Efficiency Analysis of the Turbine using Calorific Value Parameters for a 10 Megawatt Gas Turbine
This research is based on the analyzed thermodynamics of a gas turbine energy plant. It considered the differing operating states, i.e. the ambient temperature, the compressor outlet temperature, pressure ratio, etc. and their affective modes on thermal efficiency, turbine work, compressor work, etc. which were derived and analyzed. The Gross (higher) calorific values at constant pressure (Δh_((liq) )) heat of combustion in a flow process from state 1 to state 2 was considered and used to analyze our thermal efficiency. Ambient temperature cum air/ fuel ratio affected the turbine work, compressor work and system efficiency. In addition, the thermal efficiency nd power decreases linearly with increase of the ambient temperature. However, the efficiency analyzed when the calorific parameters were considered was higher than the efficiency when the basic thermodynamic theories (first and second law principles) were used. The first ranges between 31% to 33, while the second ranges between 28% to 32% under the same ambient temperature conditions.
