| Abstract | In 1967, 1st in the world (750 kW) binary power plant was built and successfully tested in Russia on Paratunskiy (Kamchatka) site. Use of ORC technology allows increasing the installed capacity of the existing geothermal power plants (GeoPP) without drilling additional wells due to more efficient use of geothermal fluid. Nowadays JSC "RusHydro" (Russian largest power-generation company) completes the construction of Russian pilot binary power plant 2.5 MW installed capacity, utilizing waste geothermal brine with temperature 120 oC. Heat balance diagram and equipment of this ORC-unit adopted to meet the physical and chemical properties of the organic and geothermal working fluid as well as the severe climatic conditions of Kamchatka region. Installing of such ORC-units on Russian GeoPPs will greatly improve the efficiency of geothermal fluid utilization. For example, the new project of upgrading Mutnovsky GeoPP with ORC units will increase its total capacity on 30%. Currently completed project Feasibility Study allowed identifying engineering proposals providing its high efficiency. |
