Abstract: A bio-mass burner having a continuous feed on demand to a first combustion chamber that contains a hollow grate structure. The novel method of operation includes the use of at least one venturi tube which is in fluid communication with the hollow grate structure to establish an air flow into a second combustion chamber. Primary air to support combustion in the first chamber is supplied to the underside of the grate structure. Secondary air to support combustion in the second chamber is supplied through the hollow grate structure and then to the venturi tube in a sufficiently tortuous path through the first combustion chamber to insure that the air is superheated at the outlet of the venturi tube. A baffle arrangement in the first combustion chamber directs the fuel product toward the grate structure and assists in preventing any unburned gases from being ejected into the atmosphere.
