Abstract

See full text

An apparatus that employs dual air ducts is described for balancing the return air flow between forward and reverse fan directions in a direct-fired lumber kiln. As freshly heated air enters the kiln, this system forces the air to pass through the stacks of lumber at least once before returning to be reheated. The disclosed apparatus and methods enable more efficient use of energy, reduce drying time and improve the uniformity and precision of the lumber drying process.
