What is the working principle of LD desulfurization gypsum calcination system?

The working principle of LD desulfurization gypsum calcination system is to blow high-pressure air through a high-pressure fan to make solid fuel coal "fluidized" in a fluidized bed and burn in a boiling state. A lot of hot materials are accumulated in the fluidized bed, and the temperature is about 850℃- 1050℃. Boiling combustion has strong adaptability, which can not only burn high-quality fuels, but also burn all kinds of inferior fuels.

LD fluidized bed gypsum calcination technology is one of the most advanced gypsum calcination technologies in China. LD fluidized bed gypsum calciner is a new type of calciner developed on the basis of fluidized bed calciner, which can treat a large number of desulfurized gypsum, phosphogypsum and natural gypsum. The successful development of LD fluidized bed gypsum calcination technology has made industrial by-product gypsum widely used. From the perspective of industrial policy, the proper treatment and effective utilization of desulfurization gypsum and phosphate fertilizer by-product gypsum in power plants can promote the healthy and rapid development of environmental protection industry and its related industries, save natural gypsum resources and relieve the worries of production enterprises. LD fluidized bed gypsum calcination technology has been successfully applied to the production of new gypsum building materials such as powder, block and board.
