Chapter 3 Properties of We Energies Coal Combustion Products Fly ash and bottom ash produced at the six coal-fired power plants that are owned and operated by We Energies have been subjected to extensive tests for physical and chemical properties. The type of coal, percentage of incombustible matter in the coal, the pulverization process, furnace types and the efficiency of the combustion process determine the chemical composition of the coal ash. Another factor affecting the quality of coal ash is whether the power plant is base loaded or frequently being brought in and out of service. A base loaded plant operates at consistent temperatures and combustion rate. Plants that are frequently changing load or coming in and out of service tend to produce more variability in coal ash characteristics. The use of low NO x burners at power plants has generally resulted in an increase in loss on ignition and carbon content in the fly ash. Likewise, many SO x reduction processes result in higher sulfur compounds in the coal ash. Figure 3-1: Fly ash particles are spherical and average about 10 microns in diameter We Energies purchases coal from several mines. Several factors affect the selection of coal source, but the quality and cost of coal are two very important considerations. The consistency of fly ash does not change significantly if the coal used in the plant is from a single geological formation or from a consistent blend of coals. But when coal sources change, the chemical and physical properties of the fly ash may change significantly if the type or chemistry of coal is switched. At times, coal from different sources may be blended to improve air emissions, to reduce generation costs, to increase the efficiency of combustion and/or to improve the quality of fly ash generated. 33 We Energies Coal Combustion Products Utilization Handbook
