In combustion of gasified fuel by gasifying a low quality fuel and combusting the gasified fuel in a combustor, combustion of gasified fuel is controlled by sampling the gasified fuel at a constant flow rate at the upstream side of the combustor, combusting the sampled gasified fuel, detecting an overall energy level of sensible heat and heating value possessed per unit weight of the gasified fuel on the basis of the combustion temperature of the sampled gasified fuel, and controlling the flow rate of gasified fuel to be led to the combustor in accordance with a fluctuation in the detected overall energy level. Unstable combustion due to a fluctuation in the heating value of the gasified fuel and blow-out due to deficiency of the heating value can be prevented.

A method for controlling the combustion of gasified fuel in a process for combustion of gasified fuel by gasifying a low quality fuel and combusting the resulting gasified fuel in a combustor, which comprises continuously sampling a gasified fuel at a constant flow rate at the upstream side of the combustor, combusting the sampled gasified fuel, thereby detecting an overall energy level of sensible heat and heating value possessed per unit weight of the gasified fuel on the basis of a combustion temperature of the sampled gasified fuel, controlling an actual flow rate of the gasified fuel to the combustor in accordance with fluctuations in the detected overall energy level and charging an auxiliary fuel into the combustor, when the detected overall energy level becomes lower than the necessary minimum value for maintaining combustion in the combustor.
