Product Description

Bare tube water wall panel export product positive tolerance premium quality with low cost

 

PRODUCT DESCRIPTION

 

1 Tube panels are fabricated using premium grade raw materials in carbon steel or alloy steel as per the customers' requirement.
2 Layers of tube panels involving multi radius bends, overlapping each other to be accommodated in lesser space for ultimate efficiency.
3 Compact size and leak proof assembly.
4 Widely used in water tube and waste heat recovery boilers, tube panels can be customized as per the specifications and drawings of customers.
5 Smelting units, power stations and sugar plants are the common buyers of this product.

 

SOLUTION TO CORROSION PROBLEMS IN LOWER FURNACE

 

1 An innovative, engineering solution for solving corrosion or erosion/corrosion problems experienced by the waterwall is to apply an overlay of a corrosionresistant alloy to carbon steel waterwalls on site using automatic welding machines.
2 The GMA W overlay machine, which is fully automatic, deposits weld beads in a vertical down mode starting typically from the membrane and then moving to the tube section following a preprograrnrned weld bead sequence to achieve a uniform coverage of the waterwall (i.e., membranes and tubes) in a boiler.
3 Each weld bead is overlapped by subsequent weld bead to insure a full coverage with no missing spots.
4 The thickness of the overlay applied to the watelwall in field is typically 1.78 mm (0.070") minimum. 
5 For overlay welding of the waterwall in the field, it is a common practice to use many welding machines, for example, 10 or more, at the same time in the boiler to complete the project during a maintenance shutdown. 
6 A modem machine can deliver a welding "speed" of approximately 0.14 to 0.19 m2 (1.5 to 2.0 fY) per hour. 
7 Thus, with 10 machines, a total area of about 16.7 to 22.3 m 2 (180 to 240 fY) of the waterwall can be overlaid over a 12-hour shift. A waterwall area of about 280 m 2 (about 3000 fY) can be routinely overlaid in seven days using a two 12-hour-shift-per-day schedule. 
8 When the waterwall is damaged beyond repair on site, the damaged section can be removed and replaced with shop-fabricated overlay panels. 
9 Panels of sizes up to 1.2 m (4 ft) wide and 12 m (40 ft) long can be readily handled in the shop. 
10 Construction of an overlay panel consists of fabricating a panel of steel tubes and membranes, which is then followed by overlay welding of the panel on a stand using essentially the same techniques as field overlay. 

 

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.
