SA-210 ASME Standard High Efficient Heat Exchange Boiler Part Water Wall Panels For Utility/Power Station Plant
Introduction
HDB provides replacement wall panels, burner openings, inspection ports and doors for utility and industrial boilers. Recently completed projects include rear and sidewall replacement as part of a complete reheater replacement and the studded burner throat with bifurcated tubes pictured to the right. Inspection ports, camera ports, and access doors of any brand are also available.
Product Description
Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the combustion chamber. Water 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.
Usually following water or steam are in the water wall panels to absorb heat from combustion chamer which can get the purpose of heat exchange.
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.
Functions
1. The water wall absorbs the high temperature radiant heat of the flame in the fuel chamber, so that the water entering the water wall evaporates into saturated steam.
2. Protect the furnace wall. The water cooling wall is laid around to separate the combustion chamber from the furnace wall, prevent the furnace wall from being burnt out, and prevent the coking of the furnace wall and the harm of coke residue to the furnace wall.
3. simplify the structure of the furnace wall, easy to install.
4.water wall tube can absorb radiant heat very well, its evaporation heat intensity is four times the convection tube bundle, appropriate in the furnace to increase the water wall tube, will reduce the number of convection heating surface.

Additional
| 1 | Water wall panels are used in Waste Heat recovery boilers. |
| 2 | We manufacture Water wall panels,these are fabricated out of carbon steel tubes to customers' drawings and specifications. |
| 3 | Special care is taken for ovality and thinning at the bent portion,during fabrication. |
| 4 | We are manufacturing and supplying a comprehensive range of Waterwall Panels. |
| 5 | 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. |
| 6 | These tubes are known to provide heat uniformly that result in an increased heat output. |
| 7 | 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. |
Application
| 1 | Energy 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. |
| 2 | These walls form the enclosure of the coal combustion chamber. |
| 3 | Water 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
| 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. |
