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

Firing Western Sub

The 506 Crusher Dryer is a constant speed, swing hammer type coal crusher driven by a 75 hp, 880 rpm motor. It simultaneously crushes and dries all of the surface moisture in the coal and some of the inherent moisture before discharging the coal/ air mixture to the Ball Tube Mill for final pulverization.

Overheating Electric Motors: A Major Cause of Failure

Apr 01, 2003For example at a coal-fired power plant in the United States, a 7000 hp 6.6kV motor was running with only 7 percent overcurrent, but an 8 percent overvoltage. Two identical applications had undergone unscheduled outages in the previous 12 months. A mild overload was identified by examining the stator current of this motor.

12.2 Coke Production

Coal is usually received on railroad cars or barges. Conveyor belts transfer the coal as needed to mixing bins where the various types of coal are stored. The coal is transferred from the mixing bins to the coal crusher where it is pulverized to a preselected size between 0.15 and 3.2 mm (0.006 and 0.13 in.).
