Increase of energy efficiency of energy generation due to utilization of waste heat on district heating systems

[摘要] The relevance of the work is due to the implementation of the Federal law "on energy saving and energy efficiency and on amendments to certain legislative acts of the Russian Federation" and is aimed at reducing the cost of production of electric and heat energy in the Northern regions of decentralized energy of Russia. The aim of the work is iimproving the energy efficiency of thermal energy production through the modernization of coal-fired boilers, the rationale for the choice of an alternative technology to convert thermal energy into electricity in the areas of decentralized energy. Creation of the installations competing with diesel power plants on development of thermal and electric energy, increase of economic efficiency of production of energy in Northern regions of Russia. Research methods is analysis of existing technologies for the production of thermal energy in the areas of decentralized energy; Thermal, technical and economic analysis of technologies that allow to convert low potential thermal energy into electrical energy; Simulation of installation parameters based on the organic Rankine cycle using the software package Smoweb software package. Results are a comparative analysis of the existing technologies for the production of thermal energy in the areas of decentralized energy and selected the most effective option for improving energy efficiency; was made thermal and technical and economic analysis of the use of technologies that allow to convert low potential thermal energy into electrical energy for the district heating systems DHS-22 of villages Podtesovo.
