PURPOSE:To obtain a supersonic combustion device, which enables to realize uniform blue flame combustion, by a small sized structure wherein a guide space and a conical roof are arranged in a passage of the air and fuel. CONSTITUTION:A guide member 6 partitions a guide space 8 by being positioned in the relationship to coincide the axis line of the member 6 with that of a vessel 2. Airy swirling flow 26 is produced in the guide space 8 with regard to all the air introduced in an interior space 14 in order to favorably mix with fine atomized fuel in the guide space 8 at the lower end of a roof 12. Uniform blue flames 28 can be formed at the upper part of slits 19 by leading said resultant mixture out of a gap 11 between the roof 12 and the guide member 6. Because the roof 12 has a shape convexed upwards and is installed at the position so high as to be directly striken by liquid column 22, the height of a burner is made smaller. In addition, the fuel 27, which is scattered upward without being finely divided from the liquid column 22, is rendered to adhere to the roof 12 and to be recovered along the inner peripheral wall of the guide member 6.
