Do you pay attention to the particle size of coal? What problems might it cause?

Special attention must be paid, especially when the coal grinder is nearing full load

This requires attention; whether it is a fixed-bed system, a water-coal slurry system, or a dry coal powder system, there are specific requirements regarding the particle size of the coal fed in. For fixed-bed reactors, particle size directly affects the degree of reaction within the gasifier and the carbon residue content. For water-coal slurry, the particle size affects the wear of the mill’s internal components, as well as the wear of the equipment used for transporting the slurry and its operational stability. It also has a direct impact on the quality of the slurry, which in turn affects the service life of the burners. For dry coal powder, the particle size affects the service life of the mill grinders, coal powder conveying equipment and pipelines, as well as the stability of dense-phase conveying and the service life of nozzles; it can even have a direct impact on the safe operation of the gasification furnace.
