Limestone desulfurization agent powder production process

Limestone powder production process for FGD coal powder furnace flue gas desulfurization

The coal powder furnace has sufficient combustion and usually uses tail flue gas desulfurization directly. The limestone powder used for desulfurization requires a particle size of 250 mesh or 325 mesh (45 μ m) 325 mesh limestone powder has better desulfurization effect.

In recent years, with the increasing demand for the fineness of limestone powder and the need for energy conservation and emission reduction, more and more power plants have started to use the Dawn Heavy Industry European version grinding machine scheme for preparing limestone powder through flue gas desulfurization.

Integrated powder production process of desulfurizer inside and outside CFB furnace

Based on the desulfurization characteristics of CFB boilers, Dawn Heavy Industry has optimized the entire system of the European version powder mill and launched an integrated powder production process for desulfurization agents inside and outside the circulating fluidized bed (CFB) furnace.

This process can simultaneously produce two different particle sizes of limestone desulfurizer powders, 1mm-0.045mm (for desulfurization inside the furnace) and 0-0.045mm (for desulfurization outside the furnace), meeting the demand for simultaneous supply of powder inside and outside the furnace. One machine has multiple functions, which can greatly save equipment investment, production land, and personnel expenses.
