Abstract
A gas turbine engine including an exhaust bleed (ExB) system and methods of operating the same to achieve increased turndown while maintaining emissions under a compliance limit. The method includes continuously decreasing a load of the gas turbine engine below a base load, and, as the load is continually decreased, continuously determining a reference load. When the reference load reaches a first threshold value, the method includes operating an inlet bleed heat (IBH) system of the gas turbine engine according to a first schedule. When the reference load reaches a second threshold value, the method includes operating the IBH system according to a second schedule. When the reference load reaches a third threshold value, the method includes operating the ExB system according to a third schedule. When the reference load reaches a fourth threshold value, the method includes adjusting an exhaust gas temperature setpoint of the gas turbine engine.
