Abstract
Official abstract text for this publication.
A power plant includes a gas turbine unit adapted to feed flue gases into a diverter where they are divided into a recirculated flow that is fed into a mixer together with fresh air to form a mixture that is fed to a gas turbine unit compressor inlet, and a discharged flow, that is fed into a CO 2 capture unit. A monitoring system for the mixture oxygen content at the compressor inlet is provided. The monitoring system includes a recirculated flow mass flow rate sensor, a recirculated flow oxygen concentration sensor, mixture mass flow rate sensors, a control unit arranged to process information detected by the recirculated flow mass flow rate sensor, recirculated flow oxygen concentration sensor and mixture mass flow rate sensor, to determine an oxygen concentration upstream of the compressor inlet.
