  • Boilers - University of Alabama

    Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must beLearn More

  • Working of Boiler – Explanation, Parts, Working Principle

    Boiler's classification is based on the following criteria: According to the Relative Passage of Hot Gases and Water. Fire-Tube Boiler: This is the one where the hot combustion gases are surrounded by the water. Water-Tube Boiler: In this, the water flows via the tubes, surrounded by hot combustion gases. According to the Arrangement of Water 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

  • Boiler Introduction | CleanBoiler.org

    In watertube boilers, boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Since tubes can typically withstand higher internal pressure than the large chamber shell in a firetube, watertube boilers are used where high steam pressures (as high as 3,000 psi) are required.Learn More
