摘　　要：针对常规热平衡法煤粉浓度测量存在动态误差的问题,提出对一次测量量进行变系数动态补偿的软测量方法。该方法提高了动态过程中的煤粉浓度的测量精度,提高了测量的实时性,保障了锅炉的安全经济燃烧。Aiming at dynamic error during measuring pulverized-coal concentration by general heat balance method,a dynamic compensation soft measurement method is introduced.The method improves pulverized-coal concentration measurement precision during dynamic process and gains good real-time performance,which ensures the safe and economic operation of boilers.

关 键 词：煤粉浓度 软测量 动态补偿
