Abstract: A catalytic combustion type exhaust gas processing device wherein noxious/smelly components contained in exhaust gases are deodorized and purified through sequential oxidative decomposition by at least one catalyst layer composed of platinum and/or palladium catalyst and a copper-cerium catalyst comprising chemically active species of copper and cerium in a compounded form. The device can be applied effectively to a drying furnace, for example, used in a coating for automobile use.

Abstract: A method of heating a drying furnace for use in hot air-circulating type coating drying in which a hot air is supplied, under circulation, to the inside of the furnace thereby heating and drying coated articles, wherein heating for the furnace is conducted through a direct heating type hot air-circulating path in which the air inside of the furnace sucked from a return duct is heated directly by a combustion gas from a burner and supplied under circulation from a supply duct again to the inside of the furnace while conducting a step of increasing the temperature by pre-heating the inside of the furnace, whereas heating for the furnace is conducted through an indirect heating type hot air circulating path in which the air inside of the furnace sucked from the return duct is heated in a heat exchanger and then supplied, under circulation, through the supply duct again to the inside of the furnace while conducting a coating drying step when the temperature inside of the furnace reaches a predetermined temperatur
