Title:
COATING DRYING FURNACE
Document Type and Number:
Japanese Patent JP3133659
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the generation of a reaction product deteriorating a coating film by attaching a bypass air passage for bypassing a gas delivered from a radiating means and mixing the gas with a gas passing through a circulating passage in the furnace and using a combustion heater also as a furnace heating means.
SOLUTION: A coated material 2 placed on a truck 3a is passed successively through a heating zone 1a and first and second heat insulating zones 1b and 1c by a conveyor 3 in a coating drying furnace 1. The heating zone 1a is provided with a radiating panel 7 for the material 2 in addition to the air suction chamber 5a and exhaust port 6a. In this case, a bypass air passage 21 is branched from the air passage part in the radiation circulating air passage 20 for introducing a gas PA delivered from the internal air passage of the radiating panel 7 into a combustion heater 19a. Namely, a high-temp. gas PA" is bypassed from the circulating air passage 20 and supplied to the circulating air passage 9a to heat a gas RA' to be returned to the furnace 1a from the passage 9a, and the heater 19 is used also as a furnace heating means Ha.
