Abstract
The article analyzes ways of transforming Ukraine's energy system based on the "Smart Grid" concept with the implementation of distributed generation projects. The expediency of using new tools for the decentralization of thermal and electrical energy sources as a component of small-scale energy, focused on renewable types of uncertified biofuel of local origin, is substantiated. The energy, economic, ecological and social significance of the introduction of systems of thermochemical destruction of bio-waste with the help of jet-vortex generators-utilizers in energy-intensive technologies has been proven. New approaches to the process of heat energy generation in energy-intensive processes of the agro-industrial complex are proposed using the example of grain drying. Thermal engineering means of thermochemical destruction of biowaste, heat exchange system and disposal of combustion products have been developed. A full cycle of production tests of automated jet-vortex generators-utilizers was carried out, taking into account non-deterministic technological parameters (temperature, humidity, productivity, physico-chemical properties of fuel). The cost of thermal energy in technological processes of grain drying is 5...7 times lower than traditional hydrocarbon. Given the presence of a functional heat exchanger, the drying process takes place with heated clean air, which has a positive effect on the quality indicators of the grain. Taking into account the challenges that exist in the electric power industry of Ukraine, a project of a cogeneration plant based on a generator-utilizer and an air turbine is proposed, which, with the help of a heat exchanger and a compressor, converts part of the thermal energy into mechanical energy. With the help of an electric machine converter, electricity is produced, which meets the needs of the heat engineering module of the installation. The total efficiency of the cogeneration plant is about 80 %.
