Proper Employment Of Guided Wave Radar In Steam Loops By Keith Riley and Ravi Jethra, Endress+Hauser, Inc.
The heart and soul of any boiler-based power generation system is the steam loop or circuit. Without the proper availability of water in this system, efficiency suffers. In more extreme circumstances damage to other components from either too much water (carryover) or too little water (low water condition) will occur and shorten a boiler’s lifespan. In the most extreme situation a dry fire accident could occur resulting in severe damage and personal injury. This paper will address the application of Guided Wave Radar (GWR), also known as Time Domain Reflectometry (TDR), in your steam loop. Included will be discussions of how this technology functions and differs from more traditional forms of level indication.
