Manufacturing and Design Technique Features


1.The key processing technology of steel and tube cutting, plate rolling and drum drilling, etc adopts advanced CNC machining process, which can decrease the assembly stress and prolong the working life.

2.Steel tube cutting, end polishing, rust cleaning and bending are processed by advanced CNC.

3.The whole production line is automatic.

4.We adopts advanced automatic unionmelt welding process to ensure the welding quality. All the vertical and circular welding seams will be inspected by 100% X-ray detection.

5.Tubes and flanges are welded together by robot.

7.Chain grate combustion furnace with reasonable arch structure and air distribution can fit different fuel.


Control and Safety System


1.The control and safety systems are interlocked in an electric control cabinet.

2. Alarm system

- Sound-light alarm of high and super-high steam pressure;

- Sound-light alarm of high and lowe water limit level;

- Sound-light alarm of pressure loss in the water pumps;

- More safety devices are designed and connected with the electric control cabinet (ECC).
