Super Heater Tube Rupture In Oil Fire Boiler

  • Boiler turbe failores

    26/9/2013 · A super heater is a device which heats steam to high temperatures. A super heater consists of group of tubes made of special alloys such as chromium –molybdenum. The wet steam from the boiler drum enters in to the super heater and gets heated up to

  • Superheater - Wikipedia

    A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in

    Boiler tubes can undergo sudden failures by rupture or leakage and is usually detected while in operation rather than during a hydro test or other inspection activities. This calls for immediate action as it can often cause a shutdown of the boiler, leading to loss of production and downtime.

    For example, in a super-heater of SA192 tubes, with a designed metal temperature of 800 o F, the ASME Boiler and Pressure Vessel Code gives the allowable stress at 800 o F as 9,000 psi. If the tube-metal temperature should rise to a temperature of around 1300 o F, the hoop stress would be equal to or slightly greater than the tensile strength at 1300 o F, and failure would occur in a few minutes.
