Abstract (en)

A burner device (1) for supplying a mixture (MG) of a fuel gas (F) and a combustion-supporting gas (A) into a combustion region (R) includes: a primary mixing path (27) configured to be introduced with and mix the fuel gas and the combustion-supporting gas; a secondary mixing chamber (33) defined inside a wall surface having a rotating-body shape and configured to be introduced with and further mix the mixture (MG) from the primary mixing path (27); and a plurality of mixture introduction holes (35) defined in a circumferential wall (5a) of the secondary mixing chamber (33) and configured to introduce the mixture (MG) from the primary mixing path (27) into the secondary mixing chamber (33) in an eccentric direction of the secondary mixing chamber (33) to generate a swirling flow of the mixture (MG).
