FGD flue gas desulfurization-manufacture,factory,supplier from China

(Total 24 Products for FGD 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.

Differences in material selection for gypsum coresHigh quality gypsum board uses high-purity gypsum ore as the raw material, while inferior gypsum board lacks control over the purity of the raw material. Low purity gypsum ore contains a large amount of harmful substances, which can greatly affect the performance of gypsum boards. Clay and salt can affect the bonding performance of paper surface and gypsum core.

Five Methods to Teach You to Identify the Quality of Gypsum Board, Not to Be Fooled1、 Whether it meets the national standard requirementsDue to the fact that most of the strength of gypsum board comes from the paper surface, which has a fiber distribution direction, the transverse and longitudinal fracture strength of gypsum board is different. The longitudinal/transverse fracture load of gypsum board must meet the requirements of the national standard GB/T9775-1999.
