摘　　要：大容量锅炉锅筒两侧普遍存在着水位测量偏差 ,影响着机组的安全运行 ,作者分析了水位偏差产生的根源 ,介绍了使用均压管降低测量偏差的经验和效果 ,给出了在设计和运行上防治水位测量偏差的措施。A recurrent problem in recent years is the measurement discrepancy in water level indication at the two ends of the drum of a large sized boiler. This can affect the safe operation of a power plant. After an analysis of the root cause of this deviation the authors present their successful experience in employing uniform pressure tubes for coping with the issue and recommend some effective measures both in design and operation aimed at reducing the discrepancy of water level measurement.
