Abstract: The invention relates to a control means for gas burners. Control means for gas burners are used for supplying a gas flow and a combustion air flow to a burner. In this procedure, the gas flow is adjustable in dependence on the combustion air pressure. In the case of known control means, pressure measurement is effected by means of a diaphragm, i.e. pneumatically. This pneumatic pressure measurement restricts the scope of application of known control means. In the case of the control means according to the invention, there is provided a sensor (16) which generates an electric or electronic signal 19 which is used for adjusting the gas valve 11 (FIG. 1).

Abstract: The invention relates to a regulating system for a gas burner. Regulating systems for gas burners are used for guiding a gas flow and a combustion air flow to the burner. The gas flow can be regulated depending on combustion air pressure. Pressure is measured in known regulating devices with the aid of a membrane, that is pneumatically. The pneumatic pressure measurement limits the scope of application of known regulating devices. In the invention regulating device, a sensor (16) is arranged between a first line (10) guiding a gas flow and a second line (12) guiding the combustion air flow, an electric or electronic signal (19) being generated by the sensor that is used to regulate the gas valve (11).

Abstract: The invention relates to a control method for gas burners for providing a gas-air mixture. A signal of a sensor is used for adapting the gas-air mixture to different gas qualities. According to the invention, the signal of the sensor is used for adapting the gas-air mixtures to different gas qualities at certain points in time only. This renders the control independent of aging processes of the sensor.

Abstract: A burner control system for controlling gas flow to a burner in response to a pressure differential indicative of air flow to the burner, the pressure differential being impressed across a diaphragm which actuates a bleed valve controlling the pressure on one side of the diaphragm actuator of a fuel valve. The bleed chamber is connected to the outlet of the gas valve and the low pressure side of a pressure differential through separate flow restrictors.
