The working project is intended to increase the energy efficiency of the centralized heating system of consumers by reconstructing the heating networks from the boiler house "KMK" in the area from the left "wing" of the pumping station No. 60 (TRP-60) to consumers, which are residential buildings and buildings in blocks 285-287, which are characterized by high rates of heat energy losses and unsatisfactory technical condition. Additional land acquisition is not required.

. High level of physical wear and tear of heating networks Problem: Existing district heating networks have been in operation for a long time, have significant physical and moral wear and tear, which leads to frequent accidents, coolant leaks and increased heat energy losses. Solution result: Replacing worn pipelines with new pre-insulated networks has reduced the accident rate, increased reliability and extended the period of trouble-free operation of heating networks. 2. Significant losses of heat energy during transportation Problem: Insufficient thermal insulation of existing pipelines causes significant heat losses during transportation of the coolant from the boiler room to consumers. Solution result: The use of modern pre-insulated pipes has significantly reduced heat losses and brought them to regulatory values, which ensures savings in heat energy and fuel. 3. Frequent coolant leaks and excess feed water consumption Problem: Leakage of connections and corrosion damage to pipes lead to constant coolant leaks, increased feed volumes and additional costs for water preparation. Solution result: Reconstruction of networks ensured the tightness of the system, which allowed to reduce coolant losses, reduce water and chemical reagent consumption. 4. Violation of the hydraulic regime of the heating network Problem: Mismatch of pipeline diameters with actual thermal loads led to uneven distribution of coolant and excess electricity consumption by pumping equipment. Solution result: Optimization of routes and pipe diameters ensured a stable hydraulic regime, reduced hydraulic losses and contributed to a decrease in electricity consumption. 5. Difficulty in locating accidents and carrying out repairs Problem: The lack of modern shut-off valves made it difficult to quickly disconnect individual sections of the network, which led to the disconnection of a large number of consumers. Solution result: Installation of modern shut-off and control valves provided the possibility of local disconnection of emergency sections, reduced repair time and minimized inconvenience for consumers. 6. Low reliability of heat supply during the heating season Problem: Frequent accidents and unstable coolant parameters negatively affected the quality of heat supply to residential buildings and social facilities. Solution result: After the project was implemented, stable heat supply parameters were ensured, the comfort of the population and the reliability of the entire system were increased. 7. High operating costs Problem: Constant emergency and restoration work and energy losses caused significant operating costs for the enterprise. Solution result: Reducing heat energy losses and accidents led to a reduction in operating costs and an increase in the economic efficiency of the heating networks. Overall result The implementation of the project to reconstruct the district heating networks from the KMK boiler house allowed us to comprehensively solve technical and energy problems, ensure energy savings, increase the reliability of heat supply and create the prerequisites for the sustainable operation of the heat supply system in blocks 285–287 of the Metallurgical District of Kryvyi Rih.
