Method of operating a combined cycle electric power plant
This patent describes a method of generating electricity where gas from a high pressure gas transmission line is being delivered to a lower pressure line, such as a gas distribution system. Such a system consists of: supplying a portion of the gas to the combustion chamber of a gas turbine to drive a first electrical generator and produce electricity, using the hot gases in the exhaust of the gas turbine to heat water in a boiler and produce steam and supplying the steam to a steam turbine to drive a second electrical generator and produce electricity. It also reduces the pressure of the gas being delivered to the pressure of the low pressure line and uses the heat of condensation of the exhaust steam from the steam turbine to keep the temperature of the gas at or above a selected minimum as the pressure of the gas is reduced from that of the high pressure line to the pressure of the lower pressure line.
