Abstract: A shuttle kiln (100) according to certain aspects includes at least one flue channel (124) and multiple flue risers (122) in fluid communication with the flue channel (124), and at least one shuttle (104) defining multiple exhaust shafts (140) arranged above the multiple flue risers (122), wherein an aggregate volume of a first exhaust shaft/riser pair (140-1, 122-1) differs from an aggregate volume of a second exhaust shaft/riser pair (140-2, 122-2). Such configuration at least partially compensates for different backpressures that would otherwise be experienced by flue gas exiting a shuttle kiln cavity (138) through different exhaust shafts (140), thereby improving uniformity of flue gas flow and reducing temperature variability within a kiln cavity (138).

Abstract: A shuttle kiln according to certain aspects includes at least one flue channel and multiple flue risers in fluid communication with the flue channel, and at least one shuttle defining multiple exhaust shafts arranged above the multiple flue risers, wherein at least one radiation blockers is arranged above outlet ports of the at least one shuttle. Such a configuration blocks line-of-sight radiant heat transfer between (i) heated surfaces above the shuttle within the kiln housing and (ii) outlet ports of the exhaust shafts, thereby enhancing radiant heat retention and reducing temperature variability within a kiln cavity of the shuttle kiln.
