CONTINUOUS HEATING FURNACE
摘要:
A continuous heating furnace includes one or a plurality of closed type gas heaters (110) each having a combustion chamber in which a fuel gas is combusted, a guide section that guides an exhaust gas generated by combustion in the combustion chamber, a first radiation surface extending in a direction perpendicular to a conveyance direction of a baking object, heated by combustion in the combustion chamber and heat of the exhaust gas passing through the guide section and configured to transfers radiant heat to the baking object, and an exhaust hole through which that discharges the exhaust gas that heated the first radiation surface is discharged, and disposed in a furnace main body, and one or a plurality of exhaust heat transfer units (214) juxtaposed with the closed type gas heater in the conveyance direction of the baking object in the furnace main body and each having a second radiation surface (214a) that communicates with the exhaust hole of the closed type gas heater and heated by the exhaust gas to transfer the radiant heat to the baking object, and a heat transfer acceleration unit (216) that accelerates heat transfer from the exhaust gas to the second radiation surface at one end (214b) side or the other end (214c) side in a direction perpendicular to the conveyance direction of the second radiation surface.
