A burner throat is described which is located between a producer and a burner. The burner throat includes a return gas line drawing hot combusted gases from the burner to the burner throat through an annular chamber surrounding the inlet portion of the burner throat. The burner throat also includes an out-of-line fan discharging an air stream vertically in the inlet portion of the burner throat to create a suction chamber. The burner is multichambered and includes secondary air inlet means for providing excess oxygen for producer gas combustion in an excess of oxygen. A portion of the burner is enclosed in a tunnel having an open end and a fluid flow. The fluid flow transmits heat from the burner through a first damper in the tunnel, and into a large fan enclosed within a fan room; the fan room has a supplemental heat source and second dampers. The fan has a plenum at its discharge side for receiving a heated discharge fluid flow from the fan to distribute to grain bins; the plenum includes a temperature sensing probe operationally connected to a temperature control means. The temperature control means simultaneously adjusts the first and second dampers and heat generation means to achieve a desired temperature for the heated discharge fluid flow in the plenum.
