A wood burning stove having a primary combustion chamber and a secondary chamber having a catalytic converter therein is disclosed. Primary air is introduced to said primary chamber and secondary air is introduced to said secondary chamber utilizing completely separate and independent control means, with the draft means for said primary and secondary air both being located below the fuel (wood) support level. Means are provided for preheating both the secondary air and the catalytic converter.

DETAILED DESCRIPTION What is claimed is: 1.
A stove comprising front, rear, top, bottom and side walls, a door on said front wall movable between closed and open positions to permit access to the stove interior, a substantially horizontal partition in said stove located intermediate said top and bottom walls, the space between said partition and said bottom wall defining a primary combustion chamber, support means located adjacent the bottom of said primary chamber for supporting the fuel to be burned therein, first draft means for controlling introduction of primary air to said primary chamber and being located adjacent the bottom of said primary chamber, said partition having two openings therein, a catalytic converter mounted on said partition in registry with one of said openings whereby all gases passing through said one opening pass through said converter, damper means movable between a first position normally completely covering said other opening and a second position wherein said other opening is unblocked, handle means operable from outside the stove to move said damper between said first and second positions, said handle means blocking opening movement of said door when said damper is in its said first position, whereby said door can be opened only when said damper has been moved to its said second position, second draft means for controlling the introduction of secondary air to said stove at a location adjacent said partition, said second draft means being located adjacent the bottom of said primary chamber, and an exhaust duct communicating with said stove at a location above said partition.
2.
In the stove of claim 1, said first and second draft means both being located below the level of said fuel support means.
3.
In the stove of claim 1, temperature sensing means located exteriorly of said stove for automatically controlling operation of said first draft means.
4.
In the stove of claim 1, sensing means for automatically controlling operation of said second draft means, said sensing means extending into said stove at a location adjacent said converter and being effective to sense the presence of unburned hydrocarbons or oxygen at said location, whereby secondary air is automatically introduced should sufficient unburned hydrocarbons or oxygen be present
