An investigation of performance characteristics and energetic
Coal-fired power plants play an important role in the world-wide power generation and meet about 40% of total consumption. Coal-fired power plants are complicated engineeringPulverized coal is used in modern thermal power plants. It is a powdered form of coal i.e., coal that is grounded into a dust-like size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning Advantages and Disadvantages of Pulverized Coal Firing

Coal dust
Energy generation. For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation.Pulverized coal is a significant dust explosion hazard, as large quantities are Reduction of Auxiliary Power of In-house HT Equipment in Thermal Power Plant by Energy Conservation.

PRACTICAL ASSESSMENT OF GRINDING CAPACITY AND POWER
thermal power plants to provide achieving higher efficiencies and increase of unit's power. One of the most important limitations to achieve maximum possible capacity at coal-fired thermal power plants is grinding capacity of mills for pulverized coal preparation. Coal grindability directly affects grinding capacities, therefore it is keytime on-site plant data. 2. COAL MILL MODELLING. In thermal power plant, pulverization of coal is carried out by coal mill. Raw coal is moved from the storage to the mill by conveyor mechanism. The type of coal mill envisaged for our model is bowl mill which is shown in Fig.1.
