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 ...
Originally, coal-fired power plants are designed for baseload operation which is unable to operate at a low load and change output rapidly . At present, the hard coal-fired power plants can reach the minimum load with 25–40% of nominal load and the lignite-fired power plants are usually not able to operate in <50–60% of nominal load.

The Norochcholai coal power plant shut down as a result of the recent power cut. A major electricity breakdown occurred around the island recently and that affected the Norochcholai coal power plant. However, the Ministry of Power said that the Norochcholai coal power plant was now back in operation. (Colombo Gazette) Post Views: 362.
Coal Mills are used to pulverize and dry to coal before it is blown into the power plant furnace.. Operation. 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.
Answer (1 of 2): It's more and less same as the flour mill if I talk about bowl mill. This is simplest diagram of coal mill. The crushed coal (coming from primary crusher) is stored in the cylindrical shape thing known as Bunker which is exactly on top of the mill to introduce coal into the pul...
In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.
The present day electric power generation and demand scenario requires improved control of the power plants. For better control of the coal fired power plants, proper measurement of the input energy in the form of pulverised coal flow …
For power plants currently in operation, a possible approach to cope with this issue is to introduce novel methods that increase the plant's reliability and availability.
