Abstract:
Provided is a gasification furnace apparatus equipped with a source which supplies a drying gas having a low oxygen concentration and eliminates the necessity of a fuel.  The apparatus comprises: a coal pulverizer (1) in which coal is pulverized to produce dust coal; an air separator (3) in which air is separated into oxygen gas and nitrogen gas; and a gasification furnace (2) into which the dust coal, oxygen, and a gas are introduced to produce a product gas.  As the low-oxygen-concentration gas for drying the dust coal, use is made of air diluted with nitrogen supplied as excess nitrogen gas from the air separator (3).  The apparatus further includes, disposed therein, an air heater (5) which heats the low-oxygen-concentration gas to a temperature which renders drying possible.
