<p>The present invention relates to a grate for use in a burning device. The grate consists of two plates (2, 3) on top of each other, which are rotatable in relation to each other. Both plates comprise apertures such that by rotating the plates in relation to each other, the openings through both plates are made smaller or larger, and at least part of the apertures in at least one of the plates being arranged on the periphery of a circle. The apertures (6) arranged on the periphery of the circle are elongated so that they are longer in the direction of the periphery of the circle than in the radial direction of the circle.</p> |
