I. General introduction of SZL D type high efficiency water tube biomass fired steam  boiler

II. Advantages of SZL D type high efficiency water tube biomass fired steam  boiler

1. National Scientific and Technological Progress Second Prize

2. Singapore New Product Expo Golden Lion Award

3. With special fuel hopper and fuel discharge device.  

4.Three pass boiler. The smoke go through three phase, making the boiler have  higher heat transfer efficiency and lower smoke temperature emissed. 

5.The hearth is designed with a cyclone reburning chamber, which makes the boiler energy saving, high  combustion efficiency and environmental friendly.  

6.Special air distribution design. 

7.The hearth has large volume and strong fuel adaptability, it can use various biomasses  as the fuel.The big size furnace can  be well adapted to biomass's  feature of high flame.

The size of some most common biomass fuel:

(1).Biomass pellets:≤Φ10×30 mm

(2).Wood chips:≤100×50×50 mm

(3).Sawdust:≤20×20×10 mm

8.The arch is specially designed accordign to the fuel. 

9.Design of  preventing fouling, slagging and corrosion of heating area. 

10. It has a double-drum offset hearth (D-type layout) with furnace in the right side of the boiler and two drums in the left side of the boiler,  the structure is very compact.
