The method comprises supplying cold non- preheated combustion air and dust fuel into a combustion chamber of a boiler through a burner (10) for producing a flame, the combustion air comprising primary air (100), secondary air (200), tertiary air (300). The flame is stabilised by providing a flame stabilising ring (50) at a downstream end of the annular fuel nozzle and primary air is directed through a swirl generator (30) at the primary air nozzle so that primary air has a swirl number (Sp). A stream of tertiary air is guided off with a guide sleeve (40) aligned with a burner throat (41) at an angle (α), so that an inner recirculation zone (IRZ) is formed between a stream of primary air and the stream of tertiary air. The swirl number of primary air is set at 0,4 to 1,0 by the swirl generator; the primary air velocity at the primary air nozzle orifice is set to 30 m/s or less;and the carrier air velocity at the downstream end of the annular fuel nozzle is set to 15 m/s or less. The tertiary air velocity is set so that at the end of the guide sleeve (40), the tertiary air velocity is 35 to 50 m/s. Further disclosed are a burner (10) and a boiler comprising a burner.
