ABSTRACT:
The invention relates to a device for adjusting the mixture of oxidation agent/fuel in the feeding pipe (22) of a burner. Said device comprises means (32, 12) for changing the composition of the oxidation agent/fuel mixture and a measuring instrument (2) for detecting the condition of the oxidation agent/fuel mixture and a circuit (28) for controlling said means (32, 12) for changing the composition on the basis of the condition detected by the measuring instrument. The invention is characterized in that the measuring instrument detects the condition of at least one partial mixture of the oxidation agent/fuel mixture via the viscosity or a function therefore before the combustion and that it is located upstream, in terms of the direction of flow, of the means (32, 12) for changing the composition. The invention is also characterized in that the measuring instrument controls the composition in accordance with a function of the detected viscosity by means of the circuit for controlling the means (32, 12) or that it is located downstream of the means (32, 12) for changing the composition and that it controls the composition of the oxidation agent/fuel mixture by means of the circuit for controlling the means (32, 12).
