1. Introduction. In order to react effectively with oxygen from the air in a gas stream in coal power stations, typically the coal particle size needs to be at least 70% finer than 75 μm, with 99.5% of the particles needing to be finer than 300 μm.Grinding of coal to this level of fineness is referred to as coal pulverisation.
