The project aims to develop an energy saving method for conversion of thermal to electric energy. The review of engineering solutions in this area demonstrated the rationale for using thermoelectric generator (TEG) modules to produce energy for business use. As a part of the research, ANSYS models were developed and thermal fields of flue walls were studied at different flow speed rates and gas air environment temperatures. A design of the TEG unit consisting of 12 TEG modules, a cooling radiator and a switching unit was developed. A bench for studying the efficiency of converting thermal to electric energy was designed. Experiments using three types of TEG modules were carried out. Capacity values at different temperature gradients were determined. Pilot testing of a high performance thermo-electric generator was carried out within the temperature range under study. It was identified that by increasing the number of TEG units, it is possible to meet technological needs. A system consisting of single inline TEG units was developed. It was used for making circular cross sections in flues. The number of TEG units, the type of modules and the method for their connecting depend on capacity rates, temperature and flue dimensions. The authors filed a patent application. The possibility of research results commercialization in the oil and gas, metallurgy and chemical industries is being explored.
