Abstract (en)

[origin: WO2006000367A1] 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 ?, 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 ?=1. According to the inventive method for adjusting the excess air coefficient, said maximum temperature T<SUB>max</SUB> is determined, whereupon the desired setpoint value ?<SUB>hy</SUB> of the excess air coefficient is adjusted and the associated setpoint temperature T<SUB>soll</SUB> is measured. A characteristic curve which represents the correlation between the respective air mass flow rates and the setpoint temperatures at the setpoint value ?<SUB>hy</SUB> of 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 T<SUB>soll</SUB> at 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.
