Impahla yokuhlunga esezingeni lokushisa eliphezulu yenziwa ngemicu yamakhemikhali ekwazi ukumelana nokushisa okuphezulu. Ngokwezinto ezahlukene, lolu chungechunge lunganelisa noma yisiphi isidingo sokuhlunga umusi womoya ongaphansi kwezinga lokushisa elingu-260°C. Lolu chungechunge lunezici ezinhle zokumelana nokugqokwa nokugoqwa, kanti ezinye zinezici ezinhle zokumelana ne-acid, i-alkali nokumelana nokuhlukana kwamanzi, ezisetshenziswa kabanzi emikhakheni ye-cement kiln, i-blast-furnace, i-sinter fume embonini yensimbi, i-boiler yokushisa amalahle esiteshini samandla, imboni yamakhimikhali, imboni ye-asphalt. imboni ye-carbon black kanye nokushiswa kukadoti, njll.
