How & Why Are Water Softeners Used in Steam Boilers?
One of the most important accessories you can have for your steam boiler is a water softener, which serves several purposes and plays a crucial role in helping your boiler avoid malfunctions and run more efficiently. Let’s go back to the basics and walk through how water softeners are used in steam boilers.
Water that comes from your city’s water treatment plant usually contains small amounts of dissolved solids, such as minerals like calcium and magnesium, that can cause damage to the tubes inside steam boilers. If these minerals are present in the boiler’s water supply, it can lead to hard scale buildup on the surface of the tubes, which has the potential to reduce the water heat transfer, ultimately overheating the tubes.
The efficiency of a boiler can also be negatively affected by hard water. If the presence of calcium and magnesium causes hard scaling, it will have an impact on the heat transfer inside the boiler. A layer of hard scaling as small as 1/8 of an inch on boiler tubes can decrease efficiency by as much as 25 percent. This will only make the boiler work harder and consume more fuel in order to meet your steam needs.
The solution to both of these potential problems is a water softener working in conjunction with your boiler. Water softeners will introduce sodium compounds into the boiler’s water supply to negate the presence of any calcium and magnesium, effectively resolving the hard water problem. A water softener will reduce the risk of hard scaling inside the boiler, improve the flow of water, ensure maximum levels of efficiency, and help your boiler avoid failures or any kind of damage that could reduce its lifespan.
A Miura water softener can be integrated with a boiler’s control panel and monitoring system. A hardness detection system can also be installed to automatically test the hardness of the boiler’s water supply. If necessary, the water softener will be activated to inject sodium compounds into the water in order to balance out the hardness. This is the easiest way to identify that hard water is a problem and address the problem.
