  "textContent": "A sound attenuating duct unit (40) suitable for connection to an outlet of a gas turbine (10) and an improved heat recovery apparatus for use with such a turbine are disclosed. The former unit includes a duct housing (42) having exterior sides, an air inlet (46) at one end and first and second air outlets (80, 64). Interior walls define a main airflow passageway extending from the air inlet to both of the outlets. Sound absorbing material (101) is arranged between these walls and the exterior sides. Sound attenuating members (120) are mounted in the passageway and a diverter damper (96) is mounted in the housing and is able to direct air flow to either one of the air outlets. The sound attenuating members (120) are mounted between the diverter damper and the air inlet (46). The heat recovery apparatus includes a series of aerodynamic diffusers (175, 200) mounted in a housing adjacent an air flow inlet connectable to the gas turbine (10).",
