Abstract

Principal possibility of heat-pumping technologies application for heat recovery of the traditionally lost low-grade heat on the thermal electric stations with the purpose of efficiency increase of the primary fuel use is considered. On the example of municipal heat-electric generating plant work during a year analysis waste heat potential suitable for the use in heat-pumps as low-grade heat is appraised. Characteristics of heat-pumps that are present in the world market and suitable for thermal power-stations waste heat utilization are considered. The credible consumers of producible heat-pumping installations heat on thermal power-stations and the simplest basic schemes are analyzed. The brought results show technical feasibility and perspective of heat-pumping direction of the thermal electric stations low-grade heat utilization and necessity of further researches realization for the ground of his technical and economic expediency.
