Heat insulation boiler spare part Water Wall Panels for power plant boiler seamless steel tubes
Boiler spare part Water Wall Panels Product Introduction
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
Membrane Water Wall Panel Product
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.
