Coal fired power plants are a type of power plant that make use of the combustion of coal in order to generate electricity. Their use provides around 40% of the world''s electricity and they are primarily used in developing countries.
By 1978, Congress recognized that efficiency at central power plants had stagnated and sought to encourage improved efficiency with the Public Utility Regulatory Policies Act (PURPA), which encouraged utilities to buy power from other energy producers. Cogeneration plants proliferated, soon producing about 8% of all energy in the United States.
For nearly 100 years—ever since pulverized coal combustion was adapted for power generation—GE has been a leader in coal mill technology for the power industry. That leadership continues today with the world''s largest fleet of installed power milling equipment.
Coal mill is a machine that crushes and grinds the coal briquette into pulverized coal. It is important auxiliary equipment of pulverized coal furnace. During the coal grinding process, the coal is crushed and its superficial area increases continually.

A mechanism model of coal pulverizing system is developed to calculate the coal powder flow rate entering the combustion chamber with the data of a 300MW coalfired power plant. This model is going to be used to improve the identifiion accuracy of the calorific value, which usually takes the coal flow rate entering the coal feeder as the input.
Bringing this expertise into upgrading a coal‐fired facility can be part of the program to increase boiler efficiency and reduce environmental impact. For example, when a 500 MW power plant using 50 Kg of coal per second improves its boiler efficiency by 1%, coal usage can be reduced by 0.5% per second or 43.2 tons/day (15,768 tons/year).
In a typical coal fired power plant there are five to eight coal mills which supply the burners continuously with pulverized fuel. In intended design, one or two coal mills are allowed to be out of operation to perform maintenance and the remaining mills can cover the fuel preparation need for full load operation.

In coalfired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.
