Abstract: An exhaust control damper system for a power plant includes a frame configured to be fluidly coupled in an exhaust flow path from a gas turbine (GT) system to a heat recovery system. The damper system includes at least two sets of louvered dampers in the frame and collectively covering the exhaust flow path. Each set of louvered dampers includes a plurality of blades collectively angularly positionable in one of: a fully open position, a fully closed position, and a partially open position. An air insertion system is coupled to the frame and configured to insert an airflow into the exhaust flow path to control the exhaust temperature entering the heat recovery system. The sets of louvered dampers can be modulated independently to control exhaust flow distribution and mass flow to the heat recovery system.

Abstract: A gas turbine engine system includes a fuel delivery circuit configured to convey fuel, a combustion chamber configured to combust the fuel, and a flexible hose that fluidly connects the fuel delivery circuit to the combustion chamber. The flexible hose includes a combustion chamber connector portion attached to the combustion chamber, a fuel delivery circuit connector portion attached to the fuel delivery circuit, and a central flexible portion connecting the first connector portion to the second connector portion. The central flexible portion is made of a flexible material. In addition, the fuel delivery circuit connector portion includes a pivotal assembly with an adjustable end that is pivotal relative to a central longitudinal axis of the central flexible portion of the flexible hose when the central flexible portion is in a straight condition.
