Abstract: To provide gasification of liquid fuel which is admitted by an atomizing nozzle (11, 13) into a gasification space (66). A deflection element (31) is located spaced from an air inlet (55) in order to deflect the mixture of air, recirculated combustion gases and gasified fuel in the gasification space. A flame tube (21) provides for a first (I) recirculation path for hot gases towards a recirculation openings (49). A second recirculation path (II) extends through openings (57, 61, 59) into the deflection element itself which, preferably, is a hollow, essentially shallow conical deflection structure. The deflection element in combination with the flame tube (21) causes recirculation of gases through the first recirculation path (I) back into the gasification space (66). Thus, all structural elements of the gasification space are subjected to recirculated hot combustion gases, so that no droplets from the atomizing burner (13) can adhere, and coke on structural elements.
