AKHISHWA KANJANI AMAPHELETHI?

Uma kuqhathaniswa nobunye ubuchwepheshe bokuthuthukisa i-biomass, i-pelletisation iyinqubo esebenza kahle, elula futhi enezindleko eziphansi.Izinyathelo ezine ezibalulekile kule nqubo yilezi:

• ukugaya kuqala kwempahla eluhlaza
• ukomiswa kwempahla eluhlaza
•ukugaya impahla eluhlaza
• ukuminyana komkhiqizo

Lezi zinyathelo zivumela ukukhiqizwa kukaphethiloli olinganayo onomswakama ophansi kanye nokuminyana kwamandla aphezulu.Uma kwenzeka izinto ezomile zitholakala, ukugaya kuphela kanye nokuminyana kuyadingeka.

Njengamanje cishe amaphesenti angama-80 ama-pellets akhiqizwa emhlabeni wonke enziwe nge-woody biomass.Ezimweni eziningi, kusetshenziswa imikhiqizo evela ezigayweni ezisaha ezifana nesaha kanye nokushefa.Ezinye izigayo ezinkulu ze-pellet nazo zisebenzisa izinkuni zenani eliphansi njengempahla eluhlaza.Inani elikhulayo lama-pellets adayiswayo enziwa ngezinto ezifana nenqwaba yezithelo ezingenalutho (kusuka ku-oil palm), i-bagasse, namakhoba elayisi.

Ubuchwepheshe bokukhiqiza ngezinga elikhulu

Isitshalo se-pellet esikhulu kunazo zonke emhlabeni mayelana nokuphuma kwe-pellet yi-Georgia Biomass Plant (USA) eyakhiwe ngu-Andritz.Lesi sitshalo sisebenzisa izingodo ezikhula ngokushesha ezikhiqizwa emasimini kaphayini.Izingodo ziyasuswa, zichotshozwe, zomiswe futhi zigaywe ngaphambi kokuminyana ezigayweni ze-pellet.Umthamo we-Georgia Biomass Plant ungamathani angu- 750 000 amapellets ngonyaka.Isidingo sokhuni salesi sitshalo sifana nesomshini wokugaya amaphepha.

Ubuchwepheshe bokukhiqiza obuncane

Ubuchwepheshe bezinga elincane lokukhiqiza ama-pellet ngokuvamile busekelwe ku-sawdust shavings kanye nokusikeka okuvela kumasaha noma izimboni zokucubungula ukhuni (Abakhiqizi bephansi, izicabha kanye nefenisha njll.) okwengeza inani emikhiqizweni yabo ngokushintsha ama-pellets.Impahla ewuketshezi eyomile iyagaywa, futhi uma kudingekile, ilungiselwe inani elifanele lomswakamo kanye nezinga lokushisa elilungile ngokuyilungisa kusengaphambili ngesitimu ngaphambi kokungena emshinini we-pellet lapho iminyene khona.Into epholile ngemva kokugaya inciphisa izinga lokushisa lama-pellets ashisayo emva kwalokho ama-pellets ahlungwa ngaphambi kokuba afakwe esikhwameni, noma adluliselwe ekugcineni komkhiqizo ophelile.
