  • An Introduction to Treatment of Steam Boiler Water

    Fire tube boilers pass fire and hot combustion gas through the interior of the boiler tubes to heat the water that surrounds the tubes (see Figure 1.1). This type of boiler design is commonly used for factory-assembled (package) boilers, which are low pressure. 1.1.1.3 WATER TUBE BOILERS. Water tube boilers pass water through the boilerLearn More

  • Water Tube Boilers | Spirax Sarco

    Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …Learn More

  • Steam drum - Wikipedia

    A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.Learn More

  • Finding the Root Cause of Boiler Tube Failures

    Symptoms: Localized wall loss on the inside diameter (ID) surface of the tube, resulting in increased stress and strain in the tube wall.. Causes: Caustic attack occurs when there is excessive deposition on ID tube surfaces.This leads to diminished cooling water flow in contact with the tube, which in turn causes local under-deposit boiling and concentration of boiler water chemicals.Learn More

  • How a Water Tube Boiler Works | Miura America

    With the water tube design, the water is surrounded by heated gases rather than the other way around. The hot gas moves from the firebox into the boiler's main chamber. In some cases, the gas will hit the back wall of the boiler and then bounce back toward the other end of the boiler. This creates a superheater effect inside the boiler, which Learn More

  • Characteristics of Water-Side Deposits in Boiler Tubes

    Another problem associated with water chemistry and water-side deposits is the corro- sion of the tube. A common corrosion problem is the pitting of tubes due to the ingress of oxygen into the boiler water. The oxygen tends to attack welds and backing rings preferen- tially and can lead to eventual failure. In addition there are two major types Learn More
