Experimentally studying TV3-117 gas-turbine unit characteristics at superheated water injection into a compressor

The results from experimentally studying TV3-117 gas-turbine unit (GTU) characteristics at injection of cold and superheated (metastable) water to the inlet of the GTU compressor are presented. In the latter case, the finer water atomization is obtained. The water injection makes it possible to considerably increase the unit power. At a constant temperature of the working fluid downstream of the turbine combustion chamber, water injection in an amount of 1% of the air flow rate provides an increase in the turbine power by approximately 12% and expands GTU controlling potentialities. The use of the metastable superheated water atomization enables one to more reliably implement the technology of water injection into a compressor, especially into intermediate compressor stages. However, it requires accounting for operational conditions of particular installation. Due to small water droplet residence time in the compressor flow path, even with fine water atomization, in aircraft engine derivative power turbines, about 15–20% of moisture injected have no time to completely evaporate within the compressor. When injecting cold water, this figure is from 5 to 10% larger.

Selecting the thermal circuit and profile of a Russian large new-generation power-generating gas turbine unit and a combined-cycle plant built around it

Proposals on the most advisable lines in which the Russian industry can develop advanced new-generation gas-turbine units and combined-cycle plants competitive in the first half of the 21st century are formulated.

World experience with development of combined-cycle and gas turbine technologies and prospects for employing them in the thermal power engineering of Russia using the capacities of the country’s industry producing power machinery and equipment

World experience gained from using combined-cycle and gas-turbine technologies in power engineering is analyzed. The technical and production capacities of the Russian industry constructing power machinery and equipment are analyzed from the viewpoint of its capability of producing up-to-day gas-turbine and combined-cycle units for the country’s thermal power engineering and developing advanced domestically produced new-generation gas-turbine and combined-cycle units.

Turbokon scientific and production implementation company—25 years of activity

The main results of studies performed at ZAO Turbokon NPVP in cooperation with leading Russian scientific organizations during 25 years of its activity in the field of development of unique ecologically clean electric power and heat production technologies are described. They include the development and experimental verification using prototypes and full-scale models of highly efficient air-cooled condensers for steam turbines, a high temperature gas steam turbine for stationary and transport power engineering, a nonfuel technology of electric power production using steam turbine installations with a unit power of 4–20 MW at gas-main pipelines and industrial boiler houses and heat stations. The results of efforts in the field of reducing vibroactivity of power equipment for transport installations are given. Basic directions of further research for increasing the efficiency and ecological safety of home power engineering are discussed.
