Heat Exchange Membrane Water Wall for Water Tube Boiler ASME Certificated

Product Description And Types

Membrane water wall panels is air leaktight construction which combined by tubes and fins.It's usually installed on the inner of boiler chamber,mainly uesd to absorbe radition heat from flame and high temperature gas.It' a evaporation heat surface of modern boiler and also as a basis past for water circulation loop in boiler,which can cooling and protect furnace wall.

HDB manufacture membrane water wall panels include below 3 types:

1.Steel flat and bare tubes are weld to a raw,which is meterial saving and low costing ,can meed all variety requiments of pitch.

2.Welding fin tubes in a row,this type only need short leadtime,can meeting rush product delivery.

3.Bare tubes burnt and welding,the intertube fins are formed by the melting and filling of welding wires.It's mainly used in short pitch wall panels.

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.
