The water wall is a key heating element in the boiler, made up of multiple rows of steel tubes arranged around the furnace chamber. Inside these tubes, water or steam circulates, while outside they absorb heat from the flames in the furnace.
Its main role is to capture radiant heat from high-temperature combustion gases, helping the fluid inside move upward and gradually turn into steam through heating.
Originally used mainly for cooling the furnace, water walls have evolved into the primary heating surface in today's boilers thanks to their efficient heat transfer. They are especially important in high-capacity boilers, where they can absorb 40% to 50%—or even more—of the total heat in the system.
- 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
- 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
- Grade A boiler and pressure vessel manufacturing licenses
- ASME "S", "U", and "NB" stamps
- ISO9001, SO3834, and EN12952 certifications
