OVEN APPLIANCE WITH FLAME PROVING
An oven appliance includes a cabinet and a chamber defined within the cabinet for receipt of food items for cooking. A gas burner is positioned in the cabinet, and a first temperature sensor is positioned proximate the gas burner. A second temperature sensor is distal from the first temperature sensor and the gas burner. The second temperature sensor is positioned and configured to measure a temperature in the chamber. A controller is positioned within the cabinet. The controller is configured for measuring a first temperature with the first temperature sensor, measuring a second temperature with the second temperature sensor, calculating a difference between the first temperature and the second temperature, and determining a flame is emanating from the gas burner in response to a positive difference between the first temperature and the second temperature.
Barbecue arrangement
A barbecue arrangement comprising a barbecue body having a cooking volume, one or more burners positioned to provide heat to the cooking volume; a gas source adapted to supply a gas to the one or more burners, and one or more control means to control the flow of gas from the gas source to the one or more burners producing a flame when the gas is ignited; a flame detection assembly, the flame detection assembly adapted to sense the flame from the one or more burners and a control means adapted to shut off the gas flow to the one or more burners if the flame is not detected within a pre-determined period of time.
METHOD FOR DETECTING THE PRESENCE OF FLAME IN A PREMIXED HYDROGEN BURNER
The object of the present invention is a control method for verifying the presence of the flame in the combustion chamber (41) of a premixed gas burner (1), fed by an air and gas mixture mainly and/or essentially comprising hydrogen H2. The method is based on the use of at least one temperature sensor (6), the values whereof are sent to a control device (8) which uses them to calculate the derivative T over time of the temperature T to compare it to suitable feedback thresholds (Tau1, Tau2; Tau3, Tau4) to establish the ignition occurred, the ignition failure or flame extinguishment.
