Abstract

The invention relates to a fire grate for a burner for burning o solid fuel bodies, which fire grate (9) comprises an inside (10) with a supporting surface (11) intended for receiving fuel bodies, outlet holes (14) for combustion-supporting gas being arranged in said inside (10) in order to make possible supply of combustion-supporting gas to fuel bodies resting on the supporting surface (11). The inside (10) of the fire grate comprises two o more spaces (12), each of which being formed by a hollow (13) arranged in said inside (10) and each of which having at leas one outlet hole (14) for combustion-supporting gas arranged in the associated hollow. The invention also relates to a burne comprising such a fire grate.
