ABSTRACT:
A furnace (A) defines a combustion chamber (10) in which a pair of burners (B) are mounted for oxidizing the fuel to heat the combustion chamber. An air blower (12) supplies air to the burners at a rate controlled by a rate control valve (18). A frequency modulated burner control system (C) controls the duty cycle of the burners, i.e. cyclically actuates the burner at a fixed burn rate and then deactuates them. The burner control system varies the actuation to deactuation ratio in each cycle to vary the thermal input to the combustion chamber. The burners provide two - stage combustion wherein a fuel rich mixture is partially oxidized in a first stage combustion area (44). Additional air which is thereafter introduced through air passages (50, 52) completes the combustion.
