Abstract

At the moment, the fuel and energy complex of the republic is experiencing crisis state. The main manifestation of the crisis is that disruption and interruptions in the supply of fuel, electricity and heat to individual regions and consumers are becoming commonplace. One of the most promising solutions to this situation is the development of distributed power generation. The process of joint generation of electric and thermal energy 3/4 cogeneration, which, among other things, provides an opportunity for the development of the country’s economy, has great potential here. The purpose of this work is to show the relevance and expediency of using cogeneration at heat sources of the republic. The usual (traditional) method of generating electricity and heat is to generate them separately (power plant and boiler house). At the same time, a significant part of the energy of the primary fuel is not used. It is possible to significantly reduce the total fuel consumption by using cogeneration. Cogeneration is the combined production of heat and electricity from a heat source. Cogeneration is a wide range of technologies that can be applied in various fields of economic activity. The cogeneration plant fits perfectly into the electrical circuit, both for individual consumers and for any number of consumers through state power grids. These units are compact, environmentally friendly and cover the deficit of generating capacity in large cities. Such installations make it possible to unload electrical networks and ensure stable power quality. Cogeneration plants (CHP) are essentially mini-heat power station, which have been successfully used all over the world for a long time.
