Limestone Makes for Cleaner Coal

For older coal-fired power plants this included installing scrubber systems in the smokestacks to filter sulfur from the exhaust. “In 1985, Plains Electric built a power plant in nearby Prewitt, New Mexico and the project manager needed a source for limestone that would pass the qualifications required for the power plant emissions,” he says.

lowest uncontrolled dust emissions due to the large lump feed, the relatively low air velocities, and the slow movement of material through the kiln. In coal-fired kilns, the properties of the limestone feed and the ash content of the coal can significantly affect PM emissions. Some sort of particulate control is generally applied to most kilns.

Carbon Dioxide Emission Factors for Coal

The high carbon dioxide emission factor for anthracite reflects the coal's relatively small hydrogen content, which lowers its heating value. (11) In pounds of carbon dioxide per million Btu, U.S. average factors are 227.4 for anthracite, 216.3 for lignite, 211.9 for subbituminous coal, and 205.3 for bituminous coal. Table FE4.
