Development and testing of thermoelectric conversion device

Abstract

The purpose of the work is to create an energy-saving device converting thermal energy into electrical energy. A review of technical solutions in the field under study showed the possibility of using thermoelectric conversion modules for electric energy generation for production needs. In the frameworks of the study, a laboratory installation was created and investigation tests of thermoelectric conversion modules were carried out. Experiments were conducted at different temperature gradients of heat-transmitting surfaces. A design of the thermo-electric converter unit consisting of 12 modules, a cooling radiator and a switching unit was developed. Pilot tests of the thermoelectric conversion unit have been conducted in the system of gas treatment facilities of the aluminum plant. The results obtained confirm that the device can provide sufficient power generation for artificial lighting of an industrial site. The authors propose a layout option of thermoelectric conversion units for the installation of gas ducts intended for hot gas or liquid transportation. The number of modules in the unit, their type and method of electrical connection can vary depending on the requirements of output energy parameters, gas duct overall dimensions, as well as operation and installation conditions. The research results can find application in energy, oil and gas, metallurgical and chemical industries.
