Sistemụ desulfurization gas na-ekpofu ihe na-agụnyekarị akụkụ ndị a bụ isi:

Sistemụ mmanụ ọkụ: Ihe mejupụtara ya bụ ọnụ ụzọ mgbaba flue gas, ụzọ mgbaba flue gas damper ọnụ ụzọ, flue ígwè, wdg, bụ nke na-ahụ maka iwebata flue gas nwere sọlfọ dioxide n'ime sistemụ desulfurization.

Usoro nkwadebe absorbent (usoro mmiri): Dị ka usoro nkwadebe limestone slurry, gụnyere limestone powder silo, vibrating hopper, akụrụngwa na-atụ, screw feeder, slurry nkwadebe igwe, wdg, eji kwadebe absorbent chọrọ maka desulfurization.

Ụlọ elu desulfurization: Ụlọ elu desulfurization bụ akụrụngwa bụ isi nke usoro desulfurization. The flue gas reacts kemịkalụ na absorbent na ụlọ elu iji nweta desulfurization mmetụta. Ụlọ elu desulfurization mmiri na-ejikarị akwa oyi akwa na akwa nkwakọba ihe iji melite arụmọrụ desulfurization.
