Alloy 38mm 76mm Water Wall Panels For Waste Heat Recovery Boilers

Product Specification

High Pressure Working Water Panels for Waste Heat Recovery Boilers

Product Introduction: Boiler water wall panel

Full name of "water wall tube", the old "water wall", also known as "rising pipe".Usually laid vertically on the inner wall of the furnace wall, it 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 evaporative heating surface of modern boilers and the basic component of water circulation loop of boilers.It has the function of cooling and protecting furnace wall.

Parameter

Functions

• The water wall was originally designed not to be heated but to cool the furnace against high temperatures.Later, because of its good heat exchange function, it gradually replaced the drum as the main heating part of the boiler.
• Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it 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 evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling and protection of the furnace wall, so the name.
• An evaporative heating surface arranged on the inner wall of a boiler furnace and composed of many parallel pipes.The function of the water wall is to absorb the radiant heat of the high temperature flame or flue gas in the furnace chamber, generate steam or hot water in the pipe, and reduce the temperature of the furnace wall to protect the furnace wall.In a large capacity boiler, the flame temperature in the furnace is very high, and the intensity of heat radiation is very large.40 to 50 percent or more of the heat in the boiler is absorbed by the water wall.Except for a few small capacity boilers, modern water tube boilers use water cooling wall as the main evaporative heating surface.

Advantages

1.ensure the sealing of furnace wall and reduce air leakage in combustion chamber.

2.realize full water cooling in the combustion chamber, which is conducive to preventing coking under the condition of intensified combustion.

3.low heat storage capacity, fast heating and cooling of the combustion chamber, which can shorten the cooling time of the boiler starting and stopping.

4.it is suitable to use tube-laying furnace wall, which greatly reduces the load of boiler frame and facilitates suspension.

5.compared with the light pipe, the heat absorption capacity of the pipe is improved.

6.improve the pre-assembly degree of boiler components, facilitate and reduce the installation workload.

Features

1. Strength calculation report with applied materials information;
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;
4. Hydraulic test report: ensure the standard working pressure and safet
