Largest Pressure Part CO2 Welding Seamless Tube Boiler Membrane Water Wall


Product Introduction


The seamless tube boiler membrane water wall is main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end heat surface and proceed the heat exchange directly with the high temperature fume.


The membrane water wall is the main heating part of the boiler.It consists of several steel pipes and is distributed around the boiler.


Description:

Water wall panels are used in Waste Heat recovery boilers. We manufacture Water wall panels. These are fabricated out of carbon steel tubes to customers' drawings and specifications. Special care is taken for ovality and thinning at the bent portion, during fabrication.


We are manufacturing and supplying a comprehensive range of Waterwall Panels. The tubes offered by us are known to withstand a great internal pressure as a continual strip of fin material is wound spirally on the tube. These tubes are known to provide heat uniformly that result in an increased heat output.


The main function of water wall panels in boiler is to absorb the heat generated by high temperature flame or flue and to generate steam or hot water in tubes, hence to reduce the temperature in the chamber.


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


1Energy saving enviromental protection china supplier membrane water wall for CFB boiler are membrane walls that are made of tubes welded together with or without a strip of metal in between.
2These walls form the enclosure of the coal combustion chamber.
3Water 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.

Note


1Control of weld penetration to satisfy mechanical and heat transfer requirements Control of the deformation to acceptable tolerances.
2Panels routinely require straightening in the workshop after welding and heat treatment, the question to be answered is can the shop then meet the required dimensional tolerances for successful site installation?
3Can existing shop handling procedures be used as-is without adding excessive controls that will add cost and schedule.
4The importance of preheating and its maintenance through the welding process could cause a number of handling and shop processing issues that will substantially increase cost.
