Abstract

<jats:title>Abstract</jats:title><jats:p>Larch is one of the most valuable species of conifers. Its wood is widely used in many sectors of the economy. Therefore, determining the efficiency of energy use of by-products of processing of larch, as well as fast-growing wood species, which include poplar, is an important task. A study of the operational efficiency of the Firematic 60 boiler when working on larch and poplar chips, as well as spruce wood pellets with a diameter 6 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. The energy tests showed that the boiler provides high technical and economic indicators and minimal emissions of harmful substances into the environment when burning larch and poplar chips, wood pellets.</jats:p>
