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: Thermal energy storage is leveraged to store thermal energy extracted from a bottom cycle heat engine. The thermal energy stored in the thermal energy storage is used to supplement power generation by the bottom cycle heat engine. In one embodiment, a thermal storage unit storing a thermal storage working medium is configured to discharge thermal energy into the working fluid of the bottom cycle heat engine to supplement power generation. In one embodiment, the thermal storage unit includes a cold tank containing the thermal storage working medium in a cold state and a hot tank containing the working medium in a heated state. At least one heat exchanger in flow communication with the bottom cycle heat engine and the thermal storage unit facilitates a direct heat transfer of thermal energy between the thermal storage working medium and the working fluid used in the bottom cycle heat engine.
