1. A method for producing hot gas for operating a turbomachine fired using at least one combustion chamber, the method comprising: providing a burner arrangement upstream of the combustion chamber, the burner arrangement including a swirler and a mixing tube;premixing a fuel including natural gas with air in the swirler so as to create an air/fuel mixture;injecting an H2-rich fuel into the air/fuel mixture so as to produce a premixed fuel by injecting the H2-rich fuel into the mixing tube; andintroducing the premixed fuel into the combustion chamber. 2. The method as recited in claim 1, wherein the injecting the H2-rich fuel includes injecting a ratio of the H2-rich fuel of at most 30% to the natural gas. 3. The method as recited in claim 1, wherein the introducing the fuel is performed at an angle. 4. The method as recited in claim 3, wherein the angle is between 20° and 120°. 5. The method as recited in claim 1, wherein the burner arrangement includes a fuel lance projecting into a hot gas flow, and further comprising injecting the fuel mixture into the hot gas flow using the fuel lance. 6. The method as recited in claim 5, wherein the at least one combustion chamber includes a second combustion chamber, and further comprising operating the second combustion chamber using a self-igniting combustion process, wherein the introducing is performed using the at least one fuel lance. 7. The method as recited in claim 6, further comprising operating at least one vortex generator upstream of fuel lance. 8. The method as recited in claim 6, further comprising disposing at least one further injection device downstream of the fuel lance. 9. The method as recited in claim 6, wherein the introducing includes feeding air with the at least one fuel. 10. The method as recited in claim 9, further comprising feeding air into the at least one fuel separately. 11. The method as recited in claim 9, further comprising admixing air with the at least one fuel.
