High Efficient Carbon Steel Boiler Membrane Wall Tube Fire / Water Tube Structure industrial plant

Product Introduce

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 is the main heating part of the boiler, it consists of several rows of steel tubes, distributed around the boiler furnace.Its internal flow of water or steam, the external acceptance of the boiler furnace flame heat.It mainly absorbs the radiant heat of high temperature combustion products in the furnace, in which the working medium rises and evaporates when heated.

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
