Energy Saving Boiler Parts Water Wall Panels For Power Station , ASME Standard

Product Description

Water wall panels usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling and protection of the furnace wall, so the name.

The water wall was originally designed not to be heated, but to cool the furnace from high temperature damage.Later, because of its good heat exchange function, it gradually replaced the steam drum as the main heating part of the boiler.

The evaporative heating surface, which is laid on the inner wall of boiler chamber and consists of many parallel pipes.The function of water wall is to absorb the radiant heat of high temperature flame or flue gas in the furnace chamber, generate steam or hot water in the pipe, and reduce the temperature of the furnace wall to protect the furnace wall.In a large capacity boiler, the flame temperature in the furnace is very high, the intensity of heat radiation is very large.Forty to fifty percent or more of the heat in the boiler is absorbed by the water wall.Except for a few small capacity boilers, modern water tube boilers take water cooling wall as the main heating surface of evaporation.

Specification

Modern boilers use water-cooled wall panels to reduce heat loss due to air tightness and reduce insulation costs.We use automatic finned pipe welding machine and large pipe bending machine to make water-cooled wall plate to achieve the desired shape of the panel, can have short welding head.We provide panel integrated manhole openings in the panel.

The main function of boiler water wall board is to absorb the heat generated by high temperature flame or flue and to produce steam or hot water in the pipe, thus reducing the temperature in the box.

Advantage

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.
