AI Technical Summary
Existing gas turbine systems face reduced part load efficiency due to the operation of exhaust gas recirculation (EGR) systems, which cool exhaust gases, leading to potential water condensation and icing issues, and the need for additional inlet bleed heat systems for anti-icing, thereby affecting performance and complexity.
Implementing an exhaust gas bleed (EGB) system that bypasses the EGR cooler to mix hot exhaust gases with cooled exhaust gases, controlled by a damper or valve, to maintain or increase intake temperatures and reduce condensation, while maintaining emissions control, thus eliminating the need for inlet bleed heat systems.
Enhances gas turbine performance by preventing condensation and icing, improving part load efficiency, and simplifying the system by eliminating the need for additional anti-icing systems, while maintaining emissions reduction capabilities.
