Shuttle kiln exhaust configuration

A shuttle kiln, comprising:

• a kiln housing comprising a flue channel and a plurality of flue risers in fluidic communication with the flue channel, the plurality of flue risers comprising a first flue riser defining a first riser volume and configured to be arranged below a first exhaust shaft of a shuttle when the shuttle is positioned within the kiln housing, and a second flue riser defining a second riser volume that differs from the first riser volume, the second flue riser configured to be arranged below a second exhaust shaft of the shuttle when the shuttle is positioned within the kiln housing;
• and
• when the shuttle is positioned within the kiln housing, the first flue riser is separated from the first exhaust shaft by a first entrainment gap and the second flue riser is separated from the second exhaust shaft by a second entrainment gap that differs in size from the first entrainment gap.

A shuttle kiln, comprising:

• at least one shuttle configured to be removably positioned within a kiln housing, the at least one shuttle defining a plurality of exhaust shafts comprising a first exhaust shaft defining a first shaft volume and a second exhaust shaft defining a second shaft volume that differs from the first shaft volume, the first exhaust shaft configured to be arranged above a first flue riser of the kiln housing and separated therefrom by a first entrainment gap when the at least one shuttle is positioned within the kiln housing, the second exhaust shaft configured to be arranged above a second flue riser of the kiln housing and separated therefrom by a second entrainment gap that differs in size from the first entrainment gap when the at least one shuttle is positioned within the kiln housing.
