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 itself.

In the three desulfurization schemes of coal fired boilers, although the desulfurization rate of the tail flue gas desulfurization is very high, the cost of one-time desulfurization equipment facilities, annual running costs of desulfurization equipment and equipment maintenance costs are very high. Therefore, the users who choose the boiler burning a lot of lignite or inferior coal, generally purchase coal fired boiler that coal adaptability, such as circulating fluidized bed boiler and chain grate boiler, and desulfurization in the furnace can meet the requirements of environmental protection. so for the vast majority of customers, the tail of the flue gas desulfurization and pre-combustion desulfurization are not economically feasible.
