Abstract
A burner apparatus comprising in axial alignment a cylindrical first section connected through a restrictive opening to a frustoconical second section having its largest diameter at the downstream end and an axial outlet opening at the downstream end. Tangential combustion supporting gas inlets aligned in the same rotational direction are located in the cylindrical section and at the downstream end of the frustoconical section. The outlet opening in the frustoconical second section is of greater diameter than the restrictive opening between the sections and is of lesser diameter than the upstream end of the frustoconical second section so that a stable flame is produced in the second section, there is an inflow of external gas through the outlet opening, and a flow of combustion supporting gas in an upstream direction along the wall of the second section. A method for burning fuel in combustion supporting gas, particularly adapted to produce carbon black, is also provided.
