Abstract

The authors consider the problem of insufficient power of existing boiler houses and heat supply networks in large cities, which leads to overloads and accidents. Modernization of operation in heat supply system is aimed at improving energy efficiency, environmental safety and reliability of heat supply networks. The use of modern technologies provides a significant improvement in the operation of heat supply systems and makes the coolant more accessible and efficient for consumers. To ensure uninterrupted operation of heat supply facilities in residential areas and efficient operation of heat supply networks and heating mains in hard-to-reach areas with difficult terrain, the authors proposed to install or modernize booster pumping stations. Such stations help to keep the required parameters of the coolant and to provide heat consumers with quality coolant. The article discusses the operating principle of pumping stations and provides a functional diagram of process automation. Piezometric diagrams of preand post-installation of booster pumping stations allow us to speak about the positive effect of booster pumping stations modernization in the heat supply system. Thus, after reconstruction, the total capacity of pumping groups on the direct and return circuits increased by 1.33 times, the head in the system – by 1.12 times.
