Claims7
A device for thermal deburring of workpieces, comprising:
- at least one deburring chamber having a chamber wall and a feed means for introducing a combustible fuel gas mixture into the deburring chamber,
- a central valve connected to a passageway extending through the deburring chamber wall, wherein the passageway is separate from the feed means, and wherein the central valve is external to the deburring chamber and is an outlet through which the fuel gas mixture can be removed from the deburring chamber, and
- a supplementary gas feed connected and in communication with the central valve, and upstream of an outlet of the central valve with respect to an outflow direction of the fuel gas mixture,
- wherein the supplementary gas is any gaseous substance which when mixed with the fuel gas mixture forms a discharge mixture with a reduced risk of ignition from that of the fuel gas mixture.
