This paper presents an analysis of the fuel values of the energy resource utilized in a 710KVA steam turbine plant at Ada Palm Oil Plantation Nigeria Limited, Imo State, Nigeria using the performance data obtained from the plant operation. This is with a view of using the results obtained from the study to identify the locations and magnitudes of losses associated with the system and thus, seek for an improvement on its performance efficiency. The oil mill operates a cogeneration system using fibre and shell as fuels in the boiler to produce high pressure steam which expands through a steam turbine to produce electricity utilized at the plant. The results obtained from the analysis indicate that the theoretical combustion air requirement for the fibre and the shell are respectively 3.89kg of air/kg of fuel and 5.99kg of air/kg of fuel, while that for the entire plant is obtained as 8.96kg of air/kg of fuel. Also, the percentage excess air of 45% supplied with an actual mass of air of 13kg of air/kg of fuel supplied per kg of fuel, and 98% value of heat loss due to dry flue gas, with 0.165% of heat loss due to moisture present in air gave the efficiency of the boiler at 1.84%. From the combustion analysis, the stoichiometric air/fuel ratio required for combustion was approximately obtained as 0.068. The study identified that greater part of the total heat energy generated in the combustion chamber was not available for doing any useful work and thus formed the backdrop for the losses and low value of the boiler efficiency. In-view of these, exergy-based performance monitoring approach has been recommended in this study to assist in managing energy resources and environment better. This will be achieved by undertaking effective operation and efficient maintenance decision and strategies capable of reducing exergy destruction in power plant for energy production.
