Pulverized Coal System Advantages and Disadvantages
202178 Advantages of pulverized coal firing. (1) Greater surface area per unit mass of coal allows faster combustion reactions because more carbon becomes exposed to heat and oxygen. This reduces the excess air needed to complete combustion. (2) Less excess air is required for complete combustion because of greater surface area of fuel exposed.
