TENORM: Coal Combustion Residuals | Radiation Protection | US EPA

In a typical coal-fired boiler, coal is burned and the heat is extracted to generate steam. The steam is used to drive a turbine, which in turn, drives an electrical generator. Low pressure steam leaving the turbine is fed to a cooling system which extracts any residual heat and condenses the steam back to water.

Coal for Electricity Generation, Kentucky Geological Survey

How coal is used to generate electricity in a conventional coal-fired power plant with a pulverized coal boiler. Emissions Control. In the United States, gases produced by the combustion of coal in the boiler (called flue gas) must be treated to remove air pollutants before they can be released to the atmosphere through the power-plant stack.

Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.
