Evaluation of the thermal efficiency of a high-temperature heat-insulation structure based on honeycomb plastic

Abstract

Highly efficient heat-insulation materials are needed in order to reduce the heat losses in operation of heat-power equipment at temperatures up to 700°C. A review of the available solutions showed that the development of a high-temperature heat-insulation structure of a new type is needed. The basic features of application of honeycomb plastics in heat insulation of heat-power equipment are discussed, the known techniques for evaluating the heat conductance of such materials are reviewed, and the results of calculation–parametric studies on determining the optimum honeycomb design for heat-insulation structures are reported.
