Methods for improved atmosphere control through secondary gas pressure wave firing

摘要

Methods of firing ware in a furnace. At least one stack of ware is positioned in a ware space of a furnace. The stack of ware comprises a plurality of ware articles arranged such that at least laterally adjacent ware articles are spaced apart. The at least one stack of ware is heated in the ware space of the furnace. At least one gas is introduced into the ware space on a first side of the at least one stack of ware as the stack is heated. A flow condition of the at least one gas is adjusted to create a pressure differential within the furnace across at least a portion of the ware space such that at least some of the at least one gas flows through the at least one stack of ware.

1. A method for firing ware in a furnace, the method comprising:
positioning at least one stack of ware in a ware space of a furnace, the stack of ware comprising a plurality of ware articles arranged such that at least laterally adjacent ware articles are spaced apart; heating the at least one stack of ware in the ware space of the furnace; introducing a first gas flow into the ware space on a first side of the at least one stack of ware as the stack is heated; introducing a second gas flow into the ware space on a second side of the at least one stack of ware as the stack is heated; and adjusting a flow condition of at least one of the first and second gas flows to create a pressure differential within the furnace across at least a portion of the ware space such that at least some of the first or second gas flows through the at least one stack of ware, wherein the first gas flow introduced on the first side of the stack has a first flow rate FR1, the second gas flow introduced on the second side of the stack has a second flow rate FR2, and FR1≠FR2.
