Impact of deicing agents on heat network corrosion

... consequences of deicing agents application to urban roads for the heat network infrastructure. 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 ...

Thermal Transients in District Heating Systems

... heat producing source (heat plant). We study the latter scenario, commonly used for operations in Russia and Nordic countries, and analyze dynamics of the heat front as it propagates through the system. Steady velocity flows in the district heating pipelines are typically turbulent and incompressible. Changes in the heat, on either consumption or production sides, lead to slow transients which last from tens of minutes to hours. We classify relevant physical phenomena in a single pipe, e.g. turbulent ...
