  • Firetube boilers - Industrial Boiler & Mechanical

    Firetube boilers operate by sending combustion/flue gas through a series of straight tubes surrounded by hot water stored in the same vessel. Often identified by the number of passes used (such as a 3-pass or 4-pass firetube boiler), this refers to the number of times combustion gas flows the length of the pressure vessel as it transfers heat to the water.

  • 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.
