Product introduction

Water Walls has bare tube Water Walls and membrane water walls.

Membrane water wall is made of flat steel and pipe tiles welded into the airtight tube composed of water wall.

The bare tube water wall is composed of a row of seamless steel tubes, the structure is the most simple; membrane water wall is a lot of rolling good water wall fins with spot welding welded together to make a sealed combination of heating surface, both Can improve the airtightness of the furnace, reduce the air leakage, but also protect the furnace wall, reduce the weight of furnace wall, simplify the structure.


 Pin water wall is consisted by many pins with length 20~25mm, diameter 6~12mm welded to water wall tube.And then apply chrome ore refractory plastic to reduce the amount of heat absorbed by the water wall, increase the temperature of the combustion zone, applying to the case where the fuel is particularly difficult to lignite or some liquid slagging furnace. According to the layout of, there are diaphragm-type and wall attached type (that is, double-sided heating) water wall. The former mostly embedded in the wall of the furnace wall, single-sided endothermic; the latter in most of the large boiler in the middle of the furnace, the entire furnace divided into two separate parts, double-sided heating.


Performance advantage

Our company has MAG welding film wall production line 3 (Gaomi 1, Jilin 2), equipment manufacturers are Harbin Hua Wei, CLP Huaqiang.

Gaomi plant -12 head welding torch, Jilin plant area - 20 torch (fight small row); 4 (big row).

Membrane water wall can improve the airtightness of the furnace, reduce the air leakage, but also protect the furnace wall, so that to reduce the weight of the furnace wall and simply structure. The furnace's flue gas with high temperature is not in direct contact with furnace wall to avoid slagging. Our company introduced advanced membrane water wall production line, and produce products with good quality with premium and efficient service which satisfy clients.
