Abstract
The district heating system of Karaganda (Kazakhstan) is considered in the article. The characteristics of the existing cogenerators and the state of the pipeline networks are given. Given the analysis of the existing state of the entire district heating of Karaganda. Proposed the program for the integrated development of the heat supply system bringing world experience in implementing the main development and modernization of heating networks. Shown the experience of reconstruction of heat supply facilities in the city of Karaganda within the framework of the state loan program “Nurly Zhol”. Based on the statistical data on the development of the city of Karaganda and its heat supply system the predicted heat loads are given until 2030. Due to the shortage of available heat capacity, options for the development of a centralized heat supply system in Karaganda are given and analyzed.
Highlights
The USSR held leading positions in the world in the implementation of a district heating system based on cogeneration district heating
Thermal power plants were built in all major cities, from which district heat supply was provided to residential microdistricts and industrial facilities
Using the obtained statistics and based on the experience of implementing the heat supply system development program in Karaganda, we will consider some promising options for the future district heating system in the region
Summary
The USSR held leading positions in the world in the implementation of a district heating system based on cogeneration district heating. Thermal power plants were built in all major cities, from which district heat supply was provided to residential microdistricts and industrial facilities. In Kazakhstan, heat supply in 30 large cities including the city of Karaganda is built on Soviet principles. The city of Karaganda, founded in 1934 and actively growing and developing in the 60-90s, was the center of the coal industry of Kazakhstan and all the Central Asia. The main source of district heating in the city of Karaganda are two power plants of combined electric and thermal energy production (TPS-1 and TPS-3), as well as about 440 individual heat sources (industrial and municipal boilers and autonomous heating systems) with a capacity of 0,1 to 54 Gcal/h. There is a large number of heating stoves for individual low-rise buildings that produce up to 390 Gcal/h
