Corrosion Resistant Steel Boiler Membrane Water Wall Panels For Thermal Power

General description

The full name is water wall tube, old name is water-cooled wall,also called riser. Usually laid vertically on the inner wall of the furnace, they are used to absorb the radiant heat by the flame and high temperature flue gas.They are the main form of heating surfaces for the various modern boilers, also the basic parts of water circulation circuit. For they have the functions of cooling and protecting the furnace wall, so called water wall panels.

Water wall panels are the main heating surface of boilers, composed of numbers of rows of steel tubes, arranged around the boiler corner. Inside is the flowing water or steam, and the outside accepts the heat of the flame in the furnace of the boiler, mainly absorbing the radiation heat of the high temperature combustion products in the furnace. The working fluid rises in it and evaporates by heat.

Strong points of membrane water wall

(1) Ensure the sealing of furnace wall and reduce air leakage in combustion chamber.

(2)The realization of full water cooling in combustion chamber is beneficial to prevent coking under the condition of intensified combustion.

(3)The cooling time of start-up and shutdown of boilers can be shortened because of its small heat storage capacity, fast temperature rise and fast cooling in combustion chamber.

(4)Pipe-laying furnace wall is suitable, which greatly reduces the load of boiler frame and it is convenient for suspension and lifting.

(5)Compared with the bare tube type, the heat absorption capacity of the tube is improved.

(6)It improves the per-assembly degree of boiler components, facilitates and reduces the installation workload.

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.
