Abstract

The invention relates to a fireplace comprising a firebox (1) and a grate (3) provided with apertures (10) for supplying primary air into the firebox (1) comprising a wall assembly (2) provided with at least two horizontally extending arrays of apertures (100, 200, 300) for supplying secondary air into the firebox. In order to be able to burn firewood in the fireplace so that the emissions, in particular carbon monoxide and nitric oxide emissions, simultaneously remain very low, the distance between said at least two arrays of apertures (100, 200, 300) in the vertical direction ranges between 30 and 150 mm, and both arrays of apertures comprise apertures (100a, 100b, 100c and 200a, 200b, 200c) arranged to supply secondary air in a point-like manner substantially in the horizontal direction converging at an angle gamma = 30 to 80 degrees against one another so that the point-like jets from the apertures hit one another. <IMAGE>
