In today's environment, the demand for low-power electricity sources used to power various devices in the field, such as communication, data transmission, control systems, etc. is growing rapidly. Therefore, it is important to ensure the production of electricity through the use of thermoelectric generators. The paper presents an experimental stand created at the Institute of Renewable Energy, consisting of a burner on which prototypes of a thermoelectric generator are mounted. Unlike the existing prototypes, this work envisages the use of two-phase heat exchange systems (thermosyphons and heat pipes) to intensify heat transfer in the heating system. The heat flow is transferred to the thermoelectric generator by coolant vapours generated in a steam generator located in the combustion chamber area The authors have developed a research methodology and created an automated measurement system that provides measurement of 12 temperature channels, two channels for measuring the electromotive force of thermobatteries and a channel for measuring current and power, equipped with an electronic load for taking volt-ampere characteristics of the thermoelectric generator. Preliminary studies have shown that under the same initial conditions, the developed device provides approximately 4 times higher heat flux and, accordingly, the operating temperature difference on the thermocouples. Further research on the mechanisms of flame stabilisation in the burner is promising, focusing on the addition of secondary air to the combustion
