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.

摘要： The invention provides a tunnel kiln for firing ceramic porous bodies which can fire ceramic porous bodies containing organic binders in a shorter period of time than in conventional methods without producing breaks or requiring nitrogen gas. The tunnel kiln includes a preheating zone 1, a firing zone 2, and a cooling zone 3 and fires the ceramic porous bodies loaded on a carriage 7 by driving it in a furnace. A heat storage regenerative burner 10 is used as means of heating the firing zone 2 so that low-oxygen-concentration exhaust gas discharged from the heat storage regenerative burner 10 may be returned to an exhaust gas return line 14 and supplied into the preheating zone 1. The exhaust gas return line 14 may be provided with a combustion device 17 that reduces the oxygen concentration by consuming oxygen contained in the exhaust gas.
