• The model GT burner (IIST-GS1) follows a unique burner design in terms of a broad bluffbody and a narrow annulus for the swirling airflow to issue out.

• The swirling motion is imposed on the main air-flow by means of a radial swirler consisting of 12 channels.

• The non-premixed burner produces a lifted flame under the investigated conditions.

• The design of the non-premixed and swirl stabilized burner is specially attuned to enable fast mixing, flame stabilization, and ultra-low emissions.
