Pulverized Fuel Boilers Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm ( in). Coal burns in suspension, like the combustion in an oil or gasfired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace
Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat''s flowshaping contour, enables recirculation patterns that .
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coalfired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.

Nov 17, 2012· coal mill/pulverizer in thermal power plants shivaji choudhury 2. Coal continues to play a predominant role in the production of electricity in the world, A very large percentage of the total coal is burned in pulverized form. Pulverized coal achieved its first commercial success in the cement industry.
Dec 13, 2011· A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only twothirds of the ball mills.
