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

What are the factors that affect the desulfurization efficiency of limestone?
The preparation of limestone powder has become a prerequisite for thermal power desulfurization and improving desulfurization efficiency. What are the factors that affect the desulfurization efficiency of limestone? 1. Quality of limestone Normally, the CaSO4 content in limestone should be higher than 85%. If the content is too low, it may cause some problems in operation due to

Development and utilization of coal based kaolin
During the coal mining process, a large amount of coal gangue is generated. When the content of kaolin in the gangue exceeds 80%, it is called coal series kaolin, which is an important non-metallic mineral resource unique to China, with unique characteristics and broad utilization prospects. Coal based kaolin is a precious natural resource and an important non-metallic mineral. It
