coefficient of thermal conductivity

This paper highlights the main causes of heat losses in heat networks and methods, that can significantly reduce heat losses, which means to increase the efficiency of heat supply systems.

The results of experimental research on determination of thermal and technical characteristics of pre-insulated pipes are presented in the paper. Experimentally, the data on the thermal conductivity of the closed-cell foam samples were obtained.

Conducted calculated and experimental research of thermal processes and storage capacity of solid heat storage materials. Analyzed the change of the thermo physical properties of the selected heat storage materials depending on temperature. Estimated specific heat storage capacity in the temperature range from 50 °C to 650 °C such materials: magnesite, chamotte, dinas, corundum.
