Patent number: 11815018Abstract: A box-shaped air intake silencer with vertical baffles for a gas turbine system. The box-shaped silencer has a silencer housing having opposing ends with a first end closed and a second end opened to permit passage of air. Opposing sidewalls extend between the first end and the second end with each of the sidewalls operative to receive a perpendicular flow of intake air. A silencer having vertically, spaced baffles are disposed within the housing. A first end of the baffles face the first end of the housing and a second end of the baffles faces the second end of the housing. Each of the baffles extend horizontally between the first end and the second end of the housing. The baffles receive the perpendicular flow of intake air proximate the first end of the housing and direct the intake air towards the second end of the housing for passage therethrough.Type: GrantFiled: December 15, 2021Date of Patent: November 14, 2023Assignee: GENERAL ELECTRIC COMPANYInventors: Ravinder Yerram, Quoc Hoai Nguyen, Balakrishnan Ponnuraj
