Abstract (en)
[origin: EP2682679A2] The method involves monitoring flow between fuel gas pipe (2) and combustion air pipe (14). A fuel gas-air ratio is leaned out until measured signal exceeds/falls limit value. A differential pressure sensor (4) detects presumably richer and leaner fuel gas-air ratios that are approached as target fuel gas-air ratio. A flow in direction of combustion air pipe and fuel gas pipe is detected in action presumed to lean fuel gas-air ratio of volumetric flow. The differential pressure sensor detects flow in direction of combustion air pipe for setting error and error signal.
