In a commercial coal-fired system, the coal injection to the pulverized combustor is made at ple locations of the boiler through ple injecting pipes connecting to the central coal hopper. The total feed rate to the boiler can be readily measured from the discharge rate from the central coal hopper.

PULVERIZED COAL FURNACES - Thermopedia

Pulverized coal (pulverized fuel-pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the ...

Pulverised Coal Combustion with higher efficiency ...

Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired 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.
