Jul 12, 2016 · Conversely, in a water tube boiler the water is inside the tubes and the heat source is on the outside. This ability for rapid heat transfer makes water-tube setups ideal for applications with variable load requirements and high pressure demands. Water tube boilers are available in significantly larger capacities than fire-tube style models.
All large and many intermediate-sized boilers are water-tube boiler with a boiler section that consists of closely-spaced water tubes covering the furnace wall. The waterwall boiler design allows much lighter, less expensive walls by having the waterwalls form an integral part of the boiler wall so that the wall is water cooled.
MJC Series. The MJC is a smoke tube type composite boiler. The exhaust gas section and oil section are arranged in parallel in order for the boiler to be installed in the duct with minimum installation space.
Most water-bearing tubes used in boiler construction are fabricated from low-carbon steel. However, steam-bearing (superheater and reheater) tubes are commonly fabricated from low-alloy steel containing differing levels of chromium and molybdenum. Chromium and molybdenum increase the oxidation and creep resistance of the steel.
