Fuel saving in coal-fired power plant with augmentation of solar energy

In today´s world, electricity is mainly generated from coal based thermal power plants that used coal as its primary fuel. In spite of an increase of the renewable power into the grid, Coal based Thermal power plants are going to rule the power generation sector in the future to meet the fast growing power needs of the country. Solar energy is one of the easily available sources of renewable energy and could be used to increase the effectiveness of steam power plants. This paper establishes that the fuel saving in coal-fired Power plant by integrating solar energy to increase the temperature of the feed water entering the boiler. As a result, the amount of fuel required to heat the feed water within the boiler to produce steam is reduced. This plant model incorporates a field with solar Fresnel collectors that directly heats boiler feed water. The proposed plant model modification saves substantial fossil fuel input reduction. The best results can be acquired when the group of high pressure heaters (HPH) is replaced by solar field and feed water temperature exceeds its original design value. So it required less amount of heat input from the boiler. A pulverized coal power plant is one of the main CO2 release resources. The integration of the solar field into a pulverized coal power plant assists it to reduce the coal consumption and CO2 emissions.
