Abstract: A system includes a bleed system that directs a bleed flow form a high pressure region to a low pressure region. The bleed system includes a bleed conduit that includes an inlet coupled to the high pressure region. The bleed system also includes an outlet that provides the bleed flow into the low pressure region. The bleed conduit it slideably coupled to a housing that defines the low pressure region.

Abstract: A gas turbine exhaust diffuser is configured to be at least partially disposed within an exhaust collector. The diffuser also includes an inner wall configured to extend to a back wall of the exhaust collector, an outer wall circumferentially disposed about the inner wall along a portion of the collector, and an inlet between the upstream end of the inner and outer walls. The inlet is configured to receive an exhaust flow from a gas turbine engine. An outlet for the exhaust is located between the inner wall and a downstream end of the outer wall. The outer wall is asymmetrically shaped so that an opening between the outlet and the back wall of the exhaust collector is larger on a first lateral side of the diffuser adjacent an exhaust exit of the collector than an opposite lateral side of the diffuser.

Abstract: The present application provides an exhaust system to exhaust a flow of combustion gases and a flow of ventilation air from a gas turbine engine. The exhaust system may include an exhaust collector, a transition duct downstream of the exhaust collector, the exhaust collector positioned within an engine room, and a backflow prevention system positioned about the exhaust collector, the engine room, and the exhaust collector so as to prevent a backflow of the combustion gases into the engine room.

Abstract: The present application provides an exhaust system to exhaust combustion gases from a gas turbine engine. The exhaust system may include an exhaust collector and an exhaust stack with a silencer section. The silencer section may include a number of baffles therein. The baffles may include a number of nose cones facing the combustion gases. The nose cones may include a first shape and a second shape.

Abstract: A system includes a gas turbine enclosure. The system also includes a gas turbine engine disposed in the gas turbine enclosure, wherein the gas turbine engine is configured to output an exhaust flow. The system further includes an exhaust driven eductor configured to draw an air flow through and out of the gas turbine engine enclosure using the exhaust flow. The system yet further includes an exhaust stack coupled to the gas turbine enclosure, wherein the exhaust stack is configured to output a mixed flow of the exhaust flow and the air flow. The system still further includes a diffuser plate disposed within the exhaust stack, wherein the diffuser plate is configured to provide a homogenous flow distribution for the mixed flow downstream of the diffuser plate.
