ZOZEN SHL Series of steam & hot water boilers are coal fired bulk water-tube boilers with dual cylinders (drums) and work in a natural circulation.Horizontal dual cylinders and water-tube wall form a vertical well-type furnace. At the rear of boiler, there is an economizer and air preheater. If necessary, it is available to set up a superheater inside the furnace. The grate links are made from scale-type fire bars. The mode of gearbox is stepless speed control. It is bulk type for site assembly and masonry.

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.
6. It is natural water circulation. Each heating area has independent downcomer for water supply to make sure the whole water circulation is safe.
7. Large furnace design
- The flue gas can stay longer in the furnace to make the ash and combustible gas burn abundantly. So that the heat efficiency can be raised.
- In the large furnace, the flue gas rises slowly, which can reduce the ash quantity and get a very low emission.
