GAS-TURBINE PLANT Russian patent published in 2004 - IPC

FIELD: power engineering. SUBSTANCE: invention can be used as stationary plants, particularly as power units in thermoelectric plants. Proposed gas-turbine plant contains gas-turbine unit and recuperative air heater interconnected by gas and air inlet and outlet pipelines with devices for compensation of thermal expansion. Gas-turbine plant has fixed support providing possibility of rigid fastening of air pipelines installed on foundation close to housing of gas-turbine unit. Recuperative air heater is installed for movement in horizontal plane, for instance, on sliding supports. Invention makes it possible to compensate for thermal expansion of main units of plant, reduce power action onto flange connections of compressed air pipelines with housing of gas-turbine unit preventing unsealing, and reduce number of units compensating thermal expansions of air pipelines. EFFECT: improved reliability in operation. 4 cl, 3 dwg
