ÒHÅÌE: "The estimation of pethrogeothermal heat rise opportunity and development of offers upon its use"
The full version in Russian only
The fuel-and-energy complex plays a special role in a national economy of Ukraine, providing functioning of all without exclusion of parts. In connection with limitation of domestic fuel resources, in our country all rises a question on use of other, nonconventional energy sources. One of such sources is heat of the Earths. In comparison with other aspects, such energy is most perspective, widespread and ecologically pure.
One of the simplest ways of rise pethrogeothermal energy is the use of the heat-carrier. For these conditions the elementary device intended for such extraction can serve the «annular tube» type heat exchanger in which outer surface is well casing, and internal, smaller diameter, is go down to in a chink not to the end of a face. If to an annular gap to force the heat-carrier and simultaneously from the central pipe other pump to make its pumping out the heat-carrier, will heat up, contacting with a surface casing which temperature will correspond to temperature of a lying layer of the ground. Having well bottom, the heat-carrier will start to rise on an internal pipe to a surface. The initial geothermal step near to a chink will gradually change. Therefore such system will function only the certain period; there will not come yet the established heat exchange between inflow of heat penetration from bowels of the Earth and selected heat a chink.
For the analysis of an opportunity of rise pethrogeothermal heat in work the adjoint problem is considered. The decision is numerical finite difference methods, and its analysis enables to define efficiency of use of such energy source.
