THERMODYNAMIC AND ENVIRONMENTAL MODELLING OF THE AZURA EDO POWER PLANT

In order to address the growing global energy demand and reduce the environmental impact from operating gas turbine power plants, the performance and how to improve existing gas turbine power plants need to be studied. In view of this, this research work aims at carrying out the thermodynamic and environmental analyses of Azura Edo Power Plant for design and off-design conditions. Ebsilon Software is a commercially accepted energy and mass balance tool for power plant modelling. The performance of the Azura Edo Power Plant at design and off-design conditions were modelled using Ebsilon Software and the simulation exercise was validated. Energy, exergy and environmental analyses were conducted using operating data collected from the power plant to evaluate the thermal efficiencies, heat rate, energy losses and exergy destruction of each major component of the power plant and carbon dioxide emission rates with the aid of MATLAB software. The effects of ambient air temperature on the thermodynamic and environmental performances were carried out. Preliminary analyses of the effect of integrating an inlet air cooling system and heat recovery steam generator (HRSG) for future consideration were conducted.
