Abstract
A wood burning stove incorporates a catalytic cell for reducing exhaust emissions from the stove. A pair of heat shields are spaced from opposing surfaces of a combustor to exchange thermal radiation with the combustor. The combustor is oriented at an acute angle to enhance the combustor life. One of the heat shields also functions as a deflector for deflecting exhaust toward the combustor. A secondary air unit supplies secondary air to the vicinity of the combustor. A dynamic grate assembly is employed to prevent under firing of the firebox.
