Récapitulatif: Discover the Pin Type Barbed Boiler Water Wall with Refractory Coating NDT, designed for high-efficiency heat transfer and durability in boiler systems. This video covers its welding process, features, and applications in modern boilers.
Caractéristiques Du Produit Connexes:
  • Pin type water wall with welded round steel for secure refractory coating attachment.
  • Forms fire belts, liquid slag discharge furnace sections, and cyclone furnace cylinders.
  • Uses inner threaded pipes for enhanced heat transfer in high-heat zones.
  • Prevents boiling heat transfer deterioration by disturbing steam-water mixture flow.
  • Main heating surface of boilers, absorbing radiant heat from high-temperature combustion.
  • Available in bare tube, membrane, and prick tube structural types.
  • Ensures cooling and protection of furnace walls in boiler systems.
  • Requires precise weld penetration and deformation control for optimal performance.
Les questions:
  • What is the purpose of the refractory coating on the Pin Type Barbed Boiler Water Wall?
    The refractory coating is firmly laid on the water wall using pins to form fire belts, liquid slag discharge sections, and cyclone furnace cylinders, enhancing durability and heat resistance.
  • How does the inner threaded pipe improve heat transfer in the water wall?
    The inner threaded pipe creates strong disturbance in the steam-water mixture, forcing bubbles away from the wall and preventing heat transfer deterioration, thus lowering the tube wall temperature.
  • What are the key considerations during the welding process of the water wall panels?
    Key considerations include controlling weld penetration for mechanical and heat transfer requirements, managing deformation tolerances, and ensuring proper preheating to avoid handling and cost issues.
