To treat gas collected in a temperature region less than a catalyst activation temperature inside a furnace in a continuous kiln used in a burning process in manufacturing a plasma display panel.
The continuous kiln in which a work piece is heated according to a predetermined temperature profile while being transported in the furnace is equipped with a discharge box 31 for collecting binder-removed gas generated from the work piece, a catalyst unit 41 for performing decomposition treatment of the collected binder-removed gas in the furnace, and a discharge pipe 33 extending in the furnace from the discharge box 31 toward the catalyst unit 41. The catalyst unit 41 is further on the downstream side than the discharge box 31 in the transporting direction, and is provided in a furnace region in which the temperature is the temperature for decomposition by the catalyst of the binder-removed gas generated from the work piece is activated or higher.
