Zusammenfassung:	Provided is a gasification furnace apparatus equipped with a supply source of low-oxygen-concentration drying gas that does not require fuel. A coal pulverizer (1) that produces pulverized coal by pulverizing coal, an air separator (3) that separates air into oxygen gas and nitrogen gas, and a gasification furnace (2) that produces product gas by introducing thereinto the pulverized coal, oxygen, and gas, are included. By receiving a supply of excess nitrogen gas from the air separator (3), the air diluted with nitrogen is used as a source of low-oxygen-concentration gas for drying the pulverized coal, and an air heater (5) that heats the source of low-oxygen-concentration gas to a temperature at which drying can be performed is provided.
