Abstract:
A burner system for providing a gas flow and a combustion-air flow to a burner, including:a) a first line (10) carrying the gas flow; b) a gas regulating valve (11) in the first line (10) receiving a regulating signal (24) and varying the gas flow rate in the first line responsive to the regulating signal (24); c) a second line (14) carrying the combustion air flow; d) an evaluating device (28) operatively connected to sense the combustion air flow and to provide an auxiliary signal (27) depending on the combustion air flow; e) a sensor (19) connected between the first line (10) carrying the gas flow and a second line (14) carrying the combustion-air flow, and providing a signal (22) dependent on the gas pressure and the combustion air pressure; f) a summing device (26) receiving the signal (22) of the sensor (19) and the auxiliary signal (27) and providing a sum signal (30) depending on the sensor signal (22) and the auxiliary signal; and g) a regulating unit (23) receiving the sum signal (30) and generating the regulating signal (24) for the gas regulating valve (11).
