Abstract

Abstract: Based on the using experience of water level indicator with electrical contacts in a steam drum of waste heat boiler of S109FA gassteam combined cycle unit, the structure, the material, the environment and working characteristics of the water level indicator with electrical contacts were introduced; and the frequent leakage faults of the indicator were analyzed. In order to reduce the leakage fault and raise the reliability of measurement, some feasible solving methods were put forward.

Key words: steam drum of waste heat boiler, water level indicator with electrical contacts, electrical pole, leakage, reason analysis, solving method
