ABSTRACT:
A fluid discharge silencer for steam or other vapors or gases (with or without entrained solids or liquids) has an expansion chamber into which the fluid is passed through an inlet duct which discharges the fluid over an extended region of the chamber, flow deflector means in the chamber gradually redirecting the flow of gas from the inlet duct to change the direction of flow and to permit the gas phase components of the fluid to expand; the expansion chamber has an outlet which in use is connected to a silencer such as a parallel splitter silencer for further attenuating noise in the discharge flow. The inlet duct can be an elongated pipe having a longitudinal discharge aperture arrangement discharging the fluid into a trough-like redirecting structure which removes entrained components and redirects the flow.
