ABSTRACT:
Methods, systems, and apparatuses for exhaust silencers for engines, such as microturbines, are described. An exhaust silencer reduces noise produced by an engine. While passing through an exhaust silencer, an exhaust stream from the engine makes one or more turns, thereby reducing turbine noise. An exhaust silencer includes a body, a cavity in the body, a baffle plate that partially divides the central cavity, an inlet port formed in a first surface of the body, and an outlet port formed in a second surface of the body. The inlet port is configured to receive an exhaust stream that flows through the cavity, around the baffle plate. The outlet port is configured to discharge the exhaust stream from the body.
