PURPOSE: To suppress calorie fluctuation at a minimum limit by changing over devices to the other hand from one hand in accordance with necessity and performing control in the case of enabling both of flow rate control of convertor gas and flow rate control of coke oven gas to be performed and performing calorific value control of combustion of three kinds of gaseous mixtures.
CONSTITUTION: The calorific value control of combustion of a first gaseous mixture is performed by providing devices PI2, V2 for controlling the flow rate of B gas so that its flow rate is regulated to certain rate for the flow rate of a gaseous mixture, devices PI3, V3 for controlling the flow rate of C gas so that it is regulated to fixed flow rate and a device PI for controlling the flow rate of L gas so that calorie of the gaseous mixture is regulated to target value. Further devices PI1, V1 for controlling the flow rate of L gas so that its flow rate is regulated to fixed flow rate and a device P2 for controlling the flow rate of C gas so that the calorie of the gaseous mixture is regulated to target value are provided. The calorific value control of combustion of a second gaseous mixture is performed by changing over the devices PI3, V3 to the device P2 and changing over the device P1 to the devices P1, V1 respectively.
