Abstract:
Purpose. Comparison of the efficiency of uncertified fuel use in a bioenergy complex of a new type and traditional thermal energy generation systems.
Methodology. The research is based on mathematical modeling of the bioenergy complex. Indicators of efficiency of application of continuous solid-fuel heat generators for drying process were studied using experimental and analytical methods.
Findings. It has been established that for efficient burning of solid fuel, it is necessary to ensure coordinated control of individual modules comprising the electrotechnological complex of the solid-fuel heat generator, in particular, to solve the problem of controlling the rotation frequency of the fan and the dosing screw feeder electric drives, determining the volumes of dosing the combustion components. The principal task of ensuring energy efficiency of the solid-fuel heat generator by identifying regulated biofuel dosage regimes, based on the analysis of oxygen percentage in flue gases, has been solved.
Originality. The efficiency of combustion components rational dosing ensured by implementing regulated modes of a dosing screw feeder and fan operation has been substantiated by the analysis of flue gases composition, which made it possible to increase the energy efficiency of solid-fuel heat generators.
Practical value. The regularities of biofuel components rational dosage are determined in terms of flue gases composition and the physical and chemical properties of the processes in the fuel mixture. The economic expediency and efficiency of drying various materials are considered in the context of biodegradable energy generation systems.
