FIELD: machine building.
SUBSTANCE: turbine expander plant in gas-distributing station system includes turbine expander, electric generator, high pressure natural gas line, gas-steam heat exchanger and electric steam generator connected to counter-pressure turbine. Gas steam heat exchanger is connected to high pressure line and turbine expander. Electric steam generator is supplied with power from electric generators of turbine expander and counter-pressure turbine.
EFFECT: reaching ecological cleanness owing to absence of fuel burning process, increasing economic effectiveness and eliminating frost and ice formation on working surfaces of turbine expander owing to gas heated with waste turbine steam.
