Abstract
A combustion apparatus for the burning of solid fuel using a plurality of secondary combustion zones is disclosed. The combustion apparatus includes primary and secondary air inlets, an inclined hearth and a unique second air source which washes up a window in the combustion apparatus creating a floating flame effect and rendering the window self-cleaning. A series of baffles define a secondary combustion pathway which optimizes secondary combustion of exhaust gasses and particulate matter. Coaxial rear and top direct venting apparatus are also disclosed. The combustion apparatus provided combusts a wide range of solid fuel at a high level of efficiency.
