamene extruded ndi mphamvu kunja, kotero psinjika chiŵerengero cha mphete kufa chofunika akamaumba ndi yaing'ono. , ndiko kuti, kuthamanga kwa kuumba kumakhala kochepa. The mapadi zili utuchi ndi mkulu, ndi psinjika chiŵerengero cha mphete kufa chofunika akamaumba ndi lalikulu, ndiye akamaumba kuthamanga ndi lalikulu. Chifukwa chake, zopangira zosiyanasiyana za biomass zimagwiritsidwa ntchito popanga mafuta opangidwa ndi pellet, ndipo kuponderezana kwa mphete kumayenera kugwiritsidwa ntchito. Pazinthu za biomass zomwe zili ndi cellulose yofananira muzopangira, mphete imafa yokhala ndi chiŵerengero chofanana cha psinjika ingagwiritsidwe ntchito. Pakuti tatchulazi zopangira, monga psinjika chiŵerengero cha mphete kufa ukuwonjezeka, ndi tinthu kachulukidwe ukuwonjezeka, mowa mphamvu ukuwonjezeka, ndi linanena bungwe ukuwonjezeka. Pamene psinjika chiŵerengero china kufika, kachulukidwe a anapanga particles ukuwonjezeka pang'ono, mowa mphamvu ukuwonjezeka moyenerera, koma linanena bungwe amachepetsa. Kufa kwa mphete yokhala ndi compression ratio ya 4.5 imagwiritsidwa ntchito. Ndi utuchi monga zopangira ndi mphete kufa ndi psinjika chiŵerengero cha 5.0, kachulukidwe wa pellet mafuta akhoza kukwaniritsa zofunika khalidwe, ndi mowa mphamvu ya dongosolo zida ndi otsika.

Yemweyo yaiwisi aumbike mu mphete kufa ndi osiyana psinjika chiŵerengero, kachulukidwe wa pellet mafuta ukuwonjezeka pang`onopang`ono ndi kuwonjezeka psinjika chiŵerengero, ndipo mkati osiyanasiyana psinjika chiŵerengero, kachulukidwe amakhalabe ndi khola, pamene psinjika chiŵerengero ukuwonjezeka kumlingo wakuti, The zopangira sadzatha kupangidwa chifukwa cha kuthamanga kwambiri. Kukula kwa mankhusu a mpunga ndi kwakukulu ndipo phulusa ndi lalikulu, choncho zimakhala zovuta kuti mankhusu a mpunga apange tinthu tating'onoting'ono. Pazinthu zomwezo, kuti mupeze kachulukidwe kakang'ono ka tinthu, ziyenera kupangidwa pogwiritsa ntchito chiŵerengero chachikulu cha mphete.
Mphamvu ya zopangira tinthu kukula pa akamaumba zinthu

The tinthu kukula kwa zotsalira zazomera zopangira ali ndi chikoka pa akamaumba zinthu. Ndi kuwonjezeka kwa tinthu kukula kwa chimanga phesi ndi bango zopangira, kachulukidwe wa akamaumba particles pang'onopang'ono amachepetsa. Ngati tinthu kukula kwa zopangira ndi laling'ono kwambiri, zidzakhudzanso kachulukidwe tinthu. Chifukwa chake, mukamagwiritsa ntchito biomass monga mapesi a chimanga ndi mabango ngati zida zopangira tinthu tating'onoting'ono, ndikofunikira kusunga kukula kwa tinthu pa 1-5 nun.

Mphamvu ya chinyezi mu feedstock pa kachulukidwe wa pellet mafuta

Pali kuchuluka koyenera kwa madzi omangika ndi madzi aulere m'thupi lachilengedwe, lomwe lili ndi ntchito yamafuta, yomwe imachepetsa kukangana kwamkati pakati pa tinthu tating'onoting'ono ndikuwonjezera madzimadzi, potero kulimbikitsa kutsetsereka ndi kuyenerera kwa tinthu tating'onoting'ono tambirimbiri. Pamene madzi opangidwa ndi biomass zopangira zopangira madzi Pamene chinyezi chimakhala chochepa kwambiri, tinthu tating'onoting'ono sitingathe kufalikira, ndipo tinthu tating'ono tating'ono tating'ono ting'onoting'ono sitingagwirizane mwamphamvu, choncho sitingapangidwe. Pamene chinyezi chimakhala chokwera kwambiri, ngakhale kuti tinthu tating'onoting'ono titha kufalikira mokwanira ku njira yopita patsogolo kwambiri, ndipo tinthu tating'onoting'ono tomwe timatha timana tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono, koma Popeza kuti madzi ochulukirapo amadzimadzi amatulutsidwa ndikugawidwa pakati pa tinthu tating'onoting'ono, zigawo za tinthu sizingagwirizane kwambiri, kotero sizingapangidwe.

Choncho, pamene makina a biomass pellet ndi zipangizo zimagwiritsa ntchito biomass monga mapesi a chimanga ndi mabango ngati zipangizo zopangira mafuta a pellet, chinyezi chazopangira chiyenera kusungidwa pa 12% -18%.

Pansi yachibadwa kutentha zinthu, pa psinjika akamaumba ndondomeko zotsalira zazomera zopangira zopangira, ndi particles ndi olumala ndi pamodzi mu mawonekedwe a mutual meshing, ndi tinthu zigawo pamodzi mu mawonekedwe a mgwirizano kugwirizana. Zomwe zili mu cellulose muzopangira zimatsimikizira zovuta za kuumba Kukwera kwa cellulose, kumakhala kosavuta kuumba. The tinthu kukula ndi chinyezi wa zipangizo ndi kwambiri zimakhudza akamaumba zinthu.
