Abstract: Embodiments of emission reduction system including various embodiments of an emission filters for a power plant including a gas turbine are disclosed. The system includes: an emission filter; and a retraction system operably coupled to an exhaust passage of the gas turbine. The exhaust passage defines an exhaust path of exhaust from the gas turbine. The retraction system selectively moves the emission filter between a first location within the exhaust path and a second location out of the exhaust path. In a combined cycle power plant, the first location is upstream of a heat recovery steam generator (HRSG). The systems and filters described allow for temporary positioning of emission filter(s) just downstream of a gas turbine exhaust outlet, or upstream of an HRSG, where provided, for emission reduction at low loads or startup conditions, and removal of the emission filter(s) once operations move to higher loads.

Abstract: A system includes a controller including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to receive a first input signal of a first temperature at an inlet of a gas turbine of a gas turbine and heat recovery steam generator (HRSG) system and a second input signal of a rotational speed of the gas turbine. The instructions also cause the controller to calculate the exhaust flow rate of the gas turbine and HRSG system based on the first input signal and the second input signal. Further, the instructions cause the controller to control the gas turbine and HRSG system to isolate a fuel source at a portion of normal operating speed of the gas turbine sufficient to achieve a predetermined purging volume during coast down of air flow through the gas turbine and HRSG system based on the exhaust flow rate.
