Kungakhathaliseki ukuthi uhlela ini: ukuthenga amapulangwe ezinkuni noma ukwakha isitshalo se-pellet yezinkuni, kubalulekile kuwe ukwazi ukuthi yiziphi izinkuni zezinkuni ezinhle futhi ezimbi. Ngenxa yokuthuthukiswa komkhakha, kunamazinga angaphezu kwe-1 e-wood pellets emakethe. I-Wood pellet standardization iyincazelo ehlanganisiwe ehlanganisiwe yemikhiqizo embonini. Njengoba amazinga ase-Austrian (ÖNORM M1735) ashicilelwe ngo-1990, amalungu amaningana e-EU asungule izindinganiso zawo kazwelonke zamapellets, njenge-DINplus (Germany), NF (France), Pellet Gold (Italy), njll. Njengemakethe ye-pellet enkulu kunazo zonke. emhlabeni, Ikhomishini YaseYurophu isungule amazinga e-EU (CEN TC335- EN 14961) kaphethiloli oqinile, osuselwe kumazinga ase-Austrian (ÖNORM M1735).

Ngokusekelwe kuwo wonke amazinga akhona amapulangwe okhuni, sikunikeza imininingwane ethuthukisiwe ukukusiza ukuhlonza amapulangwe okhuni asezingeni eliphezulu.

Sifingqa zonke izici ezibalulekile ukuze uhlole ngokushesha ukuthi i-pellet yokhuni inhle kangakanani. Vele ulandele izinyathelo ezilandelayo:

Imithamo yepellet yokhuni ejwayeleke kakhulu yi-6mm kanye ne-8mm. Ngokuvamile, ubukhulu be-diameter buncane, ukusebenza okungcono kwe-pelletizing enakho. Kodwa uma ububanzi bungaphansi kuka-5mm, ukusetshenziswa kwamandla kuyenyuka futhi umthamo wehliswa. Futhi, ngenxa yokuma kwama-pellets, umthamo womkhiqizo ucindezelwe, ulondoloze indawo yokugcina. Ngaphezu kwalokho, kulula ukuthutha, ngakho izindleko zokuhamba ziphansi. Phakathi kwazo zonke izindinganiso ezikhona, kukhona ukuqonda okuvamile mayelana namaphutha obubanzi, okungekho ngaphezu kwe-1mm.

Ngokwazo zonke izindinganiso ze-pellets zokhuni, umswakama odingekayo ufana, akukho ngaphezu kwe-10%. Ngobuchwepheshe, phakathi nenqubo, okuqukethwe kwamanzi yi-binder kanye ne-lubricant. Uma umswakama uphansi kakhulu, ama-pellets awakwazi ukunwetshwa ngokugcwele, ngakho-ke ama-pellets angase abe yi-deformation, futhi ukuminyana kuphansi kune-pellets evamile. Kodwa uma okuqukethwe komswakama kuphezulu kakhulu, ukusetshenziswa kwamandla kuzokwenyuka, futhi ivolumu nayo izokwandiswa, ngokuvamile, ama-pellets azoba nendawo enzima, futhi ezimweni ezinzima, izinto zokusetshenziswa zingase ziqhume kusukela ekufeni kwe umshini we-pellet. Wonke amazinga e-pellet akhombisa ukuthi umswakama ongcono kakhulu wamapulangwe okhuni ungama-8%, kanti umswakama ongcono kakhulu wezinhlamvu ze-biomass pellets ngu-12%. Umswakama we-pellet ungalinganiswa imitha yomswakama.

Ukuminyana kwamapulangwe okhuni kungenye yezicaciso ezibaluleke kakhulu, ngokuvamile zingahlukaniswa zibe ukuminyana kwenqwaba kanye nokuminyana kwamapellets. Ukuminyana ngobuningi kuyimpahla yezinto eziyimpushana, njengama-pellets, ifomula inani lezinto eziyimpushana ezihlukaniswa ngevolumu eziyidingayo. Ukuminyana ngobuningi akuthinti nje kuphela ukusebenza komlilo kodwa nezindleko zokuthutha kanye nezindleko zokulondoloza.

Ngaphezu kwalokho, ukuminyana kwama-pellets kuphinde kube nomthelela wokuminyana kwawo ngobuningi nokusebenza kokuvutha, ukuminyana okuphezulu enakho, isikhathi eside sokuvutha okuzohlala isikhathi eside.

Ukuqina komshini nakho kuyipharamitha ebalulekile. Ngesikhathi sokuthutha nokugcinwa, ama-pellets ane-mechanical durability ephansi awonakaliswa kalula, azokwandisa okuqukethwe kwe-powder. Phakathi kwazo zonke izinhlobo zama-pellets e-biomass, ama-pellets ezinkuni agcina ukuqina okuphezulu kakhulu, cishe u-97.8%. Qhathanisa nawo wonke amazinga e-biomass pellets, ukuqina komshini akukaze kube ngaphansi kwama-95%.

Kubo bonke abasebenzisi bokugcina, inkinga ethinteka kakhulu ukukhishwa kwegesi, okuhlanganisa i-Nox, i-Sox, i-HCl, i-PCCD (i-polychlorinated dibenzo-p-dioxins) kanye nomlotha wendiza. Okuqukethwe kweNitrojeni nesibabule kuma-pellets kunqume inani le-Nox ne-Sox. Ukwengeza, inkinga yokugqwala inqunywa okuqukethwe kwe-chlorine. Ukuze kube nokusebenza okungcono komlilo, zonke izindinganiso ze-pellets zincoma okuqukethwe kwezakhi zamakhemikhali eziphansi.
