Note
The water wall is usually vertically installed on the inner wall of the furnace. Water or steam flows inside it, while the outside absorbs heat from the furnace fire and high-temperature flue gas. Its main functions include:
1.Heat Absorption: It absorbs the radiant heat from high-temperature flames or flue gas in the furnace, and the water inside is heated into saturated steam.
2.Furnace Wall Protection: By absorbing the radiant heat in the furnace, it protects the furnace wall from damage caused by high temperatures.
3.Improving Combustion Conditions: It reduces furnace leakage, improves combustion conditions, and enhances the thermal efficiency of the boiler.
4.Reducing Steel Consumption: The excellent heat transfer performance can lower the steel consumption of the boiler and reduce the boiler cost.
Product Description:
A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler. They serve a two fold purpose here in that they capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler. And they also help keep the refractory cool.This prevents spalling of the refractory.

Usually laid vertically on the inner surface of the furnace wall, it is mainly used to absorb the radiant heat from the flame and high-temperature flue gas in the furnace.It is the main type of evaporative heating surface of modern boiler and also the basic part of water circulation loop of boiler.As a combination of cooling and protective furnace wall.
The water-cooling walls were originally designed not to be heated, but to cool the furnace so that it would not be damaged at high temperatures.Later, as a result of its good heat exchange function, gradually replaced the drum to become the main heating parts of the boiler.
An evaporative heating surface composed of many parallel pipes is arranged on the inner wall of the boiler furnace.The role of the water wall is to absorb the radiant heat of the high temperature flame or flue gas in the furnace, generate steam or hot water in the pipe, reduce the temperature of the furnace wall, and protect the furnace wall.In the large capacity boiler, the flame temperature is very high and the intensity of thermal radiation is very high.The boiler contains 40 to 50 percent or more of the heat absorbed by the water wall.With the exception of a few small capacity boilers, modern water tube boilers use water cooling walls as the main evaporative heating surface.
