<P>PROBLEM TO BE SOLVED: To provide an industrial furnace apparatus that can save energy by suppressing an electric power consumption rate of oxygen-enriched air generated at a pressure fluctuation adsorption type oxygen enricher. <P>SOLUTION: An industrial furnace apparatus includes: a pressure fluctuation adsorption type oxygen enricher 1 whose body is composed of, in sequence from an upstream side of an airflow channel AR: a compressor C for supplying compressed air; a plurality of adsorption towers AT for adsorbing nitride gases in the compressed air; and a buffer tank BT for storing oxygen-enriched air generated at the adsorption tower AT; and an industrial furnace 2 in which the discharge pressure P1 of the compressor C is controlled so that the oxygen density of gas generated at the oxygen enricher 1 falls into a range of 28 to 60%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
