Abstract
A burner system for controlling the gas/air mixture of a burner has a sensor providing a signal dependent on the pressures in gas and air lines supplying the burner. A summing device receives a signal based on the air flow rate and the signal from the sensor, and provides a regulating signal controlling the setting of a gas regulating valve regulating the flow of gas in the gas line.
Claims4
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).
