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 kutsika kwapang'onopang'ono 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 kamawonjezeka.

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 mabango ndi yaing'ono, ndipo n'zosavuta opunduka 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, zida 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, ndipo 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.

Zomwezo zopangira zimapangidwa mu mphete kufa ndi mitundu yosiyanasiyana ya kupsinjika, kachulukidwe ka mafuta a pellet kumawonjezeka pang'onopang'ono ndi kuwonjezeka kwa chiŵerengero cha kuponderezana, ndipo mkati mwamtundu wina wa kupsinjika kwa chiŵerengero, kachulukidwe kamakhala kokhazikika, pamene chiŵerengero cha psinjika chikuwonjezeka mpaka pang'ono, The zopangira sadzatha kupangidwa chifukwa cha kuthamanga kwambiri.Ukulu wa tirigu wa mankhusu a mpunga ndi waukulu ndipo phulusa ndi lalikulu, choncho zimakhala zovuta kuti mankhusu a mpunga apange tinthu ting’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 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 limagwira ntchito yamafuta, omwe amachepetsa kukangana kwamkati pakati pa tinthu tating'onoting'ono ndikuwonjezera madziwo, 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'onoting'ono tating'ono tating'ono ting'onoting'ono sitingagwirizane mwamphamvu, kotero kuti sangathe kupangidwa.Pamene chinyezi okhutira kwambiri, ngakhale particles akhoza mokwanira anawonjezera mu malangizo perpendicular kwa pazipita chachikulu nkhawa, ndi particles akhoza mauna wina ndi mzake, koma Popeza madzi ambiri mu zopangira ndi extruded ndi kugawira pakati pa tinthu zigawo. , zigawo za tinthu sizingagwirizane kwambiri, choncho 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.
