Abstract:

A continuous heating furnace (200) is provided with: a conveyer (210) which is endlessly stretched and conveys an object to be fired; a furnace body (212) which surrounds part or all of the conveyer and forms a firing space; and a roller (214) which supports part of the conveyer in the furnace body. The continuous heating furnace (200) is further provided with: one or more closed type gas heaters each comprising an inflow hole through which fuel gas flows into a heater body, a combustion chamber in which the fuel gas is burned, a lead-through part through which exhaust gas is led, a radiation surface which is heated by the exhaust gas flowing through the lead-through part or the burning in the combustion chamber and transfers radiant heat to the object to be fired, and an exhaust hole through which the exhaust gas that has heated the radiation surface is discharged to the outside of the heater body, and each being disposed in the furnace body; and an exhaust pipe (216) which communicates with the exhaust hole of the closed type gas heater and to which the exhaust gas is led. The exhaust pipe enables heat exchange between the exhaust gas flowing through the exhaust pipe and the roller.
