Abstract (en)

[origin: EP1243857A1] A method and device for adjusting the air ratio of a gaseous fuel/air mixture for operating a burner (18) comprises measuring the mass flow (7) and the Wobbe (viscosity) index of the fuel (5), measuring the mass flow of the air (13) and controlling a mass flow on the basis of these values to give the predetermined value of lambda. An Independent claim is also included for a device for the above method having flow sensors and a data unit to regulate the fuel flow though a dosing valve.
