Increasing the efficiency of energy generation at Krasnoyarsk CHP-2 by utilization of waste heat

[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 environmental pollution from the production of electricity and heat at the CHP. The aim of the work is to increase the energy efficiency of electric energy generation by upgrading the coal thermal power plant, reducing environmental pollution from the enterprise by reducing the amount of fuel burned at the same capacity. Research methods are Analysis of existing technologies for utilization of low-potential thermal energy in the energy sector; Thermal, technical and economic analysis of technologies that allow converting low potential thermal energy into electrical energy; Simulation of installation parameters based on the organic Rankine cycle using the Smoweb software package; Analysis of modern manufacturers of organic Rankine cycle technology in order to select the most suitable. Results are a comparative analysis of existing technologies for utilization of low-potential heat energy was carried out and the most effective option for energy efficiency was chosen. Heat and techno-economic analysis of the application of technologies to convert low-grade thermal energy into electrical energy was performed; modeling installation using the principle of organic Rankine cycle utilizing heat energy from the boiler BKZ-420-140-PT1 was designed.
