THERMODYNAMIC ANALYSIS OF SOLAR-AIDED THERMAL POWER PLANT

Abstract

In these days when every country in the world are very much serious about the economic and environmental issues, every country wants to grow up economically with increase of energy consumption and wants to keep the environment pollution free. At this position use of only coal based thermal power plant is not significant. Seeing the harmful effect to environment it is going to be completely obsolete in coming hundred years. At these days innovative techniques and better technical solutions are coming up to reduce pollution due to emission from any type of plants or vehicles. Which means many research works to reintegration of these thermal power plants with alternative renewable energy sources are growing up at this moment. Out of many solutions this work indicates the possible way of generation of power from a coal based thermal power plant integrated with indirect solar heating by using solar heater to increase the annual power output from the steam power plant. Parabolic trough solar heaters are installed in position of water circuit to increase the quality of the steam generated. The net power output is calculated by commercially available „EES‟ software upon mass & energy balance to each and every component of solar aided steam power plant. Annual power output of the solar aided thermal power plant is calculated and shows that although the investment cost for power generation is increased but the annual coal consumption is become decreased which saves fossil fuels and extra invested cost can be compensated within some years.
