Coal Fired Power Plant Pulverizer Gear Coupling Failure

Has a slight decrease with pulverizer newness for bituminous coals Conversely explosion frequency increases with pulverizer newness for subbituminous coals Coal Type The subbituminous coals have explosion frequencies of about twice those of bituminous coals The explosion values of lignite coals were ignored due to the extremely small.Apr 20 2015 Large electric motors use a worm gear arrangement to drive the coal pulverizers and a blower that sends the pulverized coal to the furnaces The shafts of the motor must be mechanically connected to the worm gear and blower The worm gear is a relatively small yet vital component If it fails the pulverizers and blowers can no longer operate.

Safety System For Coal Pulverizers

Pulverized coal Pulverized coal combustion is widely used in large power stations because it offers flexible control In this method coal is finely ground so that 70 to 80 percent by weight passes through a 200 mesh screen The powder is burned in a combustion chamber.Process of coal pulverizer The finer the grinding of coal the efficient its combustion the total time required from entry of a coal particle to a furnace to combustion of the particle is very short this time however is dependent on various factors the heart of a pulverized coalfired boiler is the pulverizer also known as the mill.
