【摘要】 根据蓄热室结构特性,建立了高效蓄热室传热计算的数学模型。通过数值模拟和实验结果分析了蓄热体、换向时间等对废气的排放温度和空气的预热温度的影响,得出了本研究条件下,刚玉质小球的适宜换向时间为60s左右,高铝质和粘土质小球的适宜换向时间为20-30s。蓄热室温度效率可达到80%以上,热效率可达到70%以上。更多还原

【Abstract】 On the base of regenerator configuration character, the heat transfer mathematics models are set up. The effects of exhaust gas temperature and air preheat temperature influenced by regenerator medium, exchange time etc. are studied by numerical simulation and experiment. On the case, the suitable exchange time: corundum globule is about 60s, high aluminum and clay ceramic ball are 20-30s. Temperature efficiency is up more than 80%, thermal efficiency is up more than 70%.更多还原
