UTILIZATION TURBO-GAS-EXPANSION MACHINE Russian patent published in 1995 - IPC

FIELD: gas industry. SUBSTANCE: machine has generator 13 and turbine 14. The housing of the generator is made up as a gas pipe plugged from the faces with bottom 16 and cover 13 and separated with a baffle into closed spaces 19-21. The stator and rotor of the generator are mounted inside the generator space. The spaces for discharging and supplying gas to the turbine are provided with branch pipes and interconnected through pipes passing through the generator space to define the piping ring heat exchanger. The branch pipe for discharging gas from the turbine is connected with the pipes of the heat exchanger through the additional space defined by the baffle in the housing with the diaphragm of guide vanes of the turbine. The top and bottom part of the space for discharging gas is connected with the generator space through openings made in the baffle between the generator space and space for discharging gas. EFFECT: enhanced efficiency. 1 dwg
