Abstract

Abstract. Purpose. The aim of this work is the problem of effective work of system of a heat supply of industrial facilities using recycled and unconventional energy resources. Methodology. To achieve this goal it is proposed to consider some energy-efficient heat supply systems of industrial facilities using recycled and unconventional energy resources: option scheme, in which in each stage the air sequentially passes through first, the unit of the utilization circuit and then to the cooling; use of heat pumps technology in production processes of building materials in rotary furnaces with the utilization of low-temperature gas flows; a combination of complex alternative heat supply system a solar system with an additional source of ground energy heat pump cycle. Findings. During the inspection of heating systems, alternative heating system with solar collectors, heat accumulator, ground heat exchangers in combination with heat pump allows efficient use simultaneously two types of alternative energy for heat supply. With the shortage of alternative energy in the circuit provides a backup source of energy. Originality. Minimization of heat thermo-transformer components in the total energy flux should be dominant in energy saving systems on this basis. Developed heat-technological foundations of devices and systems for energy conservation based on a combination of regenerative and heat pump technology heat recovery with a stabilizing cooling of rotary kilns for industrial and household heating. Practical value. The effectiveness of alternative systems of heat supply is determined by the percentage of substitution of traditional fuels with renewable forms of energy. To increase the proportion of substitution by combined use of two different sources of nonconventional energy, the natural features which is able to reciprocally compensate for the lack of one.
