Shuttle kiln for firing ceramic porous bodies

摘要

The invention provides a shuttle kiln that can fire ceramic porous bodies containing organic binders in a shorter period of time than in conventional methods without occurring breaks due to a temperature difference between the inside and the outside. The shuttle kiln of the invention is suited for firing of ceramic porous bodies containing organic binders. It includes a gas suction path 4 that suctions in-furnace gas and discharges it via an afterburner 5 and a circulation path 7 that suctions the in-furnace gas to the furnace outside to burn organic binder gas and then returns it into the furnace.
