Basic Layout and Working of a Thermal Power Plant ...

Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage which is used when coal supply is unavailable.

Power Plant History | About | Plant Operations ...

Coal-fired boilers continued to be the campus' main source for generating power until 1988 when the first natural gas boiler was introduced, converting Vanderbilt's power plant to a dual-fueled cogeneration power plant. The cogeneration process was highly efficient, using backpressure and condensing turbines to ensure maximum performance.

How do power plants work? | How do we make electricity?

 · Types of power plants Steam turbine. Most traditional power plants make energy by burning fuel to release heat.For that reason, they're called thermal (heat-based) power plants. Coal and oil plants work much as I've shown in the artwork above, burning fuel with oxygen to release heat energy, which boils water and drives a steam turbine.This basic design is sometimes called a simple cycle.
