Coal Fineness: It is understood generally that the finer we grind, the easy it is for burning. However, the fineness required will always be directed by where to fire and what type of coal it is and lastly the fineness will be dictated by the risk factor involved in finer grinding high volatile coals. The recommended fineness for coal verses volatile matter percentage is depicted in graph ...
Operation of Crushers • Ring Granulator type crushers are provided to crush the coal generally from () 250 mm/100 mm size to () 20 mm size. The following points need to be checked before returning any crushers to service: • a) The crusher shall be clear from any jamming. • b) All inspection doors are in the closed position and locked.

As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the twostage pulverizing sec tion. This section further reduces the coal size by attrition and ...

· The function of the coal fired thermal power plant is to convert the energy available in the coal to Electricity. Coal power plants work by using several steps to convert stored energy in coal to usable electricity that we find in our home that powers our lights, computers, and sometimes, back into heat for our homes. image provided by the Tennessee Valley Authority.

Generally these crushers are used before final crushers. The output size of coal affects the performance of CHP. Naturally these two hard surfaces are critical parts. One of these surfaces are known as grinding plates and other may known as rings, hammers etc. The linkage between crusher rotor and drive assembly are also critical parts. As failure of these linkages will stop crushing. ...
This type of crusher is generally used with soft materials like coal, seeds or soft metallic ores. The mechanism applied here is of Impact loading where the time of appliion of force is less than the natural frequency of vibration of the body. Since the hammers/blow bars are rotating at a very high speed, the time for which the particles come in contact with the hammers is very small, hence ...
transported to bunker via transfer house and remaining coal is stored in stockyard. The minimum stack level is maintained. This coal is reclaimed as per requirement. From the bunker the coal flows through coal mills to boiler furnace. The main aim of CHP to maintain level of coal in bunkers for smooth coal supply to boiler. Unloading Unit No 1

Function Clarifiion The deaerator is designed to remove oxygen that is dissolved in the entering water, not entrained air. Sources of "free air" include loose piping connections on the suction side of pumps and improper pump packing. Pressure Fluctuations Sudden increases in free or "flash" steam can cause a spike in deaerator vessel pressure, resulting in reoxygenation of the ...
