摘要
实验研究了高温空气燃烧系统使用的蜂巢蓄热体热回收率、最佳换向时间、流动阻力等性能参数及其随几何尺寸的变化规律;提出供风效率的概念,表征流经蓄热体的实际供风量与总供风量的差别,并对热回收率进行了修正。本试验为蓄热体应用与设计提供了依据。
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.
