Analysis of Thermal Power Plant with Variation of Different Parameter- Review Paper

The coal based thermal power plants play a very essential role to overcome power required in India. Dependency of thermal power plant in fossil fuel makes a little bit difficult, environmental impacts due to fossil fuel has been always taken into consideration. The thermal power plants are designed based on required conditions, but actually inlet conditions are not as per the designed conditions. In this paper, the author analyzes the variation of different input parameter which is also one of reason of reducing the thermal power plant performance. Turbines are designed for a particular operating conditions like steam inlet pressure, steam inlet temperature and turbine exhaust pressure/ exhaust vacuum, which affects the performance of the turbines in a significant way. Variations in these parameters affect the steam consumption in the turbines and also the turbine efficiency. The performance calculation and rectification measures are essential for performance evaluation and efficiency enhancement.
