The coal-fired Navajo Generating Station, about 250 miles east of Las Vegas in Northern Arizona, was the largest power plant in the western U.S. until it closed last November. Built in the early 1970s, it leased its 1,786-acre site from the Navajo Nation and payed about $52 million per year in wages to 538 employees, 90 percent of whom were Navajo.

The plant uses low sulphur and low bitumen coal (pulverised for burning) to minimise pollution. The resulting ash is valuable for the cement industry, and most is caught by electrostatic precipitators. Dust control is also an important feature (the conveyor belt is covered and sprinkler systems remove up to 99.9%).

Get priceWhat is coal used for? Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.

Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.This occurs when water reaches its critical point under high pressures and temperatures, specifically at 22 MPa and 374 o C.
