The use of plant waste to ensure the functioning of agricultural energy complexes

Abstract

RELEVANCE. Agricultural enterprises generate vegetable waste, which is difficult to utilize. Such waste can be used for combustion in boilers, providing thermal and electric energy to an agricultural energy complex. A hybrid mini-thermal power plant combining renewable energy sources and plant biofuels will be able to provide more economical, environmentally friendly and reliable supplies of heat and electricity under any demand conditions compared to using one of these systems.OBJECTIVE. Determination of fuel consumption during combustion of various types of vegetative agricultural waste in a hybrid mini-thermal power plant with parallel connection of solar energy concentrators under conditions of solar insolation of the Republic of Tatarstan.METHODS. The article considers the chemical composition and characteristics of various types of plant waste from agriculture. The average total energy consumption load of an agricultural enterprise has been determined. RESULTS. To determine the consumption of biofuels for the operation of the KE10-14CO boiler, the calculation of the theoretical volumes of combustion products and the thermal calculation of the boiler were carried out. The need for auxiliary fuel at mini-thermal power plants with parallel connection of solar energy concentration plants has been determined. The calculation of the heat collected by the solar collector has been performed.CONCLUSION. The use of solar energy concentrators when connected in parallel with a biofuel boiler makes it possible to evenly supply energy to the enterprise and form biofuel reserves. Calculations have shown that the use of hybrid biomass combustion plants and solar collectors helps to reduce fuel consumption.
