Y. Yan, in Advanced Power Plant Materials, Design and Technology, 2010 10.1 Introduction. Coal-fired power stations are burning an increasingly varied range of fuels and fuel blends, including sub-bituminous and lower volatile coals and biomass of varying composition and combustion properties, under tight economic and environmental constraints. Since existing coal-fired plants are not designed ...
Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
This type of mill uses a central horizontal shaft which has a number of arms, and a beater of different design is attached to these arms to beat the coal to be pulverized. High speed impact mills are mainly used in pulverizing lignite. Today all boiler designers opt to use ball or vertical spindle mill for coal other than lignite.
Fuels used in the power plants. The important fuels used in the power plants like, coal, diesel, steam, uranium, etc. are also clearly described here.

Types Of Mills Used In Power Plant . Basically the turbines are used to convert the wind energy into electrical energy with the help of a generator. It extracts the energy from the wind and converts it into mechanical energy and then this mechanical energy is used to derive a generator and we get electricity.
The power plant's net efficiency is simply the heat content of electricity (3600 kJ/kWh) divided by the heat rate (kJ/kWh) (see Equation 2). (2) The power plant's heat rate depends on the fuel type used and the specific power plant design. All the heat put into the plant that is not converted into electricity has to be dissipated somehow to the
