Poplar is the most common type of fast-growing tree species of great economic and industrial importance. Therefore, determining the effectiveness of its energy use is an important task. A study of the operational efficiency of the Firematic 60 boiler when working on poplar chips, as well as pine wood pellets with a diameter of 6 mm and spruce wood pellets with a diameter of 8 mm was carried out. The elemental composition of burned fuels and residues was studied using an EDX-8000 X-ray fluorescence spectrometer and a Euro EA-3000 analyzer. The components of the heat balance and emission of harmful substances were determined. The emissions of particulate matter and the content of soot particles were studied. The shape and composition of soot particles were determined using a Zeiss SIGMA VP electronic scanning microscope. An energy examination showed that the boiler provides high technical and economic indicators and minimal emissions of harmful substances into the environment when burning wood pellets and poplar chips.
