The process of transformation of energy of thermal emissions of a biocotlet into electric energy. The aim of the investigation. Improving the energy efficiency of the heat generators that work with help of the alternative fuels by implementing the thermoelectric elements in the mode of generating electricity into the power cogeneration plant. Methods of the investigation and equipment. Theoretical studies were based on the theory of thermoelectric transformation, the laws of thermodynamics, the theory of heat transfer, and were accompanied by the development of a mathematical model, which was performed using the theory of identification, the theory of experiment and computer simulation. Mathematical models of thermal processes in the heat generator and thermocouples, taking into account the influence of external factors, are developed using the theory of thermal processes. To create computer models, the theory of simulation was used and the Matlab / Simulink software environment was used; Graphical presentation of simulation results was performed by means of MS EXCEL and Matlab environment.Theoretical and practical results. The possibility of obtaining electric power of 5-13 W from one thermoelement in working temperature modes is proved, depending on the chosen modification of TEG. It is substantiated that the maximum value of the efficiency of the thermoelectric module is achieved by providing the maximum permissible temperature difference of 100-120 ° C on its surfaces and the value of the electrical resistance of the load approximating the internal resistance of the generator module 2.5-5.5 Ом. The algorithm of selection of maximum power of TEG has been developed, which allows to provide the maximum power output of 200 W and efficiency - 7%, by calculating the required output current of the thermomodule and maintaining the minimum possible average temperature on its surfaces.Scientific novelty. A fundamentally new method of increasing the energy efficiency of an autonomous cogeneration system based on a solid biotep-generator with the use of an electrenergizing module is proposed, which makes it possible to use the energy of thermal emissions of the heat generator with maximum efficiency. The interconnection of the generated electric power of TEG with the heat of flue gas is established, taking into account the dependencies of the calorific value of solid biofuels on the type of wood and its moisture content. For the first time, the energy-efficient operating temperature ranges of the thermoelectric converter and the resistance of the consumer have been determined, which provide its maximum output power, taking into account the average temperature of the module and load resistance.The effeciency of introduction. The proposed method for increasing the energy efficiency of an autonomous cogeneration system based on a solid biotep-generator with the use of an electric generator module was tested at the production facilities of LLC "Ukrainian Technological Systems" in the Ternopil region. and NGO "Energy-saving technologies" in Ternopil. The obtained results proved the possibility of increasing the energy efficiency of an autonomous cogeneration unit by 3.5-4%. The calculated annual economic effect of the implementation is 3628 UAH, payback period is 34 months. Product Description popup.authors Іскерський І.С. Брездень Т.І. Бурега Н.В. Загородній Р.І.
