Heat Recovery Boiler Spare Parts Water Wall Tubes Stainless Steel / Alloy
Product Description
The water cooling wall is the main heating part of the boiler.It is the internal flow of water or steam, outside the heat from the boiler furnace.It mainly absorbs the radiation heat of the high-temperature combustion products in the furnace, in which the working medium moves upward and is heated to evaporate.
Specification
| Name | Membrane water panel |
| Material | Carbon steel,Alloy,Stainless steel |
| Tube size | Φ38 - 76 mm, Customize |
| Standard | ISO , ASME |
| Model | Studded |
| Application | Istallable around the boiler combustion chamber |
Functions
1. The water cooling wall is the high-temperature radiant heat absorbed by the fuel chamber flame, which makes the water entering the water cooling wall evaporate into saturated steam.
2. Protect the furnace wall. The water cooling wall is laid on all sides to separate the combustion chamber from the furnace wall and prevent the furnace wall from being burnt out.
3. Simplify the furnace wall structure for easy installation, and pay attention to the anti-friction and explosion-proof network of the boiler.
4. The water-cooled wall tube can absorb radiation heat well, and its evaporation intensity is 4 times that of the convection tube bundle. Appropriately increasing the water-cooled wall tube in the furnace will reduce the number of convection and heating surface.
The water-cooling screen is used to distinguish the early light-pipe water-cooling wall, the water-cooling wall of the early boiler is a pipe vertical around the furnace, and the water-cooling wall is surrounded by thick furnace wall. The water-cooling wall pipe of the current boiler has fins on both sides and two adjacent pipe fins are connected together to form a water-cooling screen, which is distributed around the furnace.
Certification
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.
