ABSTRACT:
A stove (1) for the combustion of solid fuel (4), such as wood, a fire box within the stove forming the combustion chamber (2) for the fuel is provided with a hollow hood (20) extending over the combustion chamber. A primary air inlet (7) and channel provide a supply of air to the combustion chamber for primary combustion and a secondary air inlet (9) and channel provide a supply of air to the hollow hood (20). The hollow hood has a multiplicity of air exit apertures (32) distributed across the lower surface (25) of the hood to provide air for secondary combustion in the upper region of the fire box. A flue gas exit orifice (36) is provided in the hood, the orifice being defined by a hole in both the lower surface (25) and upper surface of the hood, the holes being connected by a wall or walls (37) with a plurality of apertures (39) therein. Air is thereby supplied to the flue gases (10) exiting through the orifice (36) enabling secondary combustion to occur in the orifice.
