对高温空气燃烧技术中的关键设备———蜂窝陶瓷蓄热体换热器的热动态特性进行了实验测试。结果表明:蜂窝陶瓷蓄热体换热器的压力损失随着空气流速以及蓄热体长度的不同而变化,但总体上压力损失并不大;四通换向阀的换向周期、蜂窝陶瓷蓄热体换热器的体积等是影响其温度效率、热回收率等热性能的重要因素。
The key equipment of high temperature air combustion technology - honeycomb ceramic regenerator heat dynamic characteristics of the experimental test. The results show that the pressure loss of the honeycomb ceramic regenerator varies with the air velocity and the length of regenerator, but the overall pressure loss is not large. The reversing cycle of the four-way reversing valve, The volume of the heat exchanger is an important factor affecting the thermal performance such as temperature efficiency and heat recovery rate.
