The coal/water boiler at the Pittsburgh Energy Technology Center is a 700 horsepower boiler which has been operating since 1978. The objective of the unit is to determine the feasibility of converting oil-fired utility boilers to use coal water slurry as fuel. The feedstock coal for the PETC coal/water boiler is pulverized and mixed with water at a ratio of 60% coal to 40% water. The slurry is then pumped to the boiler and sprayed into the firing chamber using conventional oil-firing equipment. Currently, parametric studies are being conducted to determine the effects of changing combustion conditions. The US Department of Energy, Laramie Energy Technology Center, has contracted with Versar Inc., of Springfield, Virginia, to collect, containerize, and distribute samples of coal feedstocks and resultant solid wastes from utility plants and emerging energy technologies. Engineering Science (ES) of Atlanta, Georgia, has been contracted to assess the potential range of impacts of the Resource Conservation and Recovery Act (RCRA) on the utility sector and emerging energy technologies. Through the cooperation of the DOE, Pittsburgh Energy Technology Center staff, Versar was provided with samples of the solid waste materials generated by the coal/water boiler as well as a detailed analysis of the coal feedstock. Versar's responsibilities at this facility included the following: (a) Containerization - After samples are collected and processed (i.e., dewatered, crushed, blended, and dried), specimens are placed in randomly-labeled containers; and (b) Distribution of samples - Specimens are sent to a minimum of two commercial laboratories for analysis. The overall objectives to provide samples of feedstock materials and solid wastes from 25 utility sites and fossil energy emerging technologies distributed across the country.
