Coal Processing

Coal Processing

 · Describing and eliminating the health hazards of coal processing requires an understanding of the nature of the raw materials, products, byproducts, the type of pollutants produced, the design of the plant and its operating methods (Wadden, 1976).The structure of coal was described in Chapter 6 and is thought to be a highly linked amorphous polymer consisting of aggregates connected .

Coal Crushing. It has been stressed that the coal supplier should initially crush the materials to a maximum size such as 300 mm, but they may be something else depending on the agreement or coal tie up. To circumvent the situation, the CHP keeps a crushing provision so that coal bunkers receive the materials at a maximum size of about 20–25 mm. The unloaded coal in the hoppers is ...

Coal pulverisation | The Nature Of Science

Coal pulverisation | The Nature Of Science

Crushing the coal into fine powder makes it easier to burn it more completely (in fact, powdered coal is explosive when airborne!) This is important, because the act of burning coal requires the use of energy, so by making the coal easier to burn, less heat energy is being used to access the energy locked within the coal. It is also important to ensure the coal can be burned more completely ...
