Boiler Waterwall Panel
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.
Our membrane water wall are manufactured with high grade raw
material and contemporary production equipment at our advanced
production unit. Various sizes, shapes and specifications, will
meet all the requirements of our clients . Further, cargoes are
delivered to the clients within lead time.

Advantages of Membrane Water Wall
1). To guarantee the leakproofness of furnace wall and reduce the
air leak of combustion chamber.
2). To achieve the full water cooling of combustion chamber, and
the boiler accessories membrane water wall is benefit to prevent
coking under the condition of supplemental firing.
3). The thermal storage capacity is small, the warming of
combustion chamber is fast and the cooling is also fast, which
could shorten the cooling time of boiler’s start and furnace shut
down.
4). It is good to adopt top supported water cooled wall and it
could reduce the load of boiler framework, which is benefit to
overhang.
5) Compared with the bare tubes, the membrane water wall improves
the heat absorption capacity of tubes.
6) The factory direct boiler membrane water wall could improve the
Preliminary combination degree of boiler parts and reduce the
installation workload.
Application
Boiler water walls are membrane walls that are made of tubes welded
together with or without a strip of metal in between. These walls
form the enclosure of the coal combustion chamber. Water wall tubes
are also referred to as the evaporator section; they contain water
mostly in liquid form which gradually evaporates as it rises in the
boiler.
Challenges
As the water wall tubes form a lining along the whole boiler, they
are submitted to a temperature gradient of 300 °C to 500 °C between
the bottom section of the boiler and its top. To facilitate
fitting, the panels in the boiler should preferably be made of
steel grades that do not require any post-weld heat treatment.
Vallourec supplies tubes for water walls in all grades, from carbon
steel to advanced low-alloy steel, with outside diameters ranging
from 31.8 mm to 63.5 mm.
