1.0 Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coal-fired thermal power plants, the raw coal is first pulverized to the shape of flour before it is force-fed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separatedFossil fuel power stations may also use a steam turbine generator, or in the case of natural gas-fired plants, they may use a combustion turbine. A coal-fired power station (Fig. 1.1) produces heat by burning coal in a steam boiler.The steam drives a steam turbine coupled to a generator producing electricity.

Working Principle of a Thermal Plant. The working fluid is water and steam. This is called feed water and steam cycle. The ideal Thermodynamic Cycle to which the operation of a Thermal Power Station closely resembles is the RANKINE CYCLE.. In a steam boiler, the water is heated up by burning the fuel in the air in the furnace, and the Abstract. Continuous variations in coal quality have a strong influence on operation of thermal power plants. However, in absence of real-time measurements of quality, the operators remain partially blind to the actual coal being consumed, leading to sub-optimal operation. A two-stage solution is proposed for real-time soft sensing of coal Real-time coal classification in thermal power plants
The coal-pulverizer is an important unit, which pre-processes coal-fuel fed to the boiler in coal-based thermal power plants. It is extremely important to comprehend the operational behavior of the coal pulverizer unit for good performance of the boiler and overall coal power-plant. This paper describes the first principle based energy and massFrom the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric Analysis of the Coal Milling Operations to the Boiler

7 BASIC POWER PLANT CYCLE RANKINE CYCLE The Rankine cycle is a cycle that converts heat into work. The heat is supplied externally to a closed loop, which usually uses water. This cycle generates about 80% of all electric power used throughout the world, including virtually all solar thermal, biomass, coal and nuclear power plants.A coal-fired power plant, also known as a coal-fired power plant, is a plant that burns heat to make steam to produce electricity. These plants, shown in Figure 1, provide approximately 40% of the world’s electricity. Coal Power Plant. A coal-fired power station or coal power plant is a thermal power station that burns coal to generateCoal Fired Power Plant Working of Coal Power Plant
Thermal Power Plant is an electric producing power plant in which fuel (such as coal, liquefied fuel, uranium, and natural resources) is used to generate heat and that heat is further utilized to heat the water to make steam and that steam is used to rotate the turbine and further electricity generates with the help of 3 phase supply generator.The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.Draught Fans Used in Thermal Power Plants Reitz India
