  • Water-tube boiler - Wikipedia

    The older fire-tube boiler design, in which the water surrounds the heat source and gases from combustion pass through tubes within the water space, is typically a much weaker structure and is rarely used for pressures above 2.4 MPa (350 psi). A significant advantage of the watertube boiler is that there is less chance of a catastrophic failure Get Price

  • Boiler Efficiency - an overview | ScienceDirect Topics

    The three main factors in determining efficiency are therefore flue-gas exit temperature, excess air and burnout, all of which are dependent on the technology. The flue-gas exit temperature is related to boiler design rather than the combustor. A well-designed boiler can achieve low exit gas temperatures for any of the technologies.Get Price
