| Abstract: | The heat recovery rate, optimal switching time and pressure drop of honeycomb regenerator used in the high temperature air combustion system were investigated. In order to modify the measured heat recovery rate, air feeding efficiency that was denned as the proportion of the real air flow rate through the honeycomb to the total flow rate was presented. The experimental results provide a basis for application and design of honeycomb regenerator. |

| Keywords: | honeycomb regenerator air feeding efficiency heat recovery rate optimal switching time |
