Turbo-generator exhaust noise silencer

Image Number 7 for United States Patent #6161646.

A silencer for reducing acoustic energy in an exhaust stream of gases from a combustion type source, particularly turbo-generators. In a preferred embodiment, the silencer includes an outer housing having at least one outlet opening and an inner housing provided at least partially within the outer housing. The inner housing has at least one inlet opening for receiving the exhaust stream along a flow axis and the inlet opening is in fluid communication with the outlet opening. The inner housing further includes an acoustic energy interface surface having acoustic absorbing elements oriented in a substantially non-normal direction to the flow axis. Sound absorbing material is preferably contained between the outer housing and the inner housing. In this way, the gas flow is effectively separated from the acoustic energy without significantly increasing the back pressure or resistance to flow of the exhaust stream.
