• Abstract

Efficiency Improvement, Emission Control and Energy Saving i.e. Fuel Consumption (EEE) these three factors are play a very key role in every power generation Industries but as per the Surveys majority of industries world over are still failure to achieve these factors at a time once the industries are really ignore these factors, future generation face a lot of problem so theses mainly concentrate on this area to saving this EEE at a time with some endless natural resources i.e. solar energy. A solar thermal assisted NGCC power plant was developed to investigate the impact on plant efficiency, output and CO2 emission with addition of solar thermal energy. An exemplary NGCC power plant was selected as Base Case of this study it is a Saudi Electricity Company PP12 Combined Cycle Power Project. Here I conducted an audit to know about the efficiency of power plant and identify, where the losses located and reasons for that & Find the end solutions to that problem. The power plant capacity is 2050.9 MW. In this Model a solar thermal energy input of 26 MW to the Heat Recovery Steam Generation (HRSG), the duct firing should be shut off, up to 2350 kg/h natural gas would be saved and 6.5 t/hr. CO2 emission would be eliminated. However, there would also be some loss in power from combined cycle i.e. approximately 4.08 MW. Another solar input approach shows 14.30 MW additional electricity would be generated with 42 MW solar thermal addition. The thermodynamic analyses in this theses demonstrated the possibilities to utilize the solar thermal energy to reduce fuel consumption and CO2 emission at the same time to increase the efficiency of a NGCC power plant.
