• coal utilization

    Pulverized coal can be mixed with water and made into a slurry, which can be handled like a liquid fuel and burned in a boiler designed to burn oil. Coalwater slurry fuel (CWSF) normally consists of 50–70 percent pulverized or micronized coal, 29–49 percent water, and less than 1 percent chemicals to disperse the coal particles in the water and prevent settling of the coal.

  • Boilers machinery : Coal Pulverizer

    Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classifiion. The classifiion function plays the important role of ensuring that only fine particles of the pulverized coal ...
