Analysis on the problems in Drum Water Level Measurement in Han Chuan Power Plant

汽包水位作为表征锅炉安全运行的重要参数,汽包水位测量的准确性和可靠性是实现汽包水位自动控制的前提,是防止汽包满水、缺水,防止汽轮机进水的重要保证。正确安装、及时检修维护、及时解决存在的问题和故障,是汽包水位测量能够长周期可靠运行的保证。通过对汉川电厂的汽包水位测量存在的问题进行分析,总结了存在的问题,探讨消除偏差的改进措施。

Drum water level is an important parameter to characterize the safe operation of the boiler. The accuracy and reliability of the drum water level measurement is the premise to realizeautomatic control of the drum water level, and is an important guarantee to prevent the drum fromfull of water, water shortage and steam turbine water intake. Correct installation, timely repair andmaintenance, timely solution to the problems, timely troubleshooting, are the guarantee oflong-term reliable operation of the drum water level measurement. The problems existing in thedrum level measurement of Hanchuan Power Plant are analyzed in this paper, the existing problemsare summed up and the improvement measures to eliminate the deviation are discussed.
