<p>A wood burning stove comprises a fire chamber of which the upper part is constituted as a heat exchanger. A primary air supply is provided as is a secondary air supply, the secondary air supply permitting air to be mixed with the gaseous products of combustion to support complete combustion of those gaseous products. Both air supplies have dampers, the damper of the secondary air supply being automatic and opening as the damper of the primary air supply is closed. The secondary air supply comprises an inlet manifold interconnecting a plurality of tubular elements which form a fire supporting grate, the tubular elements leading the secondary air beyond the fire to a region in which mixing of that air with the gaseous products of combustion is effected, secondary air passing through the tubular elements being preheated by the burning fuel supported on the grate.</p> |
