Abstract

The invention relates to an ozone supply unit ( 26 ) for a flame burner apparatus and/or an oxygen cutting apparatus ( 10 ), comprising an oxygen inlet ( 28 ) to be supplied with oxygen ( 18 ), an ozone generator ( 32 ) coupled to the oxygen inlet ( 28 ) and configured to convert at least a part of the oxygen ( 18 ) supplied to the oxygen inlet ( 28 ) into ozone ( 18 a ), and an outlet ( 30 ) coupled to the ozone generator ( 32 ), wherein the outlet ( 30 ) provides at least a part of the oxygen ( 18 ) supplied to the oxygen inlet ( 28 ) and at least a part of the ozone ( 18 a ) converted by the ozone generator ( 32 ). The ozone supply unit ( 26 ) is configured to be integrated into a flame burner apparatus and/or an oxygen cutting apparatus ( 30 ). The invention further relates to a method for supplying ozone to a flame burner apparatus and/or an oxygen cutting apparatus ( 30 ).

First claim

The invention claimed is:

1. An ozone supply unit ( 26 ) for a flame burner apparatus and/or an oxygen cutting apparatus ( 10 ), comprising:
an oxygen inlet ( 28 ) to be supplied with oxygen ( 18 );
an ozone generator ( 32 ) coupled to the oxygen inlet ( 28 ) and configured to convert at least a part of the oxygen ( 18 ) supplied to the oxygen inlet ( 28 ) into ozone ( 18 a ), wherein the ozone generator ( 32 ) comprises two electrodes ( 34 ) arranged between the oxygen inlet ( 28 ) and the outlet ( 30 ) and wherein the electrodes ( 34 ) are connectable to a power source and are positioned so that a plasma can be generated between the two electrodes ( 34 );
an outlet ( 30 ) coupled to the ozone generator ( 32 ) for discharging from the ozone supplying unit (a) at least a part of the oxygen ( 18 ) that was supplied to the oxygen inlet ( 28 ) and not converted into ozone in the ozone generator and (b) at least a part of the ozone ( 18 a ) formed by the ozone generator ( 32 ); and
a dielectric member ( 36 ), arranged concentrically with the two electrodes ( 34 ) forming gaps through which the supplied oxygen ( 18 ) can stream through the ozone generator ( 32 ), the gaps forming a reaction chamber ( 37 ) in which the plasma is generated.

2. A method for providing ozone for a flame burner apparatus or for an oxygen cutting apparatus ( 10 ), the method comprising:
supplying oxygen ( 18 ) to the flame burner apparatus or to the oxygen cutting apparatus ( 10 ),
wherein said oxygen cutting apparatus comprises a cutting head, an oxygen supply line, and an ozone supply unit ( 26 ), wherein said ozone supply unit ( 26 ) is integrated in the cutting head and/or the oxygen supply line, and said flame burner apparatus comprises a burner head, an oxygen supply line, and an ozone supply unit, wherein said ozone supply unit ( 26 ) is integrated in the burner head and/or the oxygen supply line;
converting at least a part of the oxygen ( 18 ) supplied to the flame burner apparatus or to the oxygen cutting apparatus ( 10 ) into ozone ( 18 a ) by generating a plasma between the at least two electrodes of the ozone supply unit ( 26 ); and
providing at least a part of the ozone ( 18 a ) converted by the ozone supply unit ( 26 ) and at least a part of the non-converted oxygen ( 18 ) to a combustion process via the flame burner apparatus or to an oxygen cutting process via the oxygen cutting apparatus ( 10 ), respectively,
wherein the ozone supply unit ( 26 ) comprises: an oxygen inlet ( 28 ) to be supplied with oxygen ( 18 ); an ozone generator ( 32 ) coupled to the oxygen inlet ( 28 ) and configured to convert at least a part of the oxygen ( 18 ) supplied to the oxygen inlet ( 28 ) into ozone ( 18 a ); and an outlet ( 30 ) coupled to the ozone generator ( 32 ) for discharging from the ozone supplying unit (a) at least a part of the oxygen ( 18 ) that was supplied to the oxygen inlet ( 28 ) and not converted into ozone in the ozone generator and (b) at least a part of the ozone ( 18 a ) formed by the ozone generator ( 32 );
wherein the ozone supply unit ( 26 ) is integrated in a cutting head ( 12 ) of an oxygen cutting apparatus or is integrated in a burner head of a flame burner apparatus;
wherein the ozone generator ( 32 ) of the ozone supply unit ( 26 ) comprises two electrodes ( 34 ) arranged between the oxygen inlet ( 28 ) and the outlet ( 30 ) and further comprises a dielectric member ( 36 ), arranged concentrically with the two electrodes ( 34 ) forming gaps through which the supplied oxygen ( 18 ) can stream through the ozone generator ( 32 ), the gaps forming a reaction chamber ( 37 ) in which the plasma is generated, and
wherein the converting of at least a part of the supplied oxygen ( 18 ) into ozone comprises generating a plasma within said reaction chamber ( 37 ).

3. The ozone supply unit according to claim 1 , wherein the ozone supply unit is integrated into a flame burner apparatus or is integrated into an oxygen cutting apparatus.

4. The ozone supply unit according to claim 1 , wherein the ozone supply unit is integrated into a cutting head of an oxygen cutting apparatus or is integrated into a burner head of a flame burner apparatus.

5. The ozone supply unit according to claim 1 , wherein the ozone supply unit is integrated into an oxygen supply line of an oxygen cutting apparatus or into an oxygen supply line of a flame burner apparatus.

6. An oxygen cutting apparatus comprising a cutting head, an oxygen supply line, and an ozone supply unit which is integrated into the cutting head or into the oxygen supply line, wherein said ozone supply unit is according to claim 1 .

7. The oxygen cutting apparatus according to claim 6 , further comprising a cutting head, wherein the ozone supply unit is integrated into the cutting head.

8. The oxygen cutting apparatus according to claim 7 , wherein the oxygen inlet of the ozone supply unit is in direct communication with an oxygen inlet of the cutting head and/or wherein the outlet of the ozone supply unit is in direct communication with an outlet nozzle of the cutting head.

9. A flame burner apparatus comprising a burner head, an oxygen supply line, and an ozone supply unit which is integrated into the burner head or into the oxygen supply line, wherein said ozone supply unit is according to claim 1 .
