3 2 al pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill The coal flow is controlled by the feeder allowing coal to flow into the pulverizer mill The pulverized coal and air mixture is then transport to the boiler .
biomass pulverizing mill was also developed. 3.1 High-performance roller mills Pulverized coal fired boilers use coal of several tens of micrometers in size and then fire such pulverized coal in a suspended state inside the boiler furnace. Roller mills are commonly used as pulverizers due to their low power consumption.
maintaining the proper distribution of fuel to the burners related primarily to the boilers where the coal and biomass co-grinding is used. Changing the load of coal-mills and fuel type at the same time (i.e., different types of biomass) could result in less effective separation of pulverized fuel particles in PF distributors. Selection of an

Each type of fuel handling system consists of crushers, magnetic separators, driers, pulverizing mills, storage bins, conveyors and feeders. Figure: Pulverized coal handling plant showing all required equipment for unit and central system. The arrangement of different equipment required in both systems is shown in figure.
Pulverized fuel boiler: Coal is pulverized into a fine dust (about 0.1 mm in size), and is fed into the boiler in a stream of air. They are by far the most common boiler types for coal. These boilers can reach efficiencies of over 90% when they are well run. They can be co-fired with wood or other suitable fuels as well.
