[origin: WO2004076923A1] The invention relates to a system for supplying combustion air (10) and liquid fuel (12) into a burner (14), said system comprising a Venturi nozzle (16) for supplying the combustion air (10), and a fuel needle (18) which is arranged in the combustion air flow region and is used to supply the liquid fuel (12). The invention is characterised in that the formula 0.7 = di/da < 1 holds good for the ratio of the inner diameter di to the outer diameter da of the fuel needle (18). The invention also relates to a heating appliance comprising one such system.
