Burner air mass flow for efficient gas combustion

In industrial combustion processes, the aim is to achieve the highest possible combustion efficiency, currently intensified by the sharp rise in energy costs. To achieve this, the mass ratio of air (oxygen) and fuel must be matched to each other - the "air number" lambda must remain under control.

Whereas in gas combustion there is usually a precise gas mass flow measurement, there is usually no solution for air mass flow measurement (fixed damper position without measuring device) or only an inaccurate solution (classic dynamic pressure probes). Alternatively, very expensive, space-consuming solutions are used today (venturi).

Precise air mass flow recording: Luftmeister solves this metrologically challenging task with the help of the laboratory-calibrated precision measuring sections in conjunction with the Luftmeister MS 55. The following picture shows alternately the measuring solution and the Luftmeister calibration laboratory, where this measuring solution is calibrated and adjusted with high precision. The advantages of the Luftmeister solution are manifold:

• Optimal control of mass ratios brings the most efficient gas combustion, thanks to high-precision air-mass flow detection.
• Highest accuracies are achieved even with short inlet sections (confined spaces are often the reason for curved air lines). Particularly with large cross-sections, expensive conversions or space-consuming air lines can be dispensed with.
• Compared to the frequently used Venturi measuring points, an at least equal accuracy is achieved at significantly lower costs.
