Water Wall Panels
Water wall panels are used in modern industrial boilers to replace steam generating tubes. They are designed to absorb high temperature radiant heat given off by the flame in the fuel chamber, and reduce heat loss caused by the air tightness. We manufacture boiler tubes of the water wall panels in a variety of shapes and sizes to meet customer requirements, and all are processed using automatic fin to tube welding machines and large tube benders.
Materials for water wall panels
20# Steel, SA192, SA 106B, 15CrMoVG, 12Cr1MoV
Standards
ASME Code standard, GB Standard
Quality inspection
MT, RT, Hydraulic test
Various Boiler Water Wall Panel Can Be Fabricated
- Membrane boiler water wall panel: spot welds many rolled finned tubes into a sealed combined heating surface, which improves the airtightness of the furnace and reduces air leakage.
- Studded water wall tubing: welds pins of 20 to 25 mm in length and 6 to 12 mm in diameter on the water wall tube, and then applies a chrome ore refractory plastic to reduce the water wall panel’s heat absorption, and increase the temperature in the combustion zone. It is appropriate for situations where it is difficult to set fire to the fuel, as well as specific slag tapping furnaces.
- Plain tube boiler water wall panel: composed of a whole row of seamless steel pipes, the simplest structure.
- Wall-attached boiler water wall tubing: embedded in the inner wall of the furnace wall, single-sided heat absorption.
- Double-sided heated water wall panel: installed in the middle of the large boiler furnace, which is divided into two parts that are independent of each other, and both sides are heated.
Production in Huadong Boiler Factory
Case Study
A client from Thailand purchased 72 tons membrane water wall with 60 tube rows for boiler maintenance, which is made using 20G stainless steel and Q235B steel flat bar.
