Abstract:
A kiln for drying at least one stack of lumber, the kiln comprising:a kiln chamber defining a chamber interior space capable of receiving at least the stack of lumber for drying;a furnace capable of providing heated air;a plenum in communication with the furnace so that the plenum is capable of receiving the heated air from the furnace;an air moving device capable of circulating air in the chamber interior space along a flow path;a plurality of elongate conduits in communication with the plenum, wherein each conduit:extends into at least a portion of the flow path,has opposite ends,defines a length that extends between the opposite ends and is generally perpendicular to the portion of the flow path into which the conduit extends,defines a plurality of outlets positioned along at least a section of the length of the conduit and proximate the flow path so that the conduit is capable of providing heated air from the plenum to the flow path via the outlets,defines a first cross-dimension that is generally perpendicular to the length of the conduit and parallel to the portion of the flow path into which the conduit extends, anddefines a second cross-dimension that is generally perpendicular to both the length of the conduit and the portion of the flow path into which the conduit extends, wherein the second cross-dimension is less than the first cross-dimension, whereby the conduit defines a low profile with respect to the portion of the flow path into which the conduit extends.
