Samenvatting:
Modern gas turbines extensively employ air cooling to reach high turbineinlet temperatures. However, cooling causes losses in the gas turbine cycle.
The use of carbon-fibre reinforced carbon composites in turbine blades allows
operation at very high temperatures without the cooling losses. The
sensitivity of the carbon composites to the presence of oxygen requires a
fuel-rich atmosphere, which is created in the first stage of the Chemical Gas
Turbine. This paper deals with the thermodynamics of a combined-cycle plant
based on the Chemical Gas Turbine. The cycle was evaluated and optimized, and
a basic exergy analysis was carried out. The results showed a high efficiency
of the proposed cycle and indicated ways for further improvement. 7 refs.
