Abstract
A system for the thermal treatment of work pieces with an explosive gas mixture, in particular, a thermal deburring system, has a processing chamber ( ), which includes a combustion chamber ( ) for receiving the work pieces. A supply channel ( ) for the gas mixture opens into the combustion chamber ( ). In the combustion chamber ( ), a device is provided, which has a plurality of openings through which the flame front passes for thermally treating the work pieces. The device can be one that connects to the supply channel ( ), preferably in the form of a tube ( ) with a plurality of openings ( ), which can be made from an extruded sheet. The work pieces obtain a more uniform processing or deburring effect, since the flame front passes through the many small openings of the device. The small openings ( ) serve also as throttles, whereby the entire combustion process runs for a longer time.
