what is pulverizer in coal power plant

Video Presentation

A Coal

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.tries besides coal-fired electric power. Coal pulverizers are the notable material-handling component largely unique to coal. Elements of the Figure 3.2 Distribution of Total Equipment Costs in a Conventional Supercritical Pulverized Coal-Fired Power Plant 6% 10% 35% 18% 4% 12% 5% 3% 1% 6% 1% SOURCE: Gerdes et al., . RAND MG-3.2 ... · 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.

Improving Coal Pulverizer Performance and Reliability

 · The purpose of a pulverizer in a coal fired boiler: To supply pulverized coal to the boiler as per requirement of steam generation. Transport the pulverized coal from pulverizer to the burners in the boiler. To remove moisture in coal to an acceptable level for firing in boiler. To remove high density inorganics from coal during pulverization.Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in accordance with a ...type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe.
