Half-finished Product

Apart from H-type fin economizers, the water wall sub plant mainly manufactures membrane water wall tube panels of boiler furnaces, ceiling and enclosure membrane tube panels, as well as membrane wall components assembled with headers. The annual production capacity has reached 2300MW. The production area is 12000 square meters, the maximum crane span is 24 meters, and the maximum lifting capacity is 20 tons.

Main Equipment and Processing Capability

Membrane Wall Production Line:

The workshop is equipped with the most advanced membrane wall production lines. The tube panels are integrally welded together, and 12 welding heads simultaneously perform the gas-shielded welding from top and bottom, thereby protecting the tube panels from being deformed. The production lines comprise flat steel finishing equipment, panel assembly frames and 12 double-sided automatic MAG welding machines (made in the U.S.). The maximum width of tube panels capable of being welded is 3.2m, the length of tube panels is 16m and the tube diameter ranges from 32-76mm.

12-head MPM Automatic Welding Machine

Straight tube butt welding machine:
Hot-wire TIG welding machine (made in Canada), capable of welding tubes having a diameter ranging from 32-76mm and a wall thickness less than or equal to12.7mm.

Vertical water wall panel bending machine:
The bending machine is capable of bending tube panels having a maximum width of 2m, a minimum radius of 240mm and a bending angle less than or equal to 180 degrees.

Ф1200×4000 Huff Heating Furnace:
The Huff heating furnace is capable of integrally relieving the stress of the welded seams in corners of the headers assembled by using tube panels by performing the heat treatment.
The annual yield of the water wall sub plant exceeds 2600MW, able to manufacture water wall and wall enclosure components of 600MW boilers.

Main Machining Equipment and Processing Capacity
