The performance of two different technological classes of Chemically Recuperated Gas Turbines (CRGT), with methanol used as primary fuel, has been evaluated. The analysis of the influence of the main CRGT parameters on the thermal matching between the flue gas and the reforming fuel in the reformer has been carried out. Emissions in lean premixed and non-premixed combustors have been computed for various reformed methanol fuels of different compositions. This study shows that the CRGT could achieve thermodynamic performance superior to systems with conventional internal recovery and comparable with that of the more complex gas steam combined power plants. Furthermore, the levels of NO{sub x} and N{sub 2}O, produced by the reformed fuels combustion, have been found to be considerably lower than for methane, while the CO emitted is roughly the same as in the case of conventional fuel.
