Patent number: 7922481Abstract: 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 Tmax is determined, whereupon the desired setpoint value ?hy of the excess air coefficient is adjusted and the associated setpoint temperature Tsoll is measured. A characteristic curve which represents the correlation between the respective air mass flow rates and the setpoint temperatures at the setpoint value ?hy 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 Tsoll at different predefined burner loads.Type: GrantFiled: June 20, 2005Date of Patent: April 12, 2011Assignee: EBM—Papst Landshut GmbHInventors: Martin Geiger, Ulrich Geiger, Rudolf Tungl
