AN AIR-GAS MIXTURE BURNING APPLIANCE WITH A VARIABLE EQUIVALENCE RATIO IGNITION SEQUENCE

AN AIR-GAS MIXTURE BURNING APPLIANCE WITH A VARIABLE EQUIVALENCE RATIO IGNITION SEQUENCE

In an air-gas mixture burning appliance (100) that comprises a burning unit (120) for burning a combustible air-gas mixture (130, 131), a flame detector (150) for sensing presence of a flame (122) in the burning unit (120), an air-gas mixing unit (110) that is arranged upstream of the burning unit (...

Zusammenfassung:In an air-gas mixture burning appliance (100) that comprises a burning unit (120) for burning a combustible air-gas mixture (130, 131), a flame detector (150) for sensing presence of a flame (122) in the burning unit (120), an air-gas mixing unit (110) that is arranged upstream of the burning unit (120) for mixing of air and gas to form the combustible air-gas mixture (130, 131), and a gas supply unit (116) that is arranged upstream of the air-gas mixing unit (110), the gas supply unit (116) is adapted to regulating a flow of gas to the air-gas mixing unit (110) such that the combustible air-gas mixture (130, 131) has a variable equivalence ratio between gas and air that is based on whether the flame detector (150) senses the presence of the flame (122) or fails to sense the presence of a flame (122) in the burning unit (120).
