Method for regulating a gas/air mixture

The method involves detecting the pressure difference between air and gas supply (5,6) by measuring device (7) in mixing device (3) at high sampling rate. The variability in measured values of differential pressure is determined. The low-pass filtering of the measured values is performed. The contro...

Zusammenfassung:	The method involves detecting the pressure difference between air and gas supply (5,6) by measuring device (7) in mixing device (3) at high sampling rate. The variability in measured values of differential pressure is determined. The low-pass filtering of the measured values is performed. The control of gas valve (8) is performed, such that pressure difference is compensated to zero. The control variables such as position of the gas valve or the minimum speed of the blower (1) are associated, when the reference value is exceeded by a threshold value.
