N2 - A thermodynamic and economic analysis of a GT10 gas turbine integrated
with the air bottoming cycle is presented. The results are compared to
commercially available combined cycle power plants based on the same gas
turbine. The systems under analysis have a better chance of competing with
steam bottoming cycle configurations in a small range of the power output
capacity. The aim of the calculations is to determine the final cost of
electricity generated by the gas turbine air bottoming cycle based on a 25
MW GT10 gas turbine with the exhaust gas mass flow rate of about 80 kg/s.
The article shows the results of thermodynamic optimization of the
selection of the technological structure of gas turbine air bottoming
cycle and of a comparative economic analysis. Quantities are determined
that have a decisive impact on the considered units profitability and
competitiveness compared to the popular technology based on the steam
bottoming cycle. The ultimate quantity that can be compared in the
calculations is the cost of 1 MWh of electricity. It should be noted that
the systems analyzed herein are power plants where electricity is the only
generated product. The performed calculations do not take account of any
other (potential) revenues from the sale of energy origin certificates.
