High Efficiency Boiler Membrane Wall for Energy Saving



What are the four types of membrane?
Tissue membranes are thin sheets of cells that cover and line body surfaces;
there are four main types— mucous, serous, cutaneous, and synovial.​



What material are boilers made of?
alloy steel
Modern boilers are made of alloy steel to withstand high pressures and
extremely high temperatures. Most conventional steam boilers are classed as
either fire-tube or watertube types. In the fire-tube type, the water
surrounds the steel tubes through which hot gases from the furnace flow.



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.

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.
