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 method for firing a green honeycomb body and for manufacturing a cordierite honeycomb body. The honeycomb body is heated from an initial kiln temperature to a first kiln temperature that is from about 300° C. to 400° C., at an oxygen concentration greater than 16%. The honeycomb body is heated to a second kiln temperature that is from about 600° C. to 700° C. at a second heating rate of greater than 125° C./hr. The honeycomb body is heated to a third kiln temperature that is from about 800° C. to 900° C. at a third heating rate that is less than or equal to the second heating rate. The honeycomb body is heated to a fourth kiln temperature that is from about 1300° C. to 1450° C. at a fourth heating rate that is less than or equal to the third heating rate.
