In wartime conditions, the issue of providing low-power power sources for communications and various military equipment in the field has become extremely urgent. Such sources should provide the possibility of uninterrupted power supply, have a small mass and dimensions, and not require special types of fuel. This demand is met, in particular, by developing thermoelectric generators that run on organic fuel. Such generators are designed for short-term use and do not have a heating function. More powerful generators have a large mass and dimensions, which is why they cannot be considered for autonomous and mobile applications. This paper presents a compact thermoelectric device for power generation using combustion. The device was developed with an emphasis on low cost and a realistic stand-alone design with potential for commercialization. The expected technical characteristics of this generator provide it with competitiveness compared to existing models, which, in view of the growing demand for such equipment, opens up opportunities for the export of these devices to European countries. Previous research has shown that catalytic combustion is one way to improve flame stabilization, but using a catalyst in the system increases production costs, which can be a significant drawback. Further research into the mechanisms of flame stabilization in the burner, in which the main attention is paid to the addition of secondary air to the combustion chamber, is promising. These studies can be divided into two stages. The first stage of research involves the development of the burner, which consists in optimizing the design to achieve a stable closed flame of the premixed mixture according to the design and operational requirements. The second stage of research should focus on the integration of the burner with thermoelectric energy generators, in particular on the study of different configurations to optimize the electrical power output in the presence of a limited amount of heat.
