Abstract
Systems and methods are provided for controlling the mass flow of an exhaust gas to be delivered from an EGR system to a gas turbine system in a power plant. The mass flow control is provided through a mass flow controller including 1) a primary mass flow control that modulates the mass flow of the EGR flow by adjusting operating conditions of an EGR blower, 2) a secondary mass flow control that maintain power optimized operation of the EGR blower by adjusting the position of an EGR outlet damper, and 3) a tertiary flow modulation control that limits the EGR operation within mechanical design boundaries of the EGR duct by throttling the position of an EGR inlet damper. As such, the presently disclosed embodiments may operate independently to provide precise mass flow control within the EGR system, optimize power consumption of the blower, and safeguard the EGR system within its design boundaries.
