Patent ID: 7922481

Claim:
A method for setting operating parameters on a firing device, in particular on a gas burner with a fan, an actual temperature produced by the firing device being dependent upon a value of a specific air ratio and having a maximum operating temperature when the value of the specific air ratio equals 1, the method comprising: controlling a pre-determined air mass flow; establishing a gas mass flow corresponding to the maximum temperature; defining a desired value for a hygienic air ratio for a desired hygienic combustion; controlling the desired hygienic combustion by changing the pre-determined air mass flow by the desired value for the hygienic air ratio for the desired hygienic combustion while maintaining a constant supply of the gas mass flow; measuring desired temperatures at different air mass flows corresponding to a desired air ratio, establishing a characteristic line which represents a correlation between the air mass flows and the desired temperatures at the desired air ratio; regulating the actual temperature to a first desired temperature corresponding to a specific burner load at a first air mass flow using said characteristic line; and regulating the actual temperature to a second desired temperature different than the first desired temperature at a second air mass flow different than the first air mass flow using said characteristic line when a load change occurs.
