Abstract (en)
[origin: EP0939280A2] Heat storing fireplace comprising a firebox (2) provided with a grate (1) and a combustion space (3) above it, side channels (4,6) on both sides of the firebox and combustion space, leading to a chimney flue, heat storing material (5) placed above the combustion space, throat apertures (11,12) opening from the combustion space below the heat storing material for passing the combustion gases into the side channels, and a circulation channel (7) disposed around the heat storing material for passing hot gases around it. The circulation channel (7) forms a combustion gas channel surrounding the heat storing material (5) by its sides and top. In addition, the fireplace is provided with at least one flow controller (8, 9, 10) for directing the combustion gases asymmetrically into the side channels (4,6) so as to produce a circulating flow in a certain direction in the circulation channel (7). <IMAGE>
