Development and research of 5.1 and 7.1 MW hot water boilers for heat supply of industrial and residential buildings

Abstract

The article considers the development and research of hot water boilers with a capacity of 5.1 and 7.1 MW, intended for use in heat supply systems of industrial enterprises and residential buildings. The relevance of the topic is due to the need to improve the energy efficiency, reliability and sustainability of modern heat engineering installations in the context of increasing requirements for environmental and economic efficiency. The main objective of the work is to create technologically advanced hot water boilers capable of providing stable heat supply with minimal resource costs. As part of the study, optimal technical parameters of boilers were developed considering the requirements for power, thermal efficiency, automation and operational safety. Modeling of working processes was carried out in order to analyze heat engineering characteristics and assess the efficiency of heat exchange under various operating modes. Particular attention is paid to the use of energy-saving solutions aimed at reducing heat losses and improving environmental performance. The results of the study can be used in the design and modernization of heat supply facilities, as well as in the development of regulatory requirements for modern heat engineering equipment.
