Abstract (en)

[origin: GB2484957A] A burner control system for controlling operation of a burner 1 includes a control unit 10 that controls the flow of air in duct 5 and fuel (gas in duct 2) with valves 4,7 and fans 3,6, receives inputs of ambient air pressure and/or temperature from sensors 14, 15 & from an exhaust gas analysis system 9, and uses the inputs to trim the proportion of air to fuel fed to the burner, the control unit 10 having a store 13 in which pairs of valve settings for air and fuel are stored together with readings of gas pressure from a sensor 11 and of air pressure from a sensor 12. The burner can be for heating a large building. The system uses the stored values for initial control until gas analysis data is available, and can use the pressure readings to identify a fault.
