which rise from the charge in the inner annulus 28 through the space between the annuli 27, 28 and into the burning fuel on the grate, which gases are largely composed of products of partial combustion of the fuel charge in the inner annulus 28, whereby the intensity of the combustion in the combustion chamber or fire-pot of the stove is favorably influenced, and economy in fuel secured.

Surrounding. the back and two, sides of the casing is 'afseries of [spaced jverticalitubular cOnduit's BI. Thesehave their lower ends communicated with a chamber 32 which is coexr;

The damper openingf36 in the partition 22 is provided for; creating adirect draft for the stove as-when starting afire therein. As seen, the products ofcomb'ustio n finally escape through the chimney collar ,39. ;In this way a relatively small amount of fuel expenditure secures a large radiation of;
