  • Reasons why the water is bouncing in the gauge glass, and

    Jun 25, 2014 · When the steam bubbles condense, the water in the boiler falls to a point lower than the water in the gauge glass. The water in the gauge glass offsets this by falling into the boiler. This usually turns on the low-water cutoff or the automatic water feeder. You wind up with nagging water level problems in the boiler.Get Price

  • Reasons why the boiler water is dirty, and where to look

    Jun 24, 2014 · That forces water up into the returns where it meets steam and creates water hammer. The water hammer can dislodge even more corrosion, which eventually washes down to the boiler and discolors the water. When these things begin to happen, dirty water is usually the least of your problems. Find the source of the excess feed water and get rid of it.Get Price

  • Groundwater | Dissolved mineral sources and significance

    Water from some formations contains considerable iron in solution, which, on being exposed to the air, precipitates readily and gives a red-water effect. Acids and strong bases are capable of causing corrosion, and, together with an extreme pH, they support electrochemical processes that cause deterioration of water pipes, steam boilers, and Get Price
