  • Boiler (power generation) - Wikipedia

    From 1804 onwards Trevithick produced a small two-pass or return flue boiler for semi-portable and locomotive engines. The Cornish boiler developed around 1812 by Richard Trevithick was both stronger and more efficient than the simple boilers which preceded it. It consisted of a cylindrical water tank around 27 feet (8.2 m) long and 7 feet (2.1 Learn More

  • Difference Between Two Pass Boiler and Three Pass Boiler

    Dec 20, 2009 · In the case of the two pass design, the gas flow takes a turn from the furnace outlet through a small horizontal pass to the second pass where a part of the superheater surface, sometimes even a portion of reheater surface and economizer surface, is accommodated.Learn More

  • Boiler Efficiency | CleanBoiler.org

    In the two-pass boiler configuration, radiant pendant surfaces are located above the furnace, and convective surfaces are arranged horizontally in the second pass, enabling reduced height of the furnace and simple element support structure. The two-pass configuration is available with both spiral and vertical wall design.Learn More

  • Turbulators | CleanBoiler.org

    For example, a two-pass boiler provides two opportunities for hot gases to transfer heat to the boiler water. Hot combustion gases enter the tubes in a turbulent flow regime, but within a few feet, laminar flow begins and a boundary layer of cooler gas forms along the tube walls. This layer serves as a barrier, retarding heat transfer.Learn More
