This article discusses the waste heat utilization technology of various industries, by steam-turbine installations working by an organic Rankin cycle. Application of this technology allows making the electric power without any fuel expenses which allows to decrease the relative emission of production pollution, to decrease the environmental heat pollution and to increase the efficiency of fuel usage in the main production. As an example, the study presents a calculation of the potential of waste heat utilization for the PAO «Gazprom» gas transmission network, which amounts to 3,9 GW, allowing to reduce the relative emission of production pollution by 25 %. The article also offers information about the 560 kW organic turbine design and the problems of experimental research.
