Abstract:
Modern technologies for the exploitation of geothermal energy in power plants or heating systems have been developed in Russia since the late 60's [1]. In 1967, the first binary cycle geothermal power plant in the world was built in Russia, at Paratunsky . This plant used hot water at 90о C for electricity generation. In 1999 the 12 MW Verkhne-Mutnovsky geothermal power plant (V-M GeoPP) in Kamchatka was put into operation. The Mutnovsky GeoPP (50 MW) was commissioned in October 2002 and has been in successful operation despite of severe climate conditions. Currently a new generation of geothermal binary power plants is being developed in Russia. This new technology is aimed at the production in series of smaller systems for the conversion of low-enthalpy heat sources into electricity and/or heating. JSC “RusHydro Engineering Center of Renewable Energy” with the scientific and technical assistance of SC “Geotherm-EM” have designed and are building a pilot plant at the Pauzhetsky site [2, 3]. Research and development activities include system design, fluid selection, experimental investigation of several aspects, components selection and development of the control system.. The Pauzhetsky installation will include: the turbo-unit and its auxiliaries, condenser, heat exchangers (heater, evaporator and super-heater share a common housing), feed pumps, auxiliaries of the power unit (including storage tank for waste working fluid), corrosion-protection and salt-sedimentation-protection devices, and cooling water pumps. The project is at the stage of pre-commissioning. Various aspects of the design, construction and commissioning are discussed. REFERENCES [1] G. Tomarov, A. Nikolsky, V. Semenov, A.
