摘要： 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).

摘要： Die Erfindung geht aus von einem Verfahren zum Betreiben einer Verbrennungsvorrichtung zur Bereitstellung eines Luft-Brenngas-Gemischstroms aus einem Luftstrom und einem Brenngasstrom, insbesondere einem Wasserstoffstrom, in zumindest einem vorgebbaren Luft/Brenngas-Verhältnis, und zur Verbrennung des Gemischstroms, wobei durch die Verbrennung eine Heizleistung erzeugt wird, wobei eine Luftfördereinheit einen Luftstrom fördert, insbesondere in Abhängigkeit einer Leistungsanforderung, eine Brenngasdosiereinheit einen Brenngasstrom dosiert, insbesondere in Abhängigkeit des Luftstroms, und eine Mischereinheit den Gemischstrom mischt. Die Erfindung ist dadurch gekennzeichnet, dass das Luft/Brenngas-Verhältnis mittels einer Regeleinrichtung in Abhängigkeit der Heizleistung variiert wird, wobei das Luft/Brenngas-Verhältnis bei kleinerer Heizleistung einen größeren Wert annimmt und/oder bei größerer Heizleistung einen kleineren Wert annimmt. Insbesondere wird eine Luftzahl λ des Luft-Brenngas-Gemischstroms auf einen Wert innerhalb eines ausgewählten Luftzahl-Werteintervalls geregelt wird, wobei die Intervallgrenzen von heizleistungsabhängigen Luftzahlverläufen λ = λ(Q) gebildet werden.
