Abstract

This communication presents thermodynamic methodology for the performance evaluation of combustion gas
turbine cogeneration system. The energetic and exergetic efficiencies have been defined. The effects of process steam
pressure and pinch point temperature used in the design of heat recovery steam generator, and HRSG on energetic and
exergetic efficiencies have been investigated. From the results obtained in graphs it is observed that the power to heat ratio
increases with an increase in pinch point and the first-law efficiency and second-law efficiency increases with an increase in
pinch point from part load to full load. The power to heat ratio, first-law efficiency and second-law efficiency increases
significantly with increase in process steam pressure, but fuel air ratio and specific fuel consumption the decreases with the
same. This results also show that inclusion of HSRG, provide significant improvement in electrical power output, process
heat production, fuel-utilization (energetic) efficiency and second-law (exergetic) efficiency. This methodology may be quite
useful in the selection and comparison of combined energy production systems from thermodynamic performance point of
view.
