摘要

基于华能平凉发电公司1号炉汽包水位多测孔技术改造的成功经验

分析了汽包水位测量的原理和提高测量准确性的方法。改造无需在汽包壁上开孔

可使各水位计测量互不干扰

减少了测量偏差

提高了汽包水位保护控制的可靠性。

Abstract

Based on the successful experience of multi-orifice technical retrofit for measuring water-level in the drum of boiler no.1 in Huaneng Pingliang Power Generation Co Ltd

the principle for measuring water-level in boiler drum and the method for enhancing the precision of measurement have been analysed.It isn't necessary to bore holes on the wall of drum

the measurement of each water-level indicater can not mutually interfered

decreasing the deviation of measurement

enhancing the reliability of protection control for water-level in the boiler drum.
