THE USING ENERGY FOR HEAT AND POWER SUPPLYS

Abstract

In given paper the present day state of geothermal power engineering of Daghestan and prospects of its further development are considered. Grounds of unsatisfactory use of geothermal recourses in national economy are analyzed.

To improve the profitability of geothermal production, numbers of prospective technologies are suggested, that kind as the heat-pumping systems of heat supply with attraction of low-potential thermal waters, combined-separate extraction of fiesh low-potential and salt middle-potential waters fiom the same well and combined production of electrical energy and heat with inclusion of heat pump cycle m bicontour system.

Republic of Daghestan is the most prospective region of Russia for geothermal power development. Resources for geothermal power engineering are rather great. In sedimentary section of Daghestan foothills and plain three structural hydrogeothermal stages are dsistinguished represented by series of thick regional aquifers, where enormous resources of low-potential (30-60oC) middle potential (60- 120oC) and high potential (120oC) thermal waters were explored.
