Steam Boiler Water Wall Tubes Made of Carbon Steel in ASME/GB Standard

Power plant Condensing gas boiler Water Wall tubes high temperature TUV certification manufacturer​

Product Description

Pressure loss caused by wall tubes (or risers, evaporator tubes) of a natural circulation boiler should be at low level because of the natural circulation principle. Thus, vertically installed riser tubes in natural circulation boilers have a larger diameter than riser tubes in forced circulation boilers. All natural circulation boilers must have an upwards-rising arrangement of wall tubes because of the circulation principle. There are variations on how sharp the rise is: In conservative vertical furnace boilers the wall tubes are placed in a straight vertical direction . In corner tube (Eckrohr) boilers the wall tubes are arranged as slightly rising or horizontal wall-tube banks.

The advantages of membrane type water wall

(1) Guarantee the sealing of the furnace wall,reducing air leakage in combustion chamber .
(2) Water Cooling in combustion chamber, so that in the case of enhanced combustion is helpful to prevent coking.
(3) Heat storage capacity is small, the combustion chamber heats up fast, faster cooling, can shorten the boiler to startup and reduce the furnace cooling time.
(4) Appropriatly using the pipe wall, thereby significantly reducing the boiler frame load, is advantageous for the suspension.
(5) Compared with the light tube, improve the heat absorption capacity of the pipe.
(6) Improve the degree of the boiler parts of combination, conveniently reduce the workload of the installation.
