Abstract:
A mixing chamber assembly for mixing burner output with kiln return air. A first vertical duct that receives kiln return air from the first return duct when the kiln is operated in a first mode and receives kiln return air from the second return duct when the kiln is operated in a second mode. A second vertical duct in fluid communication with the first vertical duct so that the kiln return air enters the first vertical duct, travels upward, and changes direction to then travel downward in the second vertical duct to pass downward into a dispersion chamber to provide downward movement of the kiln return air. The dispersion chamber having a hot duct discharge to convey burner output laterally above a delay table surface. The downward movement of the kiln return air colliding with the burner output to provide mixing of the kiln return air with the burner output.

Claim (Index 19):
A system for circulating heated air to treat lumber, the system comprising:\n a structure having a floor, a roof above the floor, a first end and a second end with at least the first end having an opening so that lumber may be moved into and out of the structure so that stacks of spaced lumber may be treated, a wall along a first side extending from the first end to the second end, and a wall along a second side opposite from the first side a direct fired burner which provides heat to an air blending chamber which provides heated air to the structure though use of a supply duct and a blower; a set of at least one circulating fan located on in a center wall located above a horizontal fan deck and below the roof; set of dampers and a pair of return ducts to allow for kiln return air to be drawn from the first side of the structure relative to the center wall when the at least one circulating fan is causing a pressure gradient to force air through the stacks of spaced lumber from the second side to the first side; and from the second side of the structure relative to the center wall when the at least one circulating fan is causing a pressure gradient to force air through the stacks of spaced lumber from the first side to the second side; both return duct feeding kiln return into a first section of a vertically integrated dual return assembly and flowing in a first direction before crossing over into a second section of the vertically integrated dual return assembly and proceeding in a second direction, opposite of the first direction, the kiln return air entering into a dispersion chamber with a delay table that receives a flow of burner output gas from a burner hot duct discharge oriented perpendicular to the flow of the kiln return air entering into the dispersion chamber, and the kiln return air and burner output gas at least partially mixing before entering an air balancing chamber and traversing the air balancing chamber to enter a suction side of a blower and returning to the structure through a supply duct.
