Abstract
In a power generating plant which utilizes fuel gas for combustion at a predetermined pressure to drive a primary load, and where the fuel gas is supplied at a pressure higher than the predetermined pressure, an improvement is provided wherein a fuel gas expander is located downstream of a source of the fuel gas and upstream of a combustor for decreasing the pressure of the fuel gas, and wherein excess energy from the expander is used to drive a secondary load.
