Title:
CONTROL OF GAS COMPOSITION IN GAS TURBINE POWER PLANT WITH FLUE GAS RECIRCULATION
Document Type and Number:
Japanese Patent JP2012154330
Kind Code:
A
Abstract:

To provide a method for operating a gas turbine power plant with flue gas recirculation.

In the method, target concentration of at least one constituent in a flue gas flow and/or in an intake flow of the gas turbine 6 after mixing of the recirculated flue gas is determined in response to the operating state of the gas turbine. Furthermore, actual concentration of at least one constituent in the flue gas flow and/or in the intake flow is measured, and a control element for controlling the recirculation flow is controlled in response to a deviation between the target concentration and the actual concentration. Also provided is a gas turbine power plant with exhaust gas recirculation. For executing the method, a control device has measuring devices 36, 37, 38 for measuring the actual concentration of at least one constituent. The target concentration of at least one constituent in the flue gas flow or in the intake flow of the gas turbine 6 is calculated through the control device.
