Painted Seamless Waterwall Panel Heat Exchanger Boiler Spare Parts High Efficient

Product Description

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.

Specification

Advantages

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

2.realize full water cooling of the combustion chamber, which is helpful to prevent coke formation in the case of intensified combustion.

3. small capacity of heat storage, fast heating of combustion chamber and rapid cooling, can shorten the cooling time of boiler start and stop.

4.it is appropriate to use pipe furnace wall, which greatly reduces the load of boiler frame and is convenient for suspension.

5.compared with the optical tube, the heat absorption capacity of the tube is improved.

6.the pre-combination degree of boiler components is improved, which is convenient and reduces the installation workload.
