  • Finding the Root Cause of Boiler Tube Failures

    Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube failure.

  • Boiler Introduction | CleanBoiler.org

    General Boiler Information. 1 boiler horse power is about 42,000 BTUs of INPUT. 1 pound of steam is about 1,200 BTUs of INPUT fuel, and about 1,000 BTUs at the point of use, depending on the pressure of the steam. Low pressure steam is considered to be up to 15 psi; high is generally 100 psi and higher.

  • Commercial Gas Boilers - hotwater.com

    The water-cooled circuits carry boiling water, and the steam-cooled circuits carry steam from the drum. As a result, they operate near the saturation temperature corresponding to the drum pressure. Whether the boiler is being fired or shut down, considerable heat absorption or loss is necessary to change the temperature of the walls.
