Water wall panels are used in Waste Heat recovery boilers. We manufacture Water wall panels. These are fabricated out of carbon steel tubes to customers' drawings and specifications. Special care is taken for ovality and thinning at the bent portion, during fabrication.
We are manufacturing and supplying a comprehensive range of Waterwall Panels. The tubes offered by us are known to withstand a great internal pressure as a continual strip of fin material is wound spirally on the tube. These tubes are known to provide heat uniformly that result in an increased heat output.
The main function of water wall panels in boiler is to absorb the heat generated by high temperature flame or flue and to generate steam or hot water in tubes, hence to reduce the temperature in the chamber.

Product Introduction

Pinned water wall panels are typically installed vertically on the inner side of the furnace wall. Their main job? Soak up the radiant heat from the flame and hot flue gases inside the furnace. They’re the go-to evaporating heating surface in modern boilers and a key part of the boiler’s water circulation system. Why the name? Because they both cool down and protect the furnace wall.

Initially, water walls were designed just to shield the furnace from overheating, not to be heated themselves. But as people realized how well they transfer heat, they slowly replaced steam drums as the boiler’s main heating component.

Think of the water wall as a series of parallel pipes lining the boiler chamber. Their dual role is to absorb the intense heat from the furnace’s high-temperature flames and flue gases, turning water into steam or hot water inside the pipes. At the same time, they lower the furnace wall’s temperature, keeping it safe from damage.

In large boilers, where furnace flames burn extremely hot and radiate massive amounts of heat, the water wall is a heat - absorbing powerhouse. It soaks up 40 - 50% or even more of the boiler’s total heat. These days, almost all modern water tube boilers—except for some small ones—rely on water walls as their primary evaporative heating surface.

Advantages of Membrane Water Wall

1). To guarantee the leakproofness of furnace wall and reduce the air leak of combustion chamber.
2). To achieve the full water cooling of combustion chamber, and the boiler accessories membrane water wall is benefit to prevent coking under the condition of supplemental firing.
3). The thermal storage capacity is small, the warming of combustion chamber is fast and the cooling is also fast, which could shorten the cooling time of boiler’s start and furnace shut down.
4). It is good to adopt top supported water cooled wall and it could reduce the load of boiler framework, which is benefit to overhang.
5) Compared with the bare tubes, the membrane water wall improves the heat absorption capacity of tubes.
6) The factory direct boiler membrane water wall could improve the Preliminary combination degree of boiler parts and reduce the installation workload.

Note

1	Control of weld penetration to satisfy mechanical and heat transfer requirements Control of the deformation to acceptable tolerances.
2	Panels routinely require straightening in the workshop after welding and heat treatment, the question to be answered is can the shop then meet the required dimensional tolerances for successful site installation?
3	Can existing shop handling procedures be used as-is without adding excessive controls that will add cost and schedule.
4	The importance of preheating and its maintenance through the welding process could cause a number of handling and shop processing issues that will substantially increase cost.
