“…Technical and energy characteristics of three composite fuels have been determined experimentally [9][10]. Samples of 3B grade coal (Balakhtinskoe deposit, particle size less than 80 microns), fine sawdust and flour industry waste (particle size less than 200 microns) were mixed in different volume concentrations in a galvanized drum of Pulverisette 6 planetary mill with spherical grinding bodies with 5 mm diameter at required volume ratios.…”

Abstract. Experimental studies have been carried out to determine the energy and technical characteristics of composite fuels from coal grade 3B (Balakhtinskoye deposit), fine waste and flour from the milling industry. An effective concentration of 50% / 50% composite fuel has been established without the addition of a flour component, in which the combustion heat is reduced by less than 8%, with the flour component added up to 15%, the heat of combustion further decreases less than 2% of the heat of combustion of homogeneous coal. At the same time, the ash content is reduced to 11%, the yield of volatile components remains at the concentration level of the composite fuel of coal and wood. It is established that this component composition of three types of fuel is suitable for the formation of fuel briquettes suitable for burning in furnaces of small power boilers.

“…High wear of public infrastructure is a current problem for many regions in Russia [5]. The work on heat networks and boiler systems modernization does not only allow to prevent areal communal fail but also leads to the increase of energy efficiency -old equipment is replaced with the new one with improved performance [6][7].…”

Abstract. The article deals with the modernization process of automated control system of operating process of boiler unit at South Kuzbas hydro electric power station. The boiler unit has been modernized through the installation of automated control system and control on hierarchical arrangement consisting of the levels where the tasks of input and ouput control signals are distributed. Controllers produced by Ram Company and sensors produced by Elemer company were used for modernization of boiler unit. Automatic and process control was made on the base of MicroSCADA software. It has been currently estimated that the use of automation system will result in decrease in fuel consumption by 1 % and reduce nitrogen oxide and carbon monoxide emission by 3 %. System payback time would be no more than two years.

“…While energy consumption is expected to increase by 35 % to 2035 year the share of coal generation is expected to be significant and has a value close to 25 % [1]. Such decrease is seem to appear due to economic and ecological issues connected to coal usage like carbon, sulfur and nitrogen oxide emissions, lower efficiency compared to combined cycle for natural gas and solid particles in flue gases [2].…”

Abstract. Phycial-mathmatical model for fixed-bed coal gasification process simulation is proposed. The heterogeneous carbon oxidation chemical reactions were simulated via Arrhenius equation while homogeneous reactions in gas phase were calculated using Gibbs free energy minimization procedure. The syngas component concentration field and fuel conversion distribution as well as syngas final temperature and composition were defined for fixed bed gasification of T-grade coal of Kuznetskiy deposit. The optimal fuel residence time and gasifyer specific productivity were defined. The prevail reactions in oxidizing and reduction zones together with its height were defined.
