Ukukhula okukhawulezileyo kwemfuno yamandla ehlabathi kuvule indlela yophuhliso lwezinye iindlela zobutyebi bendalo.Nangona kunjalo, amalahle asadlala indima ebalulekileyo kumthombo wamandla ongundoqo wehlabathi.Amalahle abalelwa kwi-29% yonikezelo lwamandla ehlabathi ngo-2015, kwaye kuqikelelwa ukuba. ukuba ngo-2035, amalahle azakuba yinxalenye ye-24% yamandla. Njengemveliso ephuma kwimizi-mveliso yezixhobo zombane ezibaswa ngamalahle, isixa sothuthu lwempukane yamalahle siya kuhlala siphezulu ixesha elide.Amalahle fly uthuthuiye yaba yingqwalasela yendalo esingqongileyo ngenxa yokwakheka kwayo okuntsokothileyo kunye nonyango olungekho ngqiqweni. Kwangaxeshanye, uthuthu lwempukane yamalahle sisixhobo esinokubakho, ekufuneka sisetyenziswe ngokungxamisekileyo ngokufanelekileyo. Okwangoku, ukusetyenziswa kobutyebi bothuthu lwempukane yamalahle kubandakanya indawo ebanzi Uluhlu lwemimandla, kodwa izinga eliphezulu lokusetyenziswa kwexabiso liphantsi.Isiseko sokusetyenziswa kwexabiso eliphezulu kukufunda iipropati ze-coal fly ash.Uthuthu lwe-coal fly ash yenziwe ngamasuntswana a-amorphous spherical particles,i-carbon particles engatshiyo kunye neeminerali. Amasuntswana afana ne-mullite, iquartz, ihematite, njl. Kukho iiyantlukwano kwiipropati ezibonakalayo, ukwakheka kweekhemikhali kunye nokwakhiwa kweeminerali zothuthu lwempukane yamalahle kwiindawo ezahlukeneyo zokuvelisa. Indlela yokusetyenziswa kwayo kunye nenjongo nazo azifani. Uthuthu lungumqobo omkhulu ekusetyenzisweni kwexabiso eliphezulu.Nangona kunjalo, amacandelo aluncedo, anjengeemicrospheres ezingenanto, ikhabhoni engatshiyo, imathiriyeli yemagnethi, njl. njl -ixabiso lezinto eziluhlaza kwiimveliso eziphezulu zexabiso ezongeziweyo ezifana ne-geopolymers, i-glass-ceramics kunye ne-zeolites.Ukwakheka kweekhemikhali kunye nobukhulu besuntswana lokuqala lothuthu lwamalahle lunempembelelo enkulu kumandla e-geopolymers.Iimeko ezifanelekileyo zobugcisa kufuneka zimiselwe kwi isiseko kuqwalaselwe ngokupheleleyo iipropati ezisisiseko amalahle fly uthuthu xa ulungiselela geopolymers.Ngokokwakheka imichiza amalahle fly uthuthu,iglasi-ceramics zilungiswe ukusuka amalahle fly uthuthu ikakhulu ziqulathe iinkqubo ezimbini:CaO-Al2O3-SiO2 kunye MgO-Al2O3- I-SiO2, kodwa ukusetyenziswa kwamandla kwindlela yokulungiselela iphezulu kakhulu.Indlela yokucoca ngokuthe ngqo kunye nokusetyenziswa kwamandla aphantsi kusafuneka ifundwe ngakumbi kwaye ixhaphake. Kukho imifuniselo emininzi yesicelo ye-zeolite eyenziwe ngothuthu lwempukane yamalahle, kodwa iimvavanyo ezimbalwa zemizi-mveliso ziyenziwa. Uphando lwethiyori malunga nolungiselelo lwe-silica ye-mesoporous kunye ne-silica aerosol alikho ngokucokisekileyo ngokwaneleyo, iimeko kunzima ukuzilawula, kwaye kusekho indlela ende phambi kokuveliswa kwemveliso.
