Flue-gas desulfurization - Wikipedia

The process comprises the steps that coal boiler fuel gas is subjected to preliminary denitrification through an SNCR denitrification system and enters into a gas duct, dust in the fuel gas is removed through a dedusting system, secondary purification of the fuel gas is achieved by jetting dry powder absorbent into the gas duct, and the purified fuel gas is filtered through a filtration system and …

How to Desulfurize Coal Fired Boiler

Kefid 13:31:21. There are many desulphurization methods for coal fired boilers, but there are three kinds of commonly methods, pre-combustion desulfurization, desulphurization in the furnace and flue gas desulphurization, and the most widely used is desulfurization in the furnace. ZBG mainly adopts furnace desulphurization instead of flue gas desulfurization, because it is selected from the cost budget of the customer and combined with the design structure of the boiler …
