Proposed is a device for coating substrates by means of high-velocity flame spraying. The device comprises a combustion chamber (4), a first fuel feeder (L1) for feeding a liquid or gaseous fuel as well as at least one gas feeder for feeding an oxidative gas. The devise comprises furthermore a second fuel feeder (L5) for feeding a liquid or gaseous fuel as well as at least one further gas feeder for feeding a gas. Both the first gas feeder and the two fuel feeders (L1, L5) port into a common combustion chamber (4). In addition, means 24, 28 are provided for independent control of the fuel feed into the two fuel feeders (L1, L5).
