Kugwira ntchito mkati mwa boiler kumakonda kusinthasintha kwamphamvu.Titha kugwiritsa ntchito mokwanira ubwino wa fluidized bedi kuyaka luso mu

kusinthasintha kwamafuta, ndikuyamba kupanga ndikuwongolera njira yowonera ndi kudyetsera kutengera chowotchera chamadzimadzi.

4, Malingaliro pazatsopano zodziyimira pawokha komanso chitukuko chaukadaulo wopangira mphamvu za biomass

Mosiyana ndi magwero ena a mphamvu zongowonjezwdwa, kutukuka kwaukadaulo wopangira magetsi ku biomass kudzangokhudza phindu lazachuma, osati

anthu.Panthawi imodzimodziyo, kupanga magetsi kuchokera ku biomass kumafunanso mankhwala osavulaza komanso ochepetsedwa a zinyalala zaulimi ndi nkhalango ndi zapakhomo

zinyalala.Phindu lake la chilengedwe ndi chikhalidwe chake ndi lalikulu kwambiri kuposa mphamvu zake.Ngakhale zabwino zomwe zimadza chifukwa chakukula kwa biomass

ukadaulo wopangira magetsi ndi wofunikira kutsimikizira, zovuta zina zaukadaulo pazopanga zopangira mphamvu za biomass sizingakhale bwino

zoyankhidwa chifukwa cha zinthu monga njira zoyezera mopanda ungwiro ndi miyezo ya biomass kuphatikiza mphamvu zamagetsi, kufooka kwachuma chaboma

thandizo, ndi kusowa kwa chitukuko cha matekinoloje atsopano, zomwe ndi zifukwa zochepetsera chitukuko cha mphamvu zopangira magetsi.

tekinoloje, Chifukwa chake, njira zoyenera ziyenera kutsatiridwa kuti zilimbikitse.

(1) Ngakhale kuyambika kwaukadaulo ndi chitukuko chodziyimira pawokha ndi njira zazikulu zopangira mphamvu zapanyumba

makampani opanga, tiyenera kuzindikira momveka bwino kuti ngati tikufuna kukhala ndi njira yomaliza, tiyenera kuyesetsa kutenga njira yachitukuko chodziyimira pawokha,

ndiyeno nthawi zonse kupititsa patsogolo matekinoloje apakhomo.Pakadali pano, ndizofunikira kwambiri kupanga ndikusintha ukadaulo wopangira magetsi a biomass, ndi

matekinoloje ena omwe ali ndi chuma chabwino angagwiritsidwe ntchito malonda;Ndi kusintha kwapang'onopang'ono ndi kukhwima kwa biomass monga mphamvu yayikulu ndi

ukadaulo wopangira mphamvu za biomass, biomass idzakhala ndi mikhalidwe yopikisana ndi mafuta oyambira.

(2) Mtengo wowongolera chikhalidwe cha anthu utha kuchepetsedwa pochepetsa kuchuluka kwa magawo opangira mphamvu zowononga zinyalala zaulimi komanso

kuchuluka kwa makampani opanga magetsi, kwinaku akulimbikitsa kuyang'anira kasamalidwe ka ntchito zopangira magetsi kuchokera ku biomass.Pankhani ya mafuta

kugula, kuonetsetsa kuperekedwa kokwanira komanso kwapamwamba kwa zida zopangira, ndikuyala maziko okhazikika komanso ogwira ntchito bwino amagetsi.

(3) Kupititsa patsogolo ndondomeko za msonkho zamtundu wa biomass magetsi, kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake

kusintha, kulimbikitsa ndi kuthandizira ntchito zowonetsera zotenthetsera zinyalala zamitundu yambiri, ndikuchepetsa mtengo wake

ya mapulojekiti a biomass omwe amangotulutsa magetsi koma osati kutentha.

(4) BECCS (Biomass mphamvu pamodzi ndi carbon kugwidwa ndi luso yosungirako) wapereka chitsanzo kuti Chili zotsalira zazomera mphamvu magwiritsidwe

ndi kugwidwa ndi kusungidwa kwa carbon dioxide, ndi ubwino wapawiri wa mpweya woipa wa carbon dioxide ndi mphamvu zopanda ndale za carbon.BECCS ndi nthawi yayitali

teknoloji yochepetsera umuna.Pakalipano, China ili ndi kafukufuku wochepa pankhaniyi.Monga dziko lalikulu lazakudya komanso kutulutsa mpweya,

China iyenera kuphatikizapo BECCS mu ndondomeko yolimbana ndi kusintha kwa nyengo ndikuwonjezera nkhokwe zake zamakono m'derali.
