Coal-fired power operators continue to look for ways to increase the efficiency and extend the working lives of their plants by improving operational flexibility and reducing environmental impact. Two possible options are explored here: combining solar energy with coal-fired power generation, and cofiring natural gas in coal-fired plants.

This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.

Advantages of coal-fired power plant: It's known that coal is the most widely used fuels for generating power and electricity around the world which means that the coal_fired power plant has many advantages as: It's abundant and easy to burn. It doesn't depend on the weather or existing climatic conditions for mining coal.
