US 5,105,797 A · Solid fuel burning stove

Abstract

A solid fuel burning stove is provided and includes a housing within which a combustion chamber is located. The combustion chamber receives combustion air via an adjustable inlet formed through a channel member running along the base of the housing. The channel member defines a combustion air duct which communicates with a combustion air intake in the rear wall of the housing. Combustion air is drawn into the stove via the air intake and is forced through the combustion air duct by a fan. The combustion air passes through the adjustable inlet into the combustion chamber. A fire box is located within the combustion chamber above the adjustable inlet and holds the solid fuel to be combusted. Hot flue gases heat air flowing through a plurality of heat exchange tubes passing through the combustion chamber. The heated air flowing through the heat exchange tubes is directed into the room in which the stove is located via a plurality of vents in the front wall of the housing. The hot flue gases are then discharged from the stove via an exhaust in the rear of the stove. A hopper is also located within the housing and provides solid fuel to a delivery system which automatically replenishes the solid fuel in the fire box.

Dependent claims

A solid fuel burning stove comprising:

a housing having combustion air inlet means, combustion air outlet means, ambient air inlet means and heated air outlet means;
a combustion chamber within said housing communicating with said combustion air inlet means via controllable inlet means to permit the rate of combustion air flow into said combustion chamber to be varied, said combustion chamber communicating with said combustion air outlet means to permit combustion gasses to exit said housing;
a fuel perforated receptacle for holding solid fuel within said combustion chamber and overlying said controllable inlet means, means forming an enclosure between said fuel receptacle and said controllable inlet means whereby the supply of air through said perforated receptacle can be controlled;
and
a plurality of heat exchange tubes passing through the combustion chamber, said tubes receiving air to be heated via said ambient air inlet means and discharging heated air to said heated air outlet means.
