Steam Power Plants 103 power plants, power is generated by alternately vaporizing and condensing a working fl uid (in many cases water, although refrigerants such as ammonia may also be used) [1]. There are four processes in the Rankine cycle, each changing the state of the working fl uid. These states are identifi ed by number in Fig. 1.
Power plant ball mill system. The schematic diagram of ball mill system is shown in Fig. 1. When the raw coal is fed into ball mill, the hot air and recycle air are blown to dry and deliver the coal powder. The accepted powder is stored in the bunker, and the unqualified powder is sent back into ball mill for further grinding.

Introduction. Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
Flow Diagram of a Steam Thermal Power Plant. March 7, 2021. February 24, 2012. by Electrical4U. A thermal power generating plant works based on the Rankine Cycle. There are mainly three primary inputs given to thermal power generating plants for producing electricity. These three most essential elements are coal, air, and water.

Credit: Georgia Power. A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to ...
The major advantage of this type is that the coal can be carried directly into the powerhouse up to the point of consumption. 5. Transportation by Pipeline. In this method, the coal in the form of slurry is directly supplied from the remote mines to the strategically located thermal power plants through pipelining.
