Abstract: The formation of new heat-supply systems is connected with the solution of problems concerning the change in structure of heat-generating sources with attaining higher technical and economic parameters, i.e., the synthesis of construction of heat supply systems throughout the entire chain from heat generation to its consumption. In the world experience, electricity generation at HPP is about 9%, and it is growing steadily.
However, heat and power plants in Ukraine are developing slowly, and their equipment is outdated, does not meet current environmental and economic requirements, and needs to be reconstructed, modernized or completely replaced. Furthermore, present decrease in the production of energy-intensive enterprises has led to the drop of consumption of technological steam from the industrial bleedings of turbines, i.e., to the underproduction of electric and thermal energy.
In view of the deterioration of power equipment and the absence of financial assets for its replacement, low-cost technologies are required for increasing the power and efficiency of heating and industrial HPP. Such modernization technologies include options with minimal investment, positive economic effect, and return of funds faster that after a year.
Keywords: thermal power engineering, heat and power plant, heat generation, centralization, low-cost technologies.
