Type “Marine” three-ways smoke boiler with water production for heating; Boiler shell in steel; Doors for internal inspections and boiler cleaning; Cast iron burner with mechanical feeding system; Cylindrical combustible feeding hopper with mechanical stirrer; Fire fighting system in the hopper; Variable speed screew for automatic feeding; Primary and secondary combustion air system; Voltage:  230 V up to 100 kW, 400 V from 130 kW up to 2000 kW.

Dry basement complete with mobile grate mechanical burner, equipped with cast iron bars resisting too high temperatures. The mobile grate feeding system allows the use of solide combustible materials such as wood chips, crushed wood waste, etc., with high humidity and thickness (about 15 mm). The horizontal movement of the grate avoids the forming of solid crusts in order to have the best combustion. The wide surface grate is completed with grate movement system, electric board for the grate movement device, sub-grate primary combustion air fans equipped with shutters for the regulation of the air and a secondary combustion air fan upper the grate. The mobile grate is inserted inside the steel dry basement, completely coated internally in the combustion area with bricks and refractory material; it is externally insulated and painted. The basement is equipped with an ash extractor system composed of extraction screw, gearbox for the movement of the screw and ash collection box.
