Abstract

In a bid to recover lost energy in the gas turbine and improve efficiency, many modifications to power plants have been made. The COGAS plant is one of such modifications to existing power plants. Due to the high efficiency obtained from such plants theoretically, it is seen that the COGAS plant is of immense benefit for practical applications. However, there exists no chart or Table that predicts the efficiency of the COGAS plant at any operating condition since two COGAS plants of the same specification can provide different efficiencies when operated in different regions or places e.g. (Canada in winter and Nigeria in Harmattan). Thus basic parameters of the COGAS plant were examined as to further understand their effect and enhance efficiency. This analysis was achieved using VB.Net computer programming language and data collected from gas and steam turbines on industrial duty for electricity generation. The result is a Table similar to the presently existing thermodynamic steam Table which will assist designers and engineers to pick optimum parameters with a targeted efficiency and place of operation in mind.
