Product Introduction
The water wall is the main heating component of the boiler, consisting of multiple rows of steel tubes distributed around the boiler furnace chamber. It flows water or steam internally while absorbing heat from external furnace chamber flames. Designed to primarily absorb radiant heat from high-temperature combustion products, it facilitates upward working fluid movement and heat-induced evaporation.
Originally developed for furnace cooling, water walls now serve as the primary heating surface in modern boilers due to their superior heat exchange capabilities. Large-capacity boilers particularly benefit, with water walls absorbing 40-50% or more of total boiler heat.
Key Advantages
  • Ensures furnace wall leakproofness and reduces combustion chamber air leakage
  • Provides complete combustion chamber water cooling, preventing coking during supplemental firing
  • Features minimal thermal storage capacity for rapid heating/cooling cycles
  • Top-supported design reduces framework load and facilitates overhang
  • Enhances tube heat absorption capacity compared to bare tubes
  • Factory-direct manufacturing improves component integration and reduces installation workload

Structural Classification
Plain Tube Type: Simplest structure using seamless steel pipes.
Membrane Type: Features welded fin tubes forming a sealed heating surface, improving airtightness and furnace protection.
Squeaked Tube Type: Incorporates welded pins for refractory application, ideal for difficult ignition or liquid slag discharge furnaces.
Layout variations include attached wall (single-side heating) and partition wall (double-sided heating) configurations for different boiler requirements.
Construction Details
Membrane water wall construction involves precise dimensional checks, specialized welding techniques to minimize deformation, and complex assembly for components like furnace bottoms and flame angles. Special attention is given to:
  • Dimensional adjustment of tube rows including width, length, and flatness
  • Specialized welding sequences to control shrinkage deformation
  • Complex assembly of rear water wall components with flame angles
  • Precision ball passing through specially configured piping systems
Manufacturer Profile
Hua Dong Boiler Co., Ltd. is a specialized boiler manufacturer established in 1985 with two manufacturing bases spanning 400,000 m². The company holds:
  • Grade A boiler and pressure vessel manufacturing licenses
  • ASME "S", "U", and "NB" stamps
