The North-West of Russia possesses huge wood resources reserves, therefore the issues of the most efficient use of wood biomass are relevant for this region. The implication of wood biofuels into fuel and energy budget provides an opportunity to reduce the negative impact of power industry facilities on the environment and preserve the potential of non-renewable fuels for future generations. An effective way of the complex solution of energy and ecological problems, while providing heating loads for consumers, is the use of modern devices operating on solid biofuel. Technical analysis of foreign and domestic high-performance heating units has great importance. The aim of the research is an evaluation of energy and ecological performance of the Firematic 60 hot water boiler burning bark of linden, briquettes from wood sanding dust and sawdust of plywood processing, as well as briquettes obtained by pressing softwood sawdust and shavings. The paper presents thermotechnical characteristics of burning biofuels and the components of boiler heat balance and gaseous emission from the burning linden bark and briquettes. Particulate matter emission and content of soot were studied. The shape and composition of soot particles were determined with a Zeiss SIGMA VP electronic scanning microscope. Presented data were obtained using equipment of the Research Center of Power Engineering Innovations. The results of the comprehensive energy audit have shown that the Firematic 60 boiler provides high technical and economic performance with minimum emission of harmful substances to the atmosphere. It can be used for low-rise buildings heat supply in weather conditions of the Arctic region especially.
