| Popis: | We investigated the reasons of obstruction in elements of heating systems equipped with capacitive heating devices, which leads to an increase in hydraulic resistance, a decrease in the coolant flow rate, a decrease in the average surface temperature of the heater and a decrease in its heat transfer. We studied the decrease in the thermal conductivity of the pipeline walls of the heating system depending on the thickness of the sediment of solid particles on their surface. The analysis of the existing method of flushing heating system is carried out and its shortcomings are revealed. A better method for flushing single-pipe heating system hydraulically is proposed, which involves the following: to ensure effective flushing of capacitive heaters, it is proposed to supply clean water and to remove wastewater from different sides of the heating device. The application of the proposed method allows us to reduce the water consumption for flushing heating system, to reduce the flushing time, to exclude the transfer of solid particles to other elements of the heating system which improves reliability of its operation. |
