The Ecotherm Three-Pass-Wet-Back System means optimal combustion and minimum energy loss. It protects the environment by saving energy and operating costs.
1. Flame tube of large diameter guarantees perfect combustion. Combustion chamber of generous dimension to suit the various types of fuel.
2. Man-hole and several inspection-holes for fast and easy inspection of boilers water side.
3. "Wet-back" boiler design with water cooled reversing chamber and wet back flame tube bottom - avoiding sensible refractories.
4. Sight holes for flame observation on rear side of flame tube.
5. Safety flap to avoid damages in event of a fuel deflagration.
6. Easy cleaning of flue gas tubes by hinged door at the reversing chamber in front and cleaning holes in the rear reversing chamber and the flue-gas connection.
7. Highest exploitation of fuel by the flue-gas tubes of 2nd and 3rd pass. Efficiency of combustion up to 92 %.
8. Sight glass for flame observation on front side.
9. Excentric position of flame tube effects natural circulation of boiler water.
10. Steady capacity and pressure even at fluctuating loads due sufficient water and steam space.
11. High grade insulation minimises heat loss.
12. Steam drier, large evaporation surface and large steam space guarantee dry saturated steam.
