Title:
Gas-constituents control in the gas-turbine-power-generation device using stack gas re-circulation
Document Type and Number:
Japanese Patent JP5905119
Kind Code:
B2
Abstract:
The invention relates to a method for operating a gas turbine power plant with exhaust gas recirculation. In the method a setpoint concentration of one component of the inlet gas and/or of the hot working gas and/or of the exhaust gas of the gas turbine is determined in a first step, in accordance with the operating conditions of the gas turbine, from a combination of a setpoint value of a control loop, a feedforward control signal and a correction value. In a second step, the position of a control element is adjusted in accordance with the setpoint/actual deviation in the concentration of the component. The invention furthermore relates to a gas turbine power plant for carrying out the method.
