Boiler Waterwall Panels

Product Description

Boiler Water Wall Panels Full Overview

Boiler water wall panels are vertical arrays of tubes placed along the inside walls of a boiler furnace to absorb radiant heat from the combustion process. They form a heat-absorbing enclosure around the furnace and are a critical part of modern water-tube boilers.

 What Are Water Wall Panels?

Water wall panels consist of closely spaced boiler tubes that carry water or steam-water mixture, welded together with fins or membrane strips to form solid, gas-tight panels. They are exposed to direct radiation from the flame and act as:

• Structural enclosure of the furnace

• Primary heat absorbing surface

• Pathway for water circulation to generate steam

Construction Features:

Materials Used:

• Tube Material:

  • SA-210 Gr A1 (carbon steel)

  • SA-213 T11, T22 (for higher temperature zones)

  • Stainless steel (in corrosive or high-temp zones)

• Filler Strip (Membrane/Fins): Same or compatible alloy as tubes

 Types of Water Wall Construction:

Functions:

1. Absorb Radiant Heat Account for 30 to40% of total heat transfer in the boiler

2. Steam Generation Water inside the tubes begins to boil and form a steam-water mixture

3. Protect Furnace Walls  Prevent damage from extreme heat

4. Improve Efficiency By converting radiant heat directly into steam
