The development of ejector technology is analysed as it applies for solving environmental problems. Success achieved in this field is connected with its special features the full absence of rotating and movable parts, lubricants and any seals and, consequently, the high reliability and low capital costs. This article concerns the use of jet devices for utilisation of steam obtained by means of renewable energy sources (solar and geothermal) and of waste steam after the various industrial processes, for such purposes as hot water and heat supply, water lifting and desalination. Jet devices are used in these cases as the pumps, heat exchangers and condensers. It is expedient to use jet devices in chemical technology (for example, for water purification), for compressing and transportation of gases and in low toxic vehicles. The article contains a description of these industrial applications, their schematic diagrams and the results of investigations and tests of jet devices in laboratory and field conditions.

Keywords: environmental protection, ejector technology and devices, waste heat, solar and geothermal plants, steam-water mixture, condensing injector, pumping, water lifting, heat supply, desalination, water purification, energy saving, hydro-compressor, steam and gas ejector unit, hydrogen, liquefied natural gas, low-toxic vehicles
