Natural gas is transported to users at pressure of 7.5-5.6 MPa and is distributed within residential areas at pressure of 1.2 MPa. However, the pressure required at consumers (thermoelectric and hydroelectric power stations) is 0.2-0.4 MPa or less. The surplus potential energy, which is lost at throttling devices of gas expansion stations and gas regulating rooms, can be used for generation of additional electric power and for process purposes. For example, the gas consumed by a 800 MW steam turbine set with a pressure differential of 1.1 -0.17 MPa can give additional power of over 11 MW. Long-standing experience in design and manufacture of gas recovery turbines allowed us to create ТГУ-11 turbine. The gas recovery turbine type ТГУ-11 represents a multistage expansion turbine, which generates electric power using excess pressure of the natural gas supplied as fuel to boilers of thermal power stations (TPSs).

The gas Top Pressure Recovery Turbine (TPRT) is designed to drive electric generators. The turbine is run by excess pressure of the blast-furnace gas at metallurgical plants. Up to 40% energy spent for blasting is recovered with almost no fuel consumed. It easily fits the process cycle of either newly commissioned or existing blast-furnace equipment. The actual power developed by the turbine depends on the operating regime of the blast furnace and is determined by the flow rate and pressure of the gas passing through the turbine. Correspondingly, the TPRT turbine is available in several modifications: TPRT -12М, TPRT -8М and TPRT -6М. The turbine is an axial double-stage direct-flow unit. It can be supplied with or without a gas heater.
