Vol.212. ID: 02005. 2018. DOI: 10.1051/matecconf/201821202005 A method for determining the optimal action zones of the centralized sources of thermal energy is developed using the calculation of the effective heat supply radius of consumers. The methodology allows to take into account the features of heat supply systems' functioning, their technical and economic indicators, the uneven distribution of heat loads throughout the city, and limitations on the reliability ...

The main objectives of this research were to assess the impact of the deicing agent on initiation and acceleration of corrosion of the heat network equipment (pipelines, nonmobile and sliding bearings), the effect of this corrosion on reliability of heat supply to consumers, and to determine the economic damage caused by the decline in service life of pipelines. In addition, the study identified additional circumstances of the detrimental effect of deicing agents on the heat network infrastructure ...
