“…Due to the nature of processing, the SCF has a higher ash content and less volatile substances than the initial LR, but its lowest calorific value is 2.1-6.8 times higher [6]. Moreover, the fuel has mechanical strength, according to GOST R 54248-2010, sufficient for use in the housing and utilities sector: 100% resistance to fracture when dropped, and a compression resistance of over 0.3 MPa (test method GOST 21289-75).…”

Abstract. An evaluation is made of the thermal energy consumed in the heat-technology production of solid composite fuel from low-grade organic raw materials. It is shown that the heat of decomposition of the organic mass and the combustion of the by-products of heattechnology may be sufficient to cover all the energy needs for processing peat, brown coal and wood chips. Producing solid composite fuel from sapropel requires external resources to compensate for part of the heat consumed. Calculations show that it is possible for the thermal processing of raw materials to proceed autothermally due to the heat of decomposition when the moisture content at the reactor inlet is limited: for peat it should be no more than 35%, 54% for brown coal, and 37% for wood chips. The low heat of decomposition of the sapropel organic mass means that its thermal processing cannot proceed autothermally.

Abstract. Involving of local low-grade fuels resources in fuel and energy balance is actual question of research in the present. In this paper the possibility of processing low-grade fuel in the solid fuel composite was considered. The aim of the work is to define the optimal parameters for formation of the solid composite fuel. A result of researches determined that dextrin content in the binder allows to obtain solid composite fuel having the highest strength. The drying temperature for the various fuels

“…Necessary to consider that the creation of power stations based on high temperature gas generators for small settlements is not expedient, because it pretty complicated technical device, specified in maintenance and required a certain qualification from personnel. The production and consumption of fuel briquettes is perspective direction in view of modern developments in the field of briquette production from low grade fuels [14,15]. The briquette fuel can be combust in exist furnace units with grate firing without their reconstruction.…”
