Product Description

Lloyd's Certification Biomass Boiler Heating Surface Pin-Type Membrane Wall Submerged-Arc Welding

 

 

Membrane Water Wall Description


Membrane water wall is an air-tight structure consisting of pipes and fins.The advantages are less air leakage in furnace; can use pipe-laying wall, less load on steel structure and lower cost of boiler; easy to use suspension structure and improve thermal expansion system, suitable for large-scale mechanized production, high assembly rate, low heat storage capacity and shorten star-up and shutdown time. The disadvantage is that the manufacturing process is complex. Membrane water wall is often used in large capacity, high temperature and high pressure boilers.

 

The heating surface arranged on the inner wall of the furnace is mainly cooled by water, which is called the water wall. It is the main evaporation heating surface of power station boiler. The main functions of the water wall are :

(1) absorbing the radiant heat in the furnace, heating the water into saturated steam;

(2) protect the furnace wall, simplify the structure of the furnace wall, reduce the weight of the furnace wall, which is mainly due to the absorption of radiant heat in the furnace wall water wall, so that the temperature of the furnace wall is reduced;

(3) the absorption of heat in the furnace, the flue gas cooled to the temperature allowed by the furnace exit, which is beneficial to reduce the slagging in the furnace and prevent the slagging in the furnace exit;

(4) The water wall absorbs radiant heat at high temperature in the furnace and has good heat transfer effect, so it can reduce the boiler steel consumption and boiler cost.

 

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.

Note

 

1 Control of weld penetration to satisfy mechanical and heat transfer requirements Control of the deformation to acceptable tolerances.
2 Panels 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?
3 Can existing shop handling procedures be used as-is without adding excessive controls that will add cost and schedule.
4 The 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.
