Abstract

Hydrogen is produced by an externally fired combined cycle and can be consumed in different ways. For the present study, both common and realistic thermodynamic and exergoeconomic analyses were applied. With the realistic method, the results are not necessarily in accordance with common analyses. The compressor pressure ratio (rp) and the gas turbine inlet temperature (TIT) are the varying parameters in common analyses. Varying rp identifies optimum energy and exergy efficiencies. With the common exergy analysis, the gasifier and the heat recovery steam generator have low exergy efficiencies, but the modified analysis assigns high exergy efficiencies to them.
