Abstract

PURPOSE: To retain completely burning state without stopping combustion in any combustion state by clamping the combustion supply amount at a specified lower limit value in low combustion state of heating furnace and supplying air amount sufficiently.
CONSTITUTION: In a device for automatically controlling the temperature of a combustion heating furnace FUR having a thermocontrol meter TIC-01, a fuel flow rate control meter FIC-02, an air flow rate control meter FIC-03, fuel and air flow rate control valves FCV-02 and FCV-03 controlled by the control meters, respectively, there is provided a low limiter FX-02 for retaining the valve opening of the valve FCV-02 constant by clamping the output of the meter FIC-02 at predetermined lower limit value when the output of the meter FIC-02 becomes less than predetermined lower limit value. There are also provided a function generator FY-04 for producing predetermined output signal responsive to the output of the meter TIC-01 and an adder FY-03 for adding the set value of the meter FIC-03 to the output of the generator FY-04 to apply the added output to the meter FIC-03 as a set value.
