FIELD: gas mains supplying compressed gas and steam to users. SUBSTANCE: device has distribution unit, gas expansion machine loaded into electric generator, as well as inlet and outlet pressure lines, controller, pressure transducer, and adjustable heat-transfer cooler. Gas distribution unit is made in the form of set of different- diameter tubes mounting shut-off facilities controlled from pressure transducer connected to outlet line through controller. Gas expansion machine is made in the form of constant-speed turboexpander with gas partially supplied to its nozzles. Electric generator is connected in series with variable-speed inverter. Inlets of gas-distribution unit tubes communicate with inlet line and their outlets, with nozzle groups of gas expansion machine whose outlet communicates with outlet line through adjustable heat-transfer cooler. EFFECT: enhanced utilization of gas flow energy resources. 1 cl, 1 dwg
