China Supplier Carbon Steel Membrane Water Wall Panels radiant heat

Carbon Steel Membrane Water Wall Panels Functions

1. Protect the furnace wall and reduce the erosion and damage of high temperature smoke and slag in the furnace to the furnace wall.
2. After installing water wall, the temperature of inner wall and flue gas temperature in furnace are greatly reduced, which can effectively prevent slag forming on furnace wall and heating surface, and reduce thickness and weight of furnace wall.
3. Modern large boiler, the use of furnace wall and water-cooled wall tube together to form a pipe-type or tube on the furnace wall, that is, the use of water-cooled wall tube suspended furnace wall.
4. The high temperature flame in the furnace conducts heat to the water-wall tube, mainly by radiation.
The radiative heat transfer intensity is proportional to the fourth power of the absolute gas temperature.
5. Because the gas temperature in the furnace is very high, so, the water wall tube in the furnace to absorb radiation heat transfer is very strong, is the main boiler evaporation heating surface.
6. For high pressure and ultra-high pressure boilers, radiant superheater is usually arranged on the top of the furnace;
7. For the dc boiler, part of the preheating heating surface (equivalent to economizer) and overheating heating surface (equivalent to superheater) are often arranged in the water wall;
8. While the supercritical dc boiler, because there is no evaporation heating surface, the water wall is only used to heat water and superheated steam.

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.

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.
