An introduced-air-flow-rate SA is determined by adding an adjusted value A given from an oxygen density controlling system to a required-air-reference-flow-rate RA demanded by the charging amount of pellets The introduced-air-flow-rate is controlled where the required-air-reference-flow-rate RA is the feed forward value Thus, it the charging amount of the pellet is varied, since the introduced-air-flow-rate SA is determined by the adjusted value A and the required-air-reference-flow-rate RA varied in response thereto, the control response can be quickened without decrease of the stability. Further, at the abnormality of the oxygen sensor, as the adjusted value A is controlled to be zero, the required-air-reference-flow-rate RA is decided of itself as the introduced-air-flow-rate SA
