Reliable Boiler Membrane Wall Products for Uninterrupted Operations
Does a boiler need to be insulated?
Boiler Insulation | What To Know | Firwin Corp
Loss of heat means loss of energy, which leads to higher expenses.
If boiler pipes are left exposed as they carry heated fluid, more
energy is needed to keep the boiler functioning at the optimal
level. Boiler pipe insulation will prevent the loss of thermal
energy and maintain low energy costs.
What is difference between cladding and insulation?
1. Insulation is used to prevent the heat loss (in HE, for example)
or to prevent galvanic corrosion. *Coating is used to prevent
external corrosion. 2. 2. Cladding uses a layer of expensive
metal say CRA to protect the inexpensive metal that tends to
corrode much easier. so, it reduces the overall cost.
Reliable Boiler Membrane Wall Products for Uninterrupted Operations
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.

| Installation location | Around the boiler combustion chamber |
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.
