A method for commissioning a biomass heating system for combusting fuel in the form of pellets and/or wood chips, the biomass heating system comprising a boiler with a combustion chamber, a blower and a control device with a memory and a display, the method comprising the following steps: Determining (S2) whether the biomass heating system is initialized for the first time, wherein if the biomass heating system is not initialized for the first time, the method is terminated, and if the biomass heating system is initialized for the first time, the method is continued with the following step: Setting a plurality of heat generation parameters (S5) comprising at least the following parameters: a boiler type parameter defining at least a working range of the blower; a material parameter defining the characteristics of the fuel(s) to be combusted.

A rotating grate for a biomass heating system is disclosed, the grate comprising: at least one rotating grate element; at least one bearing axle, by means of which the rotating grate element is rotatably mounted; at least one cleaning device attached to one of the rotating grate elements, wherein the cleaning device comprises a mass element movable relative to the rotating grate element; wherein the cleaning device is arranged in such a way that, upon rotation of the rotating grate element, an acceleration movement of the mass element is initiated so that the cleaning device exerts a knocking effect on the rotating grate element in order to clean the rotating grate element.

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.
