The ability for using of fuel gas power potential is reviewed in two-stage scheme of his pressure decrease. The first stage is in the Gas Distributing Station (GDS) and the second is in Gas Regulating Unit of the rotary kilns. The main working characteristics are received for turboexpander units in the second stage when they work on the variable rotation frequencies with ability of drive the blower units. It is shown using of fuel gas power potential in second stage of his pressure decrease brings weighty power growth. It is established that it is impossible to refuse using the throttle regulator valve before the turboexpander unit in the first stage of gas pressure reduce in GDS for change the pressure in the intermediate gas pipeline.
the stages of decrease the gas flow pressure, the utilization turboexpander unit, the throttle regulator valve, the variable work mode, the difference of pressures, the fuel gas, the rotation frequency, the balance of capacities
