DZl series coal fired boiler, the capacity scope is 1T/H-80T/H.
1. Reasonable heat surface and burning device, heat efficiency is 4%~5% higher than national standard.
2. Reasonable flue speed design, heating surface without scattered ash and noabration. Under the condition of no sootblowing, the boilers can work full load, high efficiently and safely in long term.
3. The big and tall boiler furnace can be easily designed according to the different fuel to improve the burning rate of fuel and remove black smoke.
4. All single return design and injected circulation design for the hot water boilers the medium speed in return of heate sureface is higher than national standard.
5. Adopt big and high strength grate, add rolling device for big grate which improve the boilers' safety and lessen the leaked coal and adjust burning conveniently.
6. Scoot idiomatically separated at the exit of boiler furnace which can reduce dust content and lessen abrasion of back heat surface.
7. Closed scoot cleaning avoid the second pullution and save time and labor.
8. Big water volume benefits for power-off protection, high ability suitable for load waving.
