The invention relates to a device for flame cleaning concrete, reinforced concrete or prestressed concrete, or materials of a similar constitution, with a pressure nozzle, an adjoining jet chamber and a following mixing tube which leads into a burner head which is connected to a number of individual nozzles arranged parallel to one another, the fluidic connection between the mixing tube and the individual nozzles comprising a longitudinal hole provided in the burner head and designed as a distributor. Arranged in the burner head (1), parallel to the longitudinal hole (8) designed as a distributor to the individual nozzles (17), is a further longitudinal hole (9) which is in fluidic connection to a coolant source (12) via pipe connections (10, 11). The burner head (1) comprises a plurality of head parts (1, 2, 3) and the longitudinal holes (9) for the guidance of which are intended, a coolant in each head part, are connected to one another in series by connecting bridges (13). <IMAGE>
