Customized Waste Heat Boiler Solution Rustproof Membrane Water Wall Panels
Why use membrane structure?
①Eliminates refractory maintenance ②15-20% higher thermal efficiency ③Reduces air leakage.
Application
| 1 | Energy saving enviromental protection china supplier membrane water wall for CFB boiler are membrane walls that are made of tubes welded together with or without a strip of metal in between. |
| 2 | These walls form the enclosure of the coal combustion chamber. |
| 3 | Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler. |
Product Introduction
Water wall panels with pins are typically installed vertically on
the furnace’s inner wall. Their main job? Soak up the radiant heat
from the flame and hot flue gas 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. The name comes from their
dual role of cooling and protecting the furnace wall.
Originally, water walls were just meant to shield the furnace from
overheating, not for heating. But as people realized how well they
exchanged heat, they started replacing steam drums as the boiler’s
main heating component.
Picture this: an evaporative heating surface made of parallel
pipes, lining the boiler chamber’s inner wall. That’s the water
wall. It absorbs heat from the high - temp flame and flue gas,
turning water into steam or hot water inside the pipes. Plus, it
keeps the furnace wall cool, protecting it from damage. In big
boilers, where the flame burns super hot and heat radiation is
intense, water walls soak up 40 - 50% or even more of the boiler’s
heat. These days, almost all modern water tube boilers—except for
some small ones—rely on water walls as their main evaporation
heating surface.
Description:
- 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.
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. |
