Kungakhathaliseki ukuba uceba ntoni: ukuthenga iipelisi zokhuni okanye ukwakha isityalo somthi, kubalulekile ukuba ukwazi ukuba zeziphi iiplanga zokhuni ezilungileyo kwaye zibi.Ngombulelo kuphuhliso loshishino, kukho ngaphezu kwe-1 imigangatho yeeplanga zokhuni kwiimarike.Umgangatho weplanga lomthi luphawu olusekiweyo olumanyeneyo lweemveliso kushishino.Ekubeni imigangatho yase-Austrian (ÖNORM M1735) ishicilelwe kwi-1990, amalungu amaninzi e-EU aphuhlise imigangatho ye-pellets yelizwe, njenge-DINplus (eJamani), i-NF (eFransi), i-Pellet Gold (eItali), njl. kwihlabathi, iKhomishini yaseYurophu iseke imigangatho ye-EU (CEN TC335- EN 14961) ye-fuel eqinile, esekelwe kwimigangatho yase-Austrian (ÖNORM M1735).

Ngokusekwe kuyo yonke imigangatho ekhoyo yeepelisi zokhuni, sikubonelela ngengcaciso ephezulu ukukunceda ukuba uchonge iipeliti zomthi ezikumgangatho ophezulu.

Sishwankathele zonke izinto ezibalulekileyo kuwe ukuba ukhawuleze ujonge ukuba ilungile kangakanani ipellet yomthi.Landela la manyathelo alandelayo:

Ezona dayamitha zeepellet zomthi zixhaphakile yi-6mm kunye ne-8mm.Ngokubanzi, okukhona i-diameter encinci injalo, kokukhona ukusebenza ngcono kwe-pelletizing enayo.Kodwa ukuba ububanzi bungaphantsi kwe-5mm, ukusetyenziswa kwamandla kuyenyuka kwaye umthamo unqatshelwe.Kwakhona, ngenxa yokuma kweepellets, umthamo wemveliso ucinezelekile, ulondoloze indawo yokugcina.Ngaphezu koko, kulula ukuthutha, ngoko ke iindleko zokuthutha ziphantsi.Phakathi kwayo yonke imigangatho ekhoyo, kukho ukuqonda okuqhelekileyo malunga neempazamo zobubanzi, okungekho ngaphezu kwe-1mm.

Ngokwayo yonke imigangatho yeepelisi zokhuni, umgangatho womswakama ofunekayo ufana, akukho ngaphezu kwe-10%.Ngokobuchwephesha, ngexesha lenkqubo, isiqulatho samanzi sisibophelelo kunye ne-lubricant.Ukuba umgangatho womswakama uphantsi kakhulu, iipelisi azikwazi ukwandiswa ngokupheleleyo, ngoko ke iipelisi zingaba yi-deformation, kwaye ubuninzi buphantsi kuneepilisi eziqhelekileyo.Kodwa ukuba umthamo womswakama uphezulu kakhulu, ukusetyenziswa kwamandla kuya kwandiswa, kwaye umthamo uya kwandiswa, ngokuqhelekileyo, iipellets ziya kuba neendawo ezinqabileyo, kwaye kwiimeko ezinzima, izinto eziluhlaza zinokuthi ziqhume kwi-dies of the dies of the ilitye lokusila.Yonke imigangatho yeepellet ibonisa ukuba okona kufuma kwiplanga leplanga yi-8 %, kwaye okona kufuma kwi-grain biomass pellets yi-12%.Ubumanzi bepellet bunokulinganiswa ngemitha yokufuma.

Ubuninzi beepelisi zokhuni yenye yezona zinto zibalulekileyo, ngokuqhelekileyo zinokwahlulwa zibe yi-bulk density kunye ne-pellets.Ubuninzi be-bulk yipropathi yezinto zomgubo, ezifana neepelisi, ifomyula ngubuninzi bezinto zomgubo ezahlulwe ngumthamo ofunekayo.Ukuxinana kwesambuku akuchaphazeli kuphela ukusebenza kokutsha kodwa neendleko zothutho kunye neendleko zokugcina.

Ngaphaya koko, ukuxinana kweepellets kukwayimpembelelo yobuninzi bayo kunye nokusebenza kokutsha, ukuxinana okuphezulu okunayo, ixesha elide lokutsha liya kuhlala.

Ukuqina komatshini kwakhona ipharamitha ebalulekileyo.Ngethuba lokuthutha kunye nokugcinwa, iipelisi ezinokuqina okuphantsi komatshini zonakaliswa lula, ziya kwandisa umxholo we powder.Phakathi kwazo zonke iintlobo zeepellet ze-biomass, iipelisi zokhuni zigcina ukuqina okuphezulu komatshini, malunga ne-97.8%.Thelekisa yonke imigangatho ye-biomass pellets, ukuqina koomatshini akunakuze kube ngaphantsi kwe-95%.

Kubo bonke abasebenzisi bokugqibela, eyona ngxaki ichaphazelekayo yi-emissions, equka i-Nox, i-Sox, i-HCl, i-PCCD (i-polychlorinated dibenzo-p-dioxins) kunye ne-fly ash.Iziqulatho zeNitrogen kunye neSulfur kwiipellets zinqume inani leNox kunye neSox.Ukongezelela, ingxaki ye-corrosion inqunywe ngumxholo we-chlorine.Ukuze ube nokusebenza kakuhle kokutsha, yonke imigangatho yeepellets incoma umxholo wemichiza ephantsi.
