Claims18
A lance of a gas turbine burner comprising:
- an inner duct having inner nozzles;
- an annular outer duct encircling the inner duct and having outer nozzles;
- a spacer disposed downstream of the inner nozzles and outer nozzles between a terminal portion of the inner duct and a terminal portion of the outer duct, the spacer being fixed to both the inner duct and the outer duct, and wherein the spacer extends in a radial direction in an annular section between the inner duct and the outer duct;
- wherein the inner duct includes an inner duct seat, the spacer extending from the outer duct to the inner duct so as to rest in the inner duct seat, and a fixing element configured to block the spacer in the inner duct seat;
- wherein the outer duct includes an outer duct seat, the spacer extending from the inner duct to the outer duct so as to rest in the outer duct seat, and a fixing element configured to block the spacer in the outer duct seat;
- and
- a wall closing the terminal portion of the outer duct, wherein the wall is a separate element from the outer duct and connected to the outer duct.
