| Abstract | ||
| Theoretical exergy analysis is carried out for different components of a combined power plant which consists of a gas turbine unit, waste heat recovery boiler without extra fuel consumption and steam turbine unit. The results pinpoint that more exergy losses occurred in the gas turbine combustion chamber. Its reached 33% of the consumed fuel exergy while the exergy losses in other plant components are between 1% - 5% of the consumed fuel exergy .This paper also considered the effect of the pressure ratio, maximum temperature, boiler pressure and ambient temperature on the exergy losses in the plant, there are a clear effects in the exergy losses when changing pressure ratio, maximum temperature and boiler pressure. | ||
