KODI MA PELLETTS AMAPANGA BWANJI?

Poyerekeza ndi matekinoloje ena opititsa patsogolo biomass, pelletisation ndi njira yabwino, yosavuta komanso yotsika mtengo. Njira zinayi zazikuluzikulu zomwe zili mkati mwa njirayi ndi:

• Pre-mphero wa zopangira
• Kuyanika kwa zopangira
• mphero zopangira
• kachulukidwe wa mankhwala

Masitepewa amathandizira kupanga mafuta osakanikirana ndi chinyezi chochepa komanso kachulukidwe kamphamvu. Ngati zouma zouma zilipo, mphero ndi kachulukidwe ndizofunika.

Pakadali pano pafupifupi 80 % ya ma pellets opangidwa padziko lonse lapansi amapangidwa kuchokera ku biomass yamatabwa. Nthawi zambiri, zinthu zopangidwa kuchokera ku mphero zocheka monga macheka ndi zometa zimagwiritsidwa ntchito. Mphero zina zazikulu za pellet zimagwiritsanso ntchito nkhuni zamtengo wotsika ngati zopangira. Kuchulukirachulukira kwa ma pellets ogulitsidwa akupangidwa kuchokera ku zinthu monga mulu wa zipatso zopanda kanthu (kuchokera ku mafuta a kanjedza), bagasse, ndi mankhusu a mpunga.

Tekinoloje yayikulu yopanga

Chomera chachikulu kwambiri padziko lonse lapansi pakupanga ma pellet ndi Georgia Biomass Plant (USA) yopangidwa ndi Andritz. Chomerachi chimagwiritsa ntchito mitengo yamitengo yomwe ikukula mwachangu yomwe imapangidwa m'minda ya paini. Zipikazo zimachotsedwa, kudulidwa, zowumitsidwa ndi kugayidwa zisanapangike mu mphero za pellets. Mphamvu ya Georgia Biomass Plant ndi pafupifupi matani 750 000 a pellets pachaka. Mtengo wa matabwa wa chomerachi ndi wofanana ndi wa mphero ya pepala.

Tekinoloje yopangira zazing'ono

Tekinoloje yaying'ono yopangira ma pellet nthawi zambiri imatengera utuchi wometa ndikudula kuchokera ku macheka kapena mafakitale opangira matabwa (Opanga pansi, zitseko ndi mipando ndi zina) zomwe zimawonjezera phindu pazogulitsa zawo posintha kukhala ma pellets. Zouma zouma zimagayidwa, ndipo ngati zingafunike, zimasinthidwa kuti zikhale ndi chinyezi chokwanira komanso kutentha kwabwino kwambiri poyimitsa ndi nthunzi isanalowe mu mphero ya pellet pomwe imakhazikika. Kuziziritsa pambuyo pa mphero kumachepetsa kutentha kwa ma pellets otentha pambuyo pake ma pellets amasefa asananyamulidwe, kapena kutumizidwa ku malo omaliza.
