1. Boiler furnace and outside wall apply membrane wall resulting in well sealing, no leakage and well combustion. In the mean time, the weight is reduced because of no refractory materials (not necessary).
2. Applying double-drum D-type and water-tube structure; Compact-structure and small volume; Package outgoing, saving installation cost.
3. Large furnace, sufficient heating surface; complete fuel burning, well heat transferring.
4. Large steam and water volume can well adapt load fluctuation.
5. Fully automatic control, well-known brands of electric elements guarantee fine quality, convenient and flexible operation.
6. Well-known Europe burners, super quality valve without leakage.
7. Multi-level pressure and water level protection, guaranteeing boiler safe running.
