OD 600mm Boiler Membrane Wall , Anti Wear Wall Water Panel

Customized OD30-600mm Water Wall Panels for Boiler, Anti Wear Water Water Panel

Product Introduce: Boiler Membrane Water Wall Panel

Membrane water cooling wall refers to the water cooling wall composed of air-tight pipe screen welded by flat steel and pipe.The membrane water cooling wall can guarantee the good tightness of the furnace chamber, significantly reduce the air leakage coefficient of the furnace chamber for the negative pressure boiler, and improve the combustion condition in the furnace.It can increase the effective radiation heating area and save steel consumption.

Water Wall Panels are used in modern day Boilers to reduce heat loss due to their gas tight nature and reduce insulation costs. We fabricate Water Wall Panels using automatic Fin to tubes welding machines and large Tube Panel Benders to achieve desired shape of panels which can have Stub Welded to Headers. We supply Panels with integrated manhole openings in the panels.

Advantages

(1) the protective effect of membrane water cooling wall on the furnace wall is the most complete, so the furnace wall only needs insulation materials, rather than refractory materials, so that the thickness and weight of the furnace wall are greatly reduced, simplify the structure of the furnace wall, reduce the total weight of the boiler.

(2) membrane water wall also has good air tightness, can adapt to the requirements of positive pressure combustion on the boiler, not easy to slag formation, less air leakage, reduce the heat loss of smoke exhaust, improve the boiler thermal efficiency.

(3) it can be welded into components by the manufacturer for quick and convenient installation.

(4) the use of membrane wall structure of the boiler, simple maintenance, boiler service life can be greatly improved.

Features

1. Strength calculation report with applied materials information;
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;
4. Hydraulic test report: ensure the standard working pressure and safety

Product types

According to the type of structure, there are three main types of light tube type, membrane type and thorn tube type.The water wall of optical tube is composed of a whole row of seamless steel tubes, which has the simplest structure.Membrane type water wall is a lot of water wall fins rolled good tube spot welding each other together, so as to become a sealed composite heating surface, not only can improve the air tightness of the furnace, reduce air leakage, but also can better protect the furnace wall, so that the furnace wall weight reduction, structure simplification;Barbed tube water wall is in the water wall pipe welding a lot of long 20 ~ 25mm, diameter of 6 ~ 12mm pin, and then apply chrome ore refractory plastic, in order to reduce the water wall of the part of the heat absorption, improve the temperature of the combustion zone, suitable for fuel fire especially difficult occasions or some liquid slag furnace.Press to arrange a place, have type of add a wall and lie between wall type (namely double sided heating) water cooling wall two kinds.The former is mostly embedded in the inner wall of the furnace wall and absorbs heat on one side.The latter is mostly installed in the middle of the large boiler furnace, the whole furnace is separated into two independent parts, heating on both sides.
