The invention relates to a mobile device for flame cleaning concrete, reinforced concrete or prestressed concrete or materials of a similar constitution, with at least one pressure nozzle, in each case one adjoining jet chamber and in each case one 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. A plurality of burner heads (12) adjacent to one another and arranged in one plane are arranged on a platform connected to a vehicle (10), or on a chassis, and the vehicle has a super creeping speed and a wheel reduction by means of wheels reduced in size by the same ratio. The vehicle is designed as a tractor with a combustion engine and all-wheel drive. The tractor can be set to a minimum cruising speed of 0.5 m/min and the front wheels are made of solid rubber. The supply pipes to the burner heads are bundled over a high frame connected to the tractor and guided to a following vehicle. The supply pipes are pipes for combustible gas and oxygen and supply and drainage pipes for the coolant. <IMAGE>
