Abstract:The failure and retrofit to water level measuring system on drum of boiler sized of 670 t/h were introduced. The optimization of primary measuring elements on boiler dram level measuring system, and the method to eliminate level measuring offset on drum level indicator of super higher pressure boiler were analyzed to fix the problem of boiler drum level protection failure and the issue of boiler operation under high level.
Keywords:dram level  measuring difference  primary measurement  configuration optimization
