Product Description
High-Performance Boiler Membrane Wall for Furnace Protection and Cooling
Product Introduce: Boiler Membrane Wall
The full name is "water-cooled wall pipe", formerly known as "water-cooled wall", also known as "rising pipe". It is usually laid vertically on the inner wall of the furnace wall, and is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace. It is the main type of evaporation heating surface of various modern boilers, and it is also the basic component in the boiler water circulation circuit. It is named because it has the function of cooling and protecting the furnace wall.
Advantages
| 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. |
According to the structural type, there are three main types: plain tube type, membrane type and squeaked tube type. The plain tube water wall is composed of a whole row of seamless steel pipes, and their structure is the simplest;The membrane water wall weld many rolled water-cooled fin tubes together with spot welding, so that they become a sealed combined heating surface, which can not only improve the air tightness of the furnace, reduce air leakage, but also better protect the furnace wall, reduce the weight of the furnace wall, simplify the structure;The water wall of the spur tube is to weld many pins with a length of 20~25mm and a diameter of 6~12mm on the water-cooled wall tube, and then apply chrome ore refractory plastic in order to reduce the heat absorption of this part of the water wall and increase the temperature of the combustion zone, it is suitable for occasions where fuel ignition is particularly difficult or some liquid slag discharge furnaces.
According to the layout part, there are two kinds of attached wall type and partition wall type (i.e., double-sided heating) water cooling wall. The former is mostly partially embedded in the inner wall of the furnace wall and absorbs heat on one side, while the latter is mostly installed in the middle of the furnace chamber of a large boiler, separating the whole furnace into two independent parts that are heated on both sides.
Features
1. Sturdy construction
2. High strength
3. Accurate dimensions
4. Corrosion resistant finish
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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
