Abstract
Stable operation of oxyfuel combustion boiler is ensured and amplification in likelihood of or downsizing of forced draft fan is attained. Upon change of commanded boiler load from start value to target value by target time, a feed amount of oxygen from oxygen producing device is regulated for attainment of oxygen concentration on entry side of the boiler body from reference value to attainment point or target entry-side oxygen concentration within entry-side oxygen concentration regulation range by target time. After attainment to attainment point, control is made to return entry-side oxygen concentration to reference value at return point. Airflow rate of forced draft fan is controlled with change rate smaller than change rate with which air flow rate of forced draft fan reaches target value by target time.
