Abstract

PURPOSE:To improve controllability, by providing a means to control fuel consumption at the minimum, while satisfying nonoxidated combustion by avoiding oxidation caused by excess air of a device to control combustion which controls the temperature in a heating furnace. CONSTITUTION:In the primary processor 11, the detected value of air flow rate 'Fa' is input, and the result of process is output to a low selector 12. The low selector 12 compares the output of a result with a temperature master signal 'Mt', and it selects the lower one to output it. In the secondary processor 13, the detected value 'Fa' is input, and the result of process is output to a high selector 14. The high selector 14 compares the output of a result with the selected output by the lower selector 12, and it feeds the higher one into a fuel flow rate controller 5 as the setting value of fuel flow rate 'Ff'. In the tertiary processor 15, the detected value of fuel flow rate 'Ff' is input, and the result of process is output to a low selector 16, which compares the output with the output from a multiplier 10 and the lower one is fed into an air flow rate controller 9 as the setting value of air flow rate 'FA'.
