Abstract (en)

Method (100) for controlling the operation of a combustion appliance (1), in particular a gas boiler, wherein the combustion appliance (1) is operable between a minimum load (Q<sub>min</sub>) and a maximum load (Q<sub>max</sub>), the method comprising providing (S101) a mixture of air and fuel gas to the combustion appliance (1), controlling (S102) one or more actuators (2, 3) of the combustion appliance (1) to regulate the air flow and/or the fuel gas flow, and defining (S103) a lambda value, the lambda value being an air to fuel gas ratio of the mixture, wherein in a load range between the minimum load (Q<sub>min</sub>) and the maximum load (Q<sub>max</sub>), the lambda value first decreases and then stops to decrease.
