摘要： A gas turbine system in which the expanded gas from the turbine section is used to generate the steam in a heat recovery steam generator and to heat a mixture of gaseous hydrocarbon fuel and the steam in a reformer. The reformer converts the hydrocarbon gas to hydrogen and carbon monoxide for combustion in a combustor. A portion of the steam from the heat recovery steam generator is used to cool components, such as the stationary vanes, in the turbine section, thereby superheating the steam. The superheated steam is mixed into the hydrocarbon gas upstream of the reformer, thereby eliminating the need to raise the temperature of the expanded gas discharged from the turbine section in order to achieve effective conversion of the hydrocarbon gas.

摘要： A steam turbine system has a plurality of moisture-separator-reheaters (MSR) each connected via a respective drain line to a corresponding drain receiver. Each drain receiver includes a further drain line coupled through a flow control valve to a common line. The common line empties into a drain cooler connected at the highest pressure end of a series of feedwater reheaters. The drain cooler dumps through another flow control valve to one of the feedwater heaters. Each of the drain receivers includes a pressure sensor and liquid level sensor. A control processor monitors the pressure sensors and selects the drain receiver subjected to the lowest pressure. The processor then fully opens the valve associated with the selected drain receiver and thereafter regulates the liquid level in the others of the drain receivers by adjustment of their respective flow control valves in response to their respective level sensors. The liquid level in the selected drain receiver is adjusted to its preselected level by control of the flow control valve connected to the drain cooler. The pressure in the common drain line is regulated to the pressure at the lowest pressure drain receiver by adjustment of the control valves associated with the other drain receivers.
