Pulverized Fuel Handling Systems: Unit, Central

The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is separated in the cyclone separator.

1.7 Lignite Combustion

Pulverized coal units have been designed for both wet and dry bottoms, but the current practice is to design only dry bottom furnaces. Another type of boiler firing lignite is the cyclone burner, which is a slag-lined high-temperature vortex burner. The coal is fed from the storage area to a crusher that reduces the lignite into particles of

24.02.2012· Disadvantages of Pulverized Coal Firing. The initial investment in pulverized coal firing system is more compared to solid firing system. The running cost is also higher. The pulverized coal produces fly ashes. Removal of ash grain from the exhaust gases is always expensive as it requires an electrostatic precipitator.

Ignition temperature of pulverized coal particles

Laboratory measurements of the visual and combustion sequences during the ignition of pulverized coals, chars, and petroleum coke are reported. Two experimental techniques—the first using a pulse of coal and the second, a continuous flow of coal and air in near stoichiometric proportions—are shown to give similar gas temperatures for the onset of flashing.
