Annotatsiya
The article is devoted to the analysis of the possibilities of using excess thermal energy, which is generated during the operation of technological equipment of cable plants during production operations for the release of cabling and wiring products. The equipment used in energy-intensive technological processes for the production of cable products, such as the manufacture of copper wire rod, contact annealing of drawn wire, as well as extrusion associated with the application of insulation and sheathing to cable products, has been chosen as the object of research. The results of the analysis of various methods of disposal of excess heat dissipated by the equipment into the environment are presented. The most rational approach is the conversion of thermal energy into electric energy using heat generators. The possibility of introducing heat generators as an additional unit of cable equipment is being considered, which will effectively utilize the excess heat emission emanating from technological processes. The paper presents the results of laboratory studies performed at the experimental facility. The data obtained characterizing the operation of the facility, as well as the efficiency of energy generation during heat conversion, confirmed the feasibility of the proposed technical solution by increasing energy efficiency by converting excess thermal energy into renewable electric energy.
