摘要(Abstract):
中速磨煤机进行性能考核时,试验工况条件与设计工况条件会存在一定偏差,直接用试验工况条件下的磨煤单耗评价磨煤机设计性能不够准确和合理。以1台中速磨煤机性能考核试验为例,探讨磨煤机实际运行工况偏离规定的工况条件时磨煤单耗的校核与修正计算方法,使计算结果更为科学、合理,对磨煤机实际应用性能的评价更加准确。该磨煤单耗校核与修正方法也可为评价中速磨煤机的改造效果作参考。
There are certain deviations between test conditions and design conditions when the performance of a medium-speed pulverizer is evaluated. It is not accurate and reasonable to evaluate the design performance of a coal pulverizer with the unit power consumption under the test conditions. Taking a performance evaluation test of a medium-speed pulverizer as an example, the verifying and correcting calculation of the unit power consumption of coal pulverizer is discussed when the actual operating conditions of the coal pulverizer deviate from the prescribed operating conditions. The corrected result is more scientific and reasonable, and the actual performance evaluation of the coal pulverizer is more accurate. The unit power consumption calculation method can also be used as a reference for evaluating the retrofit effect of a medium-speed pulverizer.
