Abstract
Various embodiments include a method for regulating a burner appliance comprising a combustion chamber, an air supply duct with an actuator to adjust the air supply, and a fuel supply duct with a fuel actuator to adjust the fuel supply. The method comprises: determining the value of the air supply V L; determining the value of an air ratio λ; providing an individual scalar fuel parameter h; calculating the power output P_ist of the appliance based on the air supply V L, the air ratio λ, and the individual scalar fuel parameter h using P_ist=h/λ·V L; and regulating the burner appliance with the fuel actuator and the air actuator until the actual value reaches the target value.
Claims15
A method for regulating a burner appliance comprising a combustion chamber, an air supply duct leading to the combustion chamber with an air actuator configured to adjust a value of an air supply V′_L through the air supply duct, and a fuel supply duct leading to the combustion chamber with a fuel actuator configured to adjust a value of a fuel supply V′_B through the fuel supply duct, the method comprising:
- determining the value of the air supply V′_L;
- determining a value of the air ratio λ;
- providing an individual scalar fuel parameter h;
- calculating an actual value of a power output P_ist of the burner appliance based on the value of the air supply V′_L, the value of the air ratio λ, and the individual scalar fuel parameter h using P_ist=h/λ·V′_L;
- and
- regulating the burner appliance with the fuel actuator and the air actuator based on the actual value P_ist and a target value P_soll of the power output until the actual value reaches the target value.
A non-transitory computer-readable memory storage medium storing a set of commands for implementation by a regulating and/or controlling and/or monitoring facility for a burner appliance comprising a combustion chamber, a fuel supply duct leading to the combustion chamber with a fuel actuator configured to adjust a value of a fuel supply V′_B through the fuel supply duct, and an air supply duct leading to the combustion chamber with an air actuator configured to adjust a value of an air supply V′_L through the air supply duct, the set of commands causing the regulating and/or controlling and/or monitoring facility to:
- determine the value of the air supply V′_L;
- determine a value of the air ratio λ;
- provide an individual scalar fuel parameter h;
- calculate an actual value P_ist of a power output of the burner appliance from the value of the air supply V′_L, the value of the air ratio λ, and the individual scalar fuel parameter h in accordance with P_ist=h/λ·V′_L;
- and
- regulate the burner appliance with the fuel actuator and the air actuator based on the actual value P_ist of the power output and a target value P_soll of the power output of the burner appliance until the actual value reaches the target value.
