Technical Features of mobile grate burner
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 (max 50%) 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 fan and one or two secondary combustion air fans upper the grate (depending on the output). 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.
