Abstract
The temperature generated by a firing apparatus, particularly a gas burner, depends on the mixing ratio between the quantity of air and the quantity of gas fed to the firing apparatus, characterized by the excess air coefficient λ, at a predefined burner load (air mass flow rate) in such a way that the temperature generated by the firing apparatus reaches a maximum when λ=1. According to the inventive method for adjusting the excess air coefficient, said maximum temperature Tis determined, whereupon the desired setpoint value λof the excess air coefficient is adjusted and the associated setpoint temperature Tis measured. A characteristic curve which represents the correlation between the respective air mass flow rates and the setpoint temperatures at the setpoint value λof the excess air coefficient and allows combustion to be regulated to an optimal hygienic state can be determined from said determined correlation between the setpoint temperatures Tat different predefined burner loads. The inventive firing apparatus is adapted to carry out said method and especially comprises a mass flow sensor in the air delivery zone as well as a temperature sensor in the effective range of the burner flame.
