Abstract

PURPOSE: To achieve high efficiency of heat recovery by buring and decomposing exhaust gas from a painting drying furnace and re-cycling into the drying furnace for the re-use of heating the combustion air in a burner.
CONSTITUTION: A fixed amount of exhaust gas, including organic solvent evaporated from the coating on materials to be dried, is sent to a catalytic combustion device 7 through an exhaust duct 50 by a collecting fan 37 set over a drying furnace A, to be burned and decomposed. Furthermore, high temperature exhaust gas is circulated in a transport duct 10 arranged at the bottom in the furnace, and is separated to flow through heat exchangers 81, 82, 83, 84 set near heating devices 21, 22, 23, 24 paralleled in the lower part of the drying furnace A, to be discharged outside. At this time, the heating of burner combustion air absorbed through flowers 401, 402, 403, 404 takes place by heat exchange at each exchanger, improviding combustion efficiency of each burner 31, 32, 33, 34.
