Power plant for the battery farm at Konstantinovo settlement.

The article is devoted to the power project realized on the base of gas engine power plant at the battery farm in Moscow Region.

Captive power plant projects always involve a great deal of difficulties. One of them is providing interoperation between home and foreign equipment. Another one is the collecting initial permissive documentation for the project.

ABB Turbo Systems in Russia: a new service centre in Vladivostok.

The second in Russia ABB service centre provides wide opportunities for qualified up-to-date turbocharger maintenance for the supply of the new equipment in the Far East. Regular training of engineers in Switzerland provides high-quality services. ABB plans to extend its activity by widening service network close to the customer providing twenty-four-hour technical support and the supply of original parts.

Gas turbine power units are run at Vladivostokskaya TETs-1, CHP plant.

Mobile GTPP JSC commissioned two Mobilepac gas turbine power units rated at 22.5 MW to eliminate the deficiency of electric power supply in Vladivostok. By the time of being the total number of Pratt & Whitney power units run on the territory of Russia has come to 14, Mobile GTPP JSC being the general contractor for the projects.

Mobile GTPP JSC was established in 2006 as a subsidiary of RAO UES of Russia. The aim was to prevent the occurrence of emergency situations in the areas of Moscow power grid in short supply. The first company’s project was installation of mobile gas turbine power units in Moscow region to support the power system at peak loads.

The application of absorption chellers in trigeneration power systems.

Thermal power sources such as waste hot water and exhaust steam can significantly decrease the cost of cooling systems for up-to-date climate control and industrial installations.

Over 40 years Japanese SANYO corporation is engaged in engineering and production of high-quality absorption systems on the base of severe scientific and technological developments.

SANYO offers a wide range of absorption chillers perfectly suited for trigeneration systems application. At present the application of trigeneration systems is the most effective way to decrease energy consumption cost.

The influence of hot gas path surface quality on the performance of turbine stages.

Quality weakness of blade rings surfaces significantly decreases the efficiency of turbine stages as a result of additional aerodynamic loses.

The application of protective coatings and welding depositions for blades will be the most effective under the conditions of permissible cleanliness level of blade surfaces and minor thermal deformation of blade packets.

On-time maintenance to control the cleanliness level of the blade system allows to increase significantly blade efficiency, reliability and service life and to improve environmental parameters.

Eagle Burgmann mechanical seals with diamond coating.

Burgmann Industries GmbH. & Co. KG (Wolfratshausen, Germany) has developed and introduced absolutely new diamond coating for seal faces. The (microcrystalline) coating provides high wear resistance during short-term total or partial dry run and in multiphase media.

Experiences with Wood Particles as Regenerative Fuel for Directly Fired Gas Turbines of the Small Power Range.

The utilization of regenerative solid fuels like wood for the simultaneous production of heat and electricity is done nowadays mostly by the means of steam power plants. The directly fired gas turbine plant with relatively low capital costs can be considered as alternative to heat-and-power stations on the basis of steam processes. A reduction of capital costs and an increase of plant reliability are supposed to be achieved by the usage of widely used and well-proven components.

Since a full burn-out of solid fuels takes more time than that of gaseous or liquid fuels, a pressurized combustion chamber capable for the combustion of wood fuels has to be developed.  Beside of the concept of the directly wood particle fired gas turbine, experimental results of the gas turbine plant of the Institute are presented. To achieve a technically complete burn-out of wood fuels and to avoid a formation of nitrogen oxides the combustion of wood fuels is done by a two-stage concept.
