one of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. the interior of the mill rotates and the plates located on the inside grind the coal into a small size powder. during that process the plates within the mill slowly get depleted and the productivity of the mill gradually de-creases until it becomes completely dysfunctional (figure 1).
2.coal 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 burner panels.
in coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. the coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. vertical coal mill for coal grinding in cement plant
modifications and closer control of coal mills allows operation at lower load levels. combustion system requirements. the fineness of the coal powder and the uniformity of the coal flow sent to the burners are crucial parameters to achieve an effective combustion in coal-fired power plants. coal pulverisers or coal mills are the heart of a pcf boiler.
