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 %.
基于涡流发电机组的分布式热电联产的发展
文章分析了以“智能电网”为理念,通过实施分布式发电项目改造乌克兰能源系统的途径。利用新的工具分散热能和电能作为小规模能源的组成部分,集中于可再生类型的当地来源的未经核证的生物燃料,是一种权宜之计。在能源密集型技术中,利用射流涡发生器-利用器对生物废弃物进行热化学破坏的系统在能源、经济、生态和社会方面的意义已经得到证实。以粮食干燥为例,提出了在农工综合体高耗能过程中热能产生过程的新途径。开发了生物废弃物的热化学破坏、热交换系统和燃烧产物处理的热工程手段。考虑到不确定的技术参数(温度、湿度、生产率、燃料的物理化学性质),对自动化喷气涡发生器-利用器进行了全周期的生产试验。粮食干燥工艺过程中的热能成本为5…比传统碳氢化合物低7倍。由于存在功能热交换器,干燥过程在加热的清洁空气中进行,这对谷物的质量指标有积极的影响。考虑到乌克兰电力行业存在的挑战,提出了一种基于发电机-利用器和空气涡轮机的热电联产电厂项目,该项目借助热交换器和压缩机将部分热能转化为机械能。在电机变换器的帮助下,产生电能,满足安装热工模块的需要。热电联产装置的总效率约为80%。
