Qualitative and quantitative analysis of small scale thermal energy in Russia

Abstract

THE PURPOSE. Perform a review of information sources on the state of small-capacity thermal power in Russia when the unit capacity of steam turbine, gas turbine and gas piston units is less than 25 MW. Evaluate the information sources of the authors of publications that provide statistics for small-scale energy facilities. Make an assessment of the state of small-scale energy in Russia based on a specific list of objects maintained by the authors over the past 25 years. Consider the manufacturers and characteristics of different types of aggregates, as well as the schemes for integrating aggregates into the thermal schemes of existing sources. METHODS. Statistical indicators of small-scale energy facilities presented in tabular form in Excel are determined based on the built-in functions of this program. RESULTS. The production and characteristics of modern units based on steam turbines are considered. Practical schemes for integrating counter-pressure steam turbo generators into the thermal schemes of existing heat sources are presented. Russian and foreign manufacturers and characteristics of electric units based on gas turbines and internal combustion engines operating on the Otto cycle are considered. Thermal diagrams of gas-turbine and gas-piston units producing both electric and thermal energy are given. A statistical analysis of the list of small-scale cogeneration and power plants of simple cycle compiled by the authors is performed. The number of stations of different types, their distribution by total capacity, regions, industries, and years of commissioning are determined. CONCLUSION. It is shown that gas-turbine and gas-piston installations with a total capacity of up to 80% play a decisive role in the structure of small thermal energy. Quantitative indicators - the total number of stations of small-scale power facilities is about 1500 units and the total electric capacity is more than 18 GW allow us to get an idea of the significant role of small-scale heat power in Russia. Quantitative indicators for solar and wind power plants in the country are also considered.
