MODERNIZATION OF HYDRAULIC MODES OF HEATING NETWORKS IN TYUMEN

The article presents a proposal for solving the problem of excessive temperature of the return line based on the results of the study of the hydraulic modes of heat networks from the Tyumen CHP-2. The authors propose a modernized scheme of a group heating point (GHP), which is installed at the border of the balance of the main and district heating network. For this scheme, a physico-mathematical model is created, the purpose of which is to derive a modernized formula for the mixing ratio for a GHP, with which it is possible to determine the necessary actions to increase the efficiency of heat supply system control and the amount of time required for this. The calculation is made for the existing heat chambers of the city of Tyumen using the GHP scheme, the results of which revealed certain patterns.
