Read moreTwo-Drum Bent Tube Boiler An upper and lower drum are interconnected by a number of tube banks. The furnace is surrounded by water tubes, which is often referred to as an "integral-furnace" because the furnace tubes are an integral part of the water circulation circuit. The integral design, not restricted to the two-drum boiler, has advantages
Read moreThe boilers have a variety of automated auxiliary equipment including electronically controlled air compressors and water control dampers, de-aerating and condensate tanks, and feed water pumps. The boiler plant is operational on a 24 hour/7 day a week basis.
Read moreFeb 26, 2013 · However, the boiler water immediately at the tube surface is considerably hotter than the bulk boiler water. As steam bubbles form near the tube wall, the soluble salts remain with the boiler water. This creates a localized high concentration of salts, even though the bulk boiler water may be well below saturation levels.
