How Does a Coal Power Plant Work? - Bright Hub Engineering

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2. Learn how the process works as well as interesting

Determination of Flue Gas Desulfurization by Analyzing

A flue gas desulfurization (FGD) processing unit, generally known as a scrubber, eliminates sulfur dioxide (SO 2) from the exhaust flue gases in power plants in which coal is burnt. Airborne SO 2 forms sulfuric acid (H 2 SO 4 ) by oxidizing within airborne water droplets, resulting in "acid rain".

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.
