Advantage Boiler Rifled Water Wall Tube

Product Related Information

  • Experimental and theoretical analysis on the safety

    Small pressure drop of the water wall is also desirable for a utility boiler in addition to its excellent heat transfer characteristics. Given the rotational flow, the pressure drop of the internally rifled tube is much larger than that of the smooth tube at the same mass flux. Thereby, the use of low mass flux is expected.
