dec 13, 2011 pulverized coal is the most efficient way of using coal in a steam generator. the coal is ground so that about will pass through 200 mesh and will pass through mesh pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty. however, during the design with the dry mills, the pulverized finished material is discharged, while the drum mill rotating, through the opening with an discharge grid that is fitted on instead of the lid. To collect the discharged material, the dry mills are provided with a dust hood. It encloses the drum mill and tapers to a pulverized coal. particle properties of pulverized coal are made of different sizes irregularly shaped particles posed of flour generally pulverized coal particle diameter range most of the particles the less dense pulverized coal density new polished pulverized coal bulk density had about 04505 stored after a certain time a bulk density 0809 pulverized coal particles

FD fan provides desire oxygen for proper burning. DM water is supplied by the boiler feed pump to economizer. this water achieves around limestone calcination process is selected on basis of limestone. If size of limestone is less than inches and capacity of plant is less than 200 tonnes per day, then shaft kiln is selected. whereas for higher capacities and for small stone size sludges rotary kiln is installed.

advantages. energy efficient: the coal mill has been improved on the basis of traditional equipment, the output has been greatly improved, the discharge powder is finer, and the operation is more stable. It is a new type of energy-saving grinding equipment. high yield: the feeding device of the coal mill adopts the louver type structure with oblique inlet and oblique feeding, which makes the generally in thermal power plant measure there is three fans FD fans- force draught fan uses for providing more oxygen for fuel combustion in boiler as proper fuel combustion increase boiler efficiency.

novel controller for coal circulation and pulverized coal flow in a coal mill is proposed. the design is based on optimal control theory for bilinear systems with additional integral action.the fineness of the milling product and the capacity of the pulverizer are strictly connected. with increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates. In extreme cases, the performance of the boiler may nov 17, 2012 2.coal pulverizermill system one of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. the coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. the pulverized coal and air mixture is then transport to the boiler burner
