Abstract:
The present application provides a gas turbine system. The gas turbine system may include a gas turbine engine producing a flow of exhaust gases, a heat recovery steam generator with a reheater and an evaporator in communication with the flow of exhaust gases, and a gas flow control system for diverting a first portion of the flow of exhaust gases away from the reheater and towards the evaporator.
Abstract:
The present application provides a cooling system for a gas turbine. The cooling system may include a source of CO2, a stator blade cooling system positioned about a casing of the gas turbine and in communication with the source of CO2 and a number of stator blades, and a rotor blade cooling system positioned about a rotor shaft of the gas turbine and in communication with the source of CO2 and a number of rotor blades. A first portion of a flow of CO2 may flow through the stator blade cooling system and returns to the source of CO2 in a first closed loop and a second portion of the flow of CO2 may flow through the rotor blade cooling system and returns to the source of CO2 in a second closed loop.

Abstract:
A method for determining an operating set point for a combined cycle power plant, the method includes: simulating the operation of the power plant; correcting the simulation of the operation of the power plant; optimizing the simulation of the operation by simulating the operation at different operating settings and selecting at least one of the operating settings as being optimal, and generating the operating set point based on the optimized simulation of the power plant.
Abstract:
A method and system for capturing and isolating carbon dioxide and hydrogen gases from a high temperature synthesis gas stream containing a substantial amount of CO and sulfur compounds for use as a “clean” supplemental fuel, comprising the steps of reducing the temperature of the high temperature synthesis gas stream, removing substantially all of the sulfur compounds present in the synthesis gas, converting a first portion of CO to carbon dioxide in a first high temperature water-gas shift reaction, converting a second portion of CO to carbon dioxide using a second low temperature water-gas shift reaction, converting a third portion of CO to carbon dioxide using a third low temperature water-gas shift reaction and then separating out substantially all hydrogen present in the treated synthesis gas stream.
