MODIFIED FUEL GAS TURBO-EXPANDER FOR OXYGEN BLOWN GASIFIERS AND RELATED METHOD

In a power generating plant including a gas turbine (10) which utilizes fuel gas from an oxygen blown gasifier (26) for combustion at a predetermined pressure to drive a primary load, and where the fuel gas (40) is supplied fr om the gasifier at a pressure higher than the predetermined pressure, an...

Beschreibung
Zusammenfassung:	In a power generating plant including a gas turbine (10) which utilizes fuel gas from an oxygen blown gasifier (26) for combustion at a predetermined pressure to drive a primary load, and where the fuel gas (40) is supplied fr om the gasifier at a pressure higher than the predetermined pressure, an arrangement isprovided to decrease the pressure of the fuel gas to a lower pressure required by the gas turbine. This arrangement includes a combustor (42) and an expander (48) downstream of the combustor, the combustor and the expander located between the gasifier and the gas turbine.
