利用《工业炉设计手册》公式7-51和7-52变形可得空气和烟气通过蓄热方式进行的热交换量和空气量、烟气量的关系式。进一步推导可得预热空气和煤气所需的烟气量。最后算得预热空气和煤气所需烟气量占总烟气量的比例。
Using the Industrial Furnace Design Manual, equations 7-51 and 7-52, the relationship between the amount of heat exchange and the amount of air and flue gas generated by air and flue gas through thermal storage can be obtained. Further deduce the amount of flue gas required to preheat the air and gas. The final count of preheated air and gas required for the proportion of total amount of flue gas.
