Coal power and combustion. Quarterly report, January--March 1977
ERDA's coal combustion and power program has focused on two major areas: Direct combustion of coal and advanced power systems. Efforts in the area of direct combustion are concentrated on: Development of atmospheric and pressurized systems capable of burning high-sulfur coal of all rank and quality in fluidized-bed combustors; development of advanced technology power systems to generate power more economically than present technology permits while using medium- and high-sulfur coal in an environmentally-acceptable manner; development of the technology enabling coal-oil slurries to be substituted as feedstock for gas or oil-fired combustors; and improvement of the efficiency of present boilers. Compared with conventional coal-fired systems, fluidized-bed combustion systems give higher power generation efficiencies and cleaner exhaust gases, even when burning high-sulfur coals. If the fluidized-bed system is pressurized, additional economies in capital and operating costs may be realized. The benefits from high-pressure combustion are a reduction of furnace size due to decreased gas volume and better sulfur removal. High-pressure combustion, however, requires the development of equipment to clean the hot combustion products to make them suitable for use in power generation turbines. The advanced power systems program is directed toward developing electric power systems capable of operating on coal or coal-derived fuels. These systems involve the use of high temperature gas turbines burning low-Btu gas and turbine systems using inert gases and alkali metal vapors. Some 25 projects in these areas are described, including a brief summary of progress during the quarter. (LTN)
