Study of factors affecting reliability and efficiency of heat supply system

Abstract

Reliable and uninterrupted supply of heat to consumers is the most important task of the heating system. Due to the connection to the heat network of a large number of dissimilar consumers, the heat supply system operates year-round. Damage to heat networks can lead to disconnection of consumers, disruption of internal engineering systems, and reduction of their operation parameters, which can be dangerous, especially during the heating period at low outdoor temperatures. To ensure the reliability and efficiency of the heat supply system, it is necessary to fulfill all the requirements of the technical operation rules, conduct timely rounds and inspections and identify damage to the heating network at an early stage. It is also necessary to identify factors affecting the reliability and, consequently, the efficiency of the heating system, identifying “risk zones” by the magnitude of damage, based on the results of the calculation. As well as the development of measures to identify and prevent failures in the heating system.

Pathways for sustainable development of urban heat supply systems

“…The total length of heating networks in one-pipe calculation is about 15 thousand km. Taking into account the seasonal unevenness of heat consumption, the average annual power utilization rate of heat sources is 21% [7,14,15]. The Moscow region has the highest heat load in the world.…”

Integrated efficiency evaluation of the heat- supplying enterprises activity

“…Reliable and uninterrupted heat supply for consumers is the most important problem of the heat supply system. It creates the basis for forming of comfortable living environment at low values of temperature of the external air [1]. Heating during a certain period (from 2...3 to 9...12 months) is required on the most part of the planet.…”

“…Research interest also considers the matters of reliability of heat supply and risk management of the heat-supplying organizations; that is reflected in some publications on this subject [1,7,8].…”
