一种基于质量守恒的三分仓回转式空气预热器漏风率测试和修正方法研究

A Methodbased on Mass Conservation for Test and Correction on Leakage of Three-Sectional Regenerative Rotary Air Heater

漏风率是回转式空气预热器的重要性能指标。在ASME PTC4.3《空气预热器试验规程》中关于漏风量修正的基础上提出了一种适用于三分仓回转式空气预热器的漏风率修正方法,通过该修正方法,可对三分仓回转式空气预热器密封改造后的效果进行更加有效的漏风率指标评价。

Leakage rate is an important performance index The correction method of leakage rate for tri-sector air heater was proposed on the basis of leakage correction in ASME PTC4. 3（Test Code For AIR HEATERS）. By this correction method, the more effective evaluation of leakage rate could be used on evaluating the result of seal reform of tri-sector air heater.
