TVA - How a Coal Plant Works

The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real-life example: The Kingston Fossil Plant near Knoxville, Tenn., burns coal to heat its boilers to about 1,000 degrees Fahrenheit to create high-pressure steam. The steam is piped to the turbines at pressures of more than

Steam For Power and Process - Babcock & Wilcox

B&W's radiant boiler designs accommodate pulverized coal, including difficult-to-burn coals, natural gas and/or oil and combustible byproduct gases. Subcritical pressures range usually 1800 to 2600 psi (12.4 to 17.9 MPa) and superheater and reheater outlet temperatures as required, usually in the range of 1000 to 1050 F (538 to 566C).
