Jan 15, 2019 A pulverized coal-fired boiler is an industrial boiler that generates thermal energy by burning pulverized coal. How does a steam boiler work In pulverized coal fired boiler,The coal is pulverized to a fine powder, so that less than 2 is 300 micro meter and 70 75 is below 75 microns.
Aug 29, 2010 Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal
The classification function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler. Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the relative balance of centrifugal force and centripetal force produced by a blade ...
