Process of flue gas desulfurization-manufacture,factory,supplier from China

(Total 24 Products for Process of flue gas desulfurization)
If the flue gas desulfurization gypsum and coal powder from power plants are not treated in a timely and reasonable manner, a large area of land will be utilized, and even unnecessary secondary pollution will be brought to the environment. Desulfurization gypsum from power plants has the characteristics of high taste and small particles. However, with the widespread application of gypsum method and limestone/wet lime in thermal power plants in China, the production of desulfurization gypsum has rapidly increased due to its by-products.

This method is still widely used in the domestic ceramic industry.Pressure steaming method for frying pasteThis method first preheats the raw Plaster with a block size of 25-50mm after coarse crushing in hot air at 60 ℃, and then places it in a pressure cooker for 5-7 hours with saturated superheated steam at 1,3 atmospheric pressure (125 ℃). Then, hot dry gas at 200 ℃ is introduced until hot dry gas is discharged, resulting in a vapor pressure of hemihydrate Plaster.
