Boiler bare tube with membrane bar at two sides export project single fin bar tube
Product information
1. The membrane wall is also called the membrane type water wall.
2. With a hose and flat steel welding of boiler furnace wall.
3. The size of each component according to the requirements of the whole loop pipe group welding and become, reoccupy welding seal between group and group when installation.
4. Make the furnace surrounded by a layer of the whole water wall closely surrounded by diaphragm.
Material composition
Characteristic
1. The membrane wall of the furnace wall of protection is the most complete instead of refractory material.
2. Make the wall thickness and weight are greatly reduced, simplify furnace wall structure, reduce the total
weight of boiler 's membrane water wall has good air tightness, able to meet the requirements of positive
pressure combustion of boiler, not easy slagging, less air leakage.
3. Reduce exhaust smoke heat loss, improve the boiler thermal efficiency; By manufacturing welded components factory, install quickly and easily.
