A method is disclosed for temperature control in a heating furnace including a step of regulating the emissivity of the flame in the heating furnace. This regulation is accomplished by adjusting the soot content of the flame. The soot content is changed by introducing auxiliary gaseous fuel, i.e., hydrocarbonaceous material, in addition to the main gaseous fuel, into the heating furnace. A heating furnace temperature control apparatus for carrying out this method is also disclosed.
