<p>In a combustion apparatus for solid fuel, e.g. a door-fronted stove, at least one duct for the supply of combustion air leads to a combustion chamber (1). The duct or ducts (8a-8c) open out into the combustion chamber above the hearth, and spreader devices (9a-c, 10a-c, 11a-c) are used to cause the supplied combustion air to flow down towards the hearth. The spreader devices are preferably situated at different levels above the hearth and direct the air substantially towards the centre of the hearth, preferably with a turbulent air flow.</p> |
