Regulating turbulent flows

A method for regulating a burner device, wherein the burner device includes a feed duct, a side duct branching from the feed duct, a bypass duct branching from the side duct, and a mass flow sensor arranged in the bypass duct, the method comprising:

• setting a first actuator to deliver a requested mass flow of a first fluid through the feed duct;
• measuring an actual mass flow of the first fluid through the bypass duct using the mass flow sensor;
• and
• adjusting a setpoint for a second actuator to modify a mass flow of the first fluid through the feed duct based at least in part on the measure actual mass flow of the first fluid through the bypass duct;
• generating a signal with a probe in an exhaust gas duct;
• transferring the signal from the probe to a λ regulator;
• determining a variable factor between the flow of a fuel through a fuel feed duct and the flow of a fluid through the feed duct as a function of the transferred signal;
• assigning a flow of a fuel through the fuel feed duct to a flow of a fluid through the feed duct on the basis of the variable factor determined.

A method for regulating a burner device having a feed duct with a regulator, a first actuator and a second actuator mounted in series in the feed duct, a mass flow sensor mounted in a bypass duct from a side duct off of the feed duct, the side duct including a first flow resistance element and a second flow resistance element, the bypass duct including a third flow resistance element mounted in series with the mass flow sensor within the bypass duct, the method comprising:

• requesting a flow of a fluid through the feed duct;
• adjusting a setting of the first actuator based on the requested flow;
• measuring an actual flow of the fluid through the bypass duct downstream of the third flow restriction element using the mass flow sensor;
• comparing the requested flow of the fluid through the feed duct to a corresponding flow of the fluid through the bypass duct;
• and
• controlling the second actuator as a function of the actual value of the flow of the fluid through the bypass duct and the corresponding flow of the fluid through the bypass duct;
• generating a signal with a probe in an exhaust gas duct;
• transferring the signal from the probe to a λ regulator;
• determining a variable factor between the flow of a fuel through a fuel feed duct and the flow of a fluid through the feed duct as a function of the transferred signal;
• assigning a flow of a fuel through the fuel feed duct to a flow of a fluid through the feed duct on the basis of the variable factor determined.
