FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to exhaust ducts of gas-turbine drives of gas-transfer plants. Proposed exhaust duct contains exhaust pipe, recovery heat exchanger connected in parallel with exhaust pipe through gas conduit, and rotary gates installed at inlet of exhaust pipe and gas conduit of heat exchanger and connected with drive. Axles of rotary gates are installed in ball supports whose seats are made of thermoexpanded graphite. Axles of gates are connected with ball supports for axial displacement by means of key joint. ^ EFFECT: improved reliability of construction owing to provision of services ability of rotary gates in exhaust duct under action of high temperature gas flow. ^ 2 dwg |
