Abstract: A system includes a bleed system configured to direct a bleed flow from a high pressure region to a low pressure region. The bleed system includes a valve configured to control the bleed flow through the bleed system and a staged bleed conduit configured to incrementally depressurize the bleed flow. The staged bleed conduit includes an inlet coupled to the valve, a first stage configured to depressurize the bleed flow that is coupled to the inlet, a second stage configured to depressurize the bleed flow that is coupled to the first stage, and an outlet coupled to the second stage. The outlet is configured to direct the bleed flow to the low pressure region. The inlet, the first stage, the second stage, and the outlet are disposed along parallel axes.

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.
