| Summary: | The urgency of the discussed issue is caused by the need to involve local resources of low-grade raw materials in the fuel and energy balance. The main aim of the study is to summarize the results of heat-technology processing of low-grade raw materials, to develop technical solutions for producing solid composite fuel and to determine drying parameters depending on composite fuel sizes and forms. The methods used in the study: Heat-technology processing of low-grade raw materials into solid composite fuel was carried out according to the Patent RF no. 2484125 "The method for producing fuel briquettes from biomass". Thermotechnical characteristics of low-grade raw materials of Tomsk region and composite fuel on its basis were determined in accordance with GOST R 52911-2008 "Solid mineral fuels. Methods for determination of total moisture", 11022-95 "Solid mineral fuels. Methods for determination of ash", 6382-2001 "Solid mineral fuel. Methods for determination of volatile matter yield", 147-95 "Solid mineral fuel. Determination of the highest combustion heat and calculation of the lowest combustion heat". Tests to determine water absorption of the composite fuel were conducted in accordance with GOST 21290-75 "Coal briquettes. Method for determination of water absorption". The mechanical characteristics of the composite fuel were determined according to GOST 21289-75 "Coal briquettes. Methods for determining the mechanical strength". Shape and size of the composite fuel was manufactured according to GOST R 54248-2010 "Peat briquettes and pellets for heating purposes. Specifications" in determining the parameters of drying. The results: The paper introduces the basic principles of heat-technology of obtaining composite fuel from low-grade raw materials and the results of heat-technology processing low-grade raw in Tomsk region into solid composite fuel. The authors have studied the opportunity and parameters of composite fuel waterproofing owing to pyrolysis resin application. Technical implementation of composite fuel production installation according to the heat-technology was proposed and drying parameters for different sizes of cylindrical composite fuel were determined. |
