Specifications

 

 

With the horizontal type, wetback and three-backhaul structure design, the boiler has a compact structure, reasonable layout and good-looking appearance.

With the finned tube economizer arrangement on the tail, boiler has a compact shape for the smaller boiler room.

The application of such enhancement components of heat transfer as the corrugated furnace and spirally corrugated tubes not only intensifies the turbulent heat transfer of the high temperature flue gas but also relieves the thermal expansion of the furnace body effectively.

The low-level combustion chamber design is adopted to reserve a large water level safety space to minimize the risk of water shortage accidents.

Adopt international famous brand burner, best quality and safety.

Adopt best fire-proof and insulation materials, lower the boiler surface temperature, improve the thermal efficiency.
