Abstract

The paper presents a synthesis of research results on the development of scientific and methodo-logical support for the comprehensive solution of the main technical, economic and organizational problems of designing, functioning and development of modern district heating systems (DHS). These studies were conducted at the Melentiev Energy Systems Institute of SB RAS (Irkutsk city) by the scientific team of the Laboratory of Heat Supply Systems. Within the framework of the developed scientific and methodological support, the following basic problems were solved: optimization of levels of district heating in DHS with feasibility study for connecting new consumers, selection of optimal forms and models of heating market for DHS, comprehensive analysis and ensuring (optimization) reliability of DHS taking into account the fuel supply of heating sources (HS), and other additional problems. Based on the developed scientific and methodological ensuring following practical researches were carried out on existing DHS schemes of cities of the Irkutsk region: optimal management of DHS in Angarsk, Irkutsk region, taking into account the diverging interests of heating market participants; determination of the optimal scale of development of the existing DHS in Irkutsk based on the optimization of the effective heat supply radius taking into account the reliability of heating to consumers; comprehensive reliability analysis of DHS in Shelekhov of Irkutsk region, taking into account the fuel supply to HS.

Highlights

In Russia, heat supply has great social, economic, energy and ecological importance
The technique for territory zoning by type of heat supply was developed, which consists in dividing the urban area into zones of district and distributed heating based on the determination of the heat load density (HLD)
As a result of the provided researches, scientific and methodological ensuring was developed for the comprehensive solution of a number of key technical, economic and organizational tasks of designing, functioning and developing modern district heating systems (DHS), taking into account their relationship

Summary

Introduction

In Russia, heat supply has great social, economic, energy and ecological importance. Russia produces about 44% of the world total heat energy produced in district heating systems (DHS). The paper presents a synthesis of research results on the development of scientific and methodological support for the comprehensive solution of the main technical, economic and organizational problems of designing, functioning and development of modern DHS. These studies were conducted at the Melentiev Energy Systems Institute of SB RAS (Irkutsk city) by the scientific team of the Laboratory of Heat Supply Systems. The following is a thesis description of the main points of these methodological developments and the results of practical research (case studies) carried out using the developed methodological ensuring
