Keep out of hot water when remotely monitoring boilers
Everyone recognizes the importance of maintaining the proper water level in boilers and other steam equipment. Operators have long relied on devices such as water-level gages, mounted directly to boiler drums or to safety water columns attached to the drums, to show the level of the water, thus enabling them to keep it at a safe level, and assuring optimum fuel utilization. Advances in monitoring and control systems have made it possible to do the job more easily and efficiently, with accurate water-level readings clearly on display to operators who may be up to 1,000 ft away from the steam equipment. Today, there are a number of types of remote level-indicating devices in the marketplace--including electric, fiber-optic, manometric, and mechanical systems. In this article, the author describes the advantages and disadvantages of each. But to put their use in context, the paper first considers the requirements of the ASME Boiler Code.
