1. A system for cleaning a burner and confining fuel in solid-fuel boilers comprising a circular plate of the burner associated with a combustion chamber, the circular plate having a center and a circular perimeter, the circular plate being mobile and rotating on a central axis of the plate;
a fuel supply device that supplies solid fuel from a storage hopper to the center of the plate through an intake line using controlled/automated dosing; and
multiple ash-discharging devices fixed around the perimeter of the circular plate comprising multiple curved blades, each curved blade comprising a central head having a central axis and two curved wings extending radially out from the central head, the curved blade rotating on the central axis to continuously reach any position between a tangential one in which the multiple curved blades are arranged on the perimeter of the plate and a radial in which the blades are arranged on the entire width of the plate so that the blades can clean by sweeping the ashes deposited that occupy a crown (C) of any width between a minimum that corresponds to the edge of the plate and a maximum (Cm) which corresponds with the entire width of the plate.
