Coal Steam Boile Wall Water Panel Good Heat Exchange Function

Coal Steam Boiler Spare Parts Seamless Steel Membrane Water Wall Panel carbon steel alloy

Membrane Water Wall Panel Product details

1. 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.

2. It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.

3. Because of both cooling and protection of the furnace wall, so the name.

4. The water wall was originally designed not to be heated, but to cool the furnace from high temperature damage.

5. Later, because of its good heat exchange function, it gradually replaced the steam drum as the main heating part of the boiler.

6. The evaporative heating surface, which is laid on the inner wall of boiler chamber and consists of many parallel pipes.

7. The function of water wall is to absorb the radiant heat of 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.

8. In a large capacity boiler, the flame temperature in the furnace is very high, the intensity of heat radiation is very large.

9. Forty to fifty percent or more of the heat in the boiler is absorbed by the water wall.

10. Except for a few small capacity boilers, modern water tube boilers take water cooling wall as the main heating surface of evaporation.

Advantage

1. The membrane water cooling wall has the most thorough protective effect on the furnace wall. Therefore, the furnace wall only needs insulation material instead of refractory material, which greatly reduces the thickness and weight of the furnace wall, simplifies the structure of the furnace wall and reduces the total weight of the boiler.

2. The membrane water wall also has good air tightness and can adapt to the requirements of positive pressure combustion on the boiler. It is not easy to slag formation and air leakage. It can reduce the heat loss of exhaust smoke and improve the thermal efficiency of the boiler.

3. The components can be welded by the manufacturer, and the installation is quick and convenient.

4. The boiler with membrane wall structure is convenient and simple in maintenance, and the service life of the boiler can be greatly improved.
