IMPROVED POWER PLANT

An integrated gasifer combined cycle power plant comprises a gasifer (10) and at least one gas turbine (20) downstream in the syngas stream from the gasifer (12) and driven by the syngas stream therefrom. A burner (30) superheats steam produced by the cooling of the fuel gas stream between the gasif...

Zusammenfassung:	An integrated gasifer combined cycle power plant comprises a gasifer (10) and at least one gas turbine (20) downstream in the syngas stream from the gasifer (12) and driven by the syngas stream therefrom. A burner (30) superheats steam produced by the cooling of the fuel gas stream between the gasifer outlet and the gas turbine (20), by combusting hydrogen and oxygen in the steam to heat it. At least one secondary turbine (32) downstream of the burner (30) is driven by the superheated steam therefrom. This allows energy to be recovered very efficiently, improving the overall thermal efficiency of the plant whilst requiring much simplified steam pipework in comparison to conventional systems.
