ABSTRACT:
An air-fuel ratio programmable control method for a fuel burner installation, and a fuel burner installation adapted to operate by the control method. In the method, an error (Ep) is determined by subtraction of an input (Po) representative of the existing firing rate and an input (Pn) representative of the required firing rate; depending on whether Ep is positive or negative, fuel and air supplies to the burner are modulated in either air-led or fuel-led manner, respectively, to set the firing rate to the desired value (Pn); in addition, the error (Ep) is compared to a predetermined breakpoint (Xp) so that if Ep exceeds Xp fuel and air supplies to the burner can be modulated simultaneously for fast control action.
