Abstract
A furnace adapted to burn wood chips and wood particles and including an inner cylinder adapted to be positioned in horizontal relation and including a primary combustion area. A funnel assembly is provided for supporting a quantity of wood particles and for funneling the wood particles into the primary combustion area of the inner cylinder. A second cylinder is also provided, the second cylinder having a length greater than that of the inner cylinder and having one end which surrounds the inner cylinder such that the inner cylinder and the second cylinder define an air space therebetween. The other end of the second cylinder defines a secondary combustion area where the combustion gases from the primary combustion area are mixed with secondary air.
