SYSTEM FOR CLEANING THE BURNER AND CONFINING FUEL IN SOLID-FUEL BOILERS

摘要

System for cleaning the burner and confining fuel in solid-fuel boilers of the type that consist of one plate, one supply device, at least one ash discharging device. The plate is mobile and has means to rotate with respect to the supply device and/or to each ash discharging device; each ash discharging device is fixed and has at least one blade with means to guide it at will on the plate occupying at least part of its perimeter. The blades of each ash discharging device are increased in height and occupy the entire perimeter of the plate, all of them delimiting, in conjunction with the plate and in an initial position where they act as side slats, a perimetrally closed container to confine a larger quantity of solid fuel on the plate without varying its size.

主权项

1. A system for cleaning the burner and confining fuel in solid-fuel boilers of the type that consist of a plate of the burner associated with the combustion chamber; a fuel supply device that supplies solid fuel from a storage hopper to the centre of the plate through an intake line using controlled/automated dosing; and, at least, one ash discharging device associated with a collector on which said ashes overflow from the perimeter of the plate; wherein
the plate is mobile and has means to rotate on a theoretical axis with respect to the supply device and/or to the ash discharging device; and each ash-discharging device is fixed and has at least one blade with means to guide it at will on the plate rotating on a theoretical axis to continuously reach any position between a tangential one in which the 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.
