Abstract
A process and burner for the partial combustion of a finely divided solid fuel, wherein coal and oxygen is supplied to a reactor space via a central coal passage and a plurality of inwardly inclined oxygen outlet passages supply oxygen. Each oxygen jet is surrounded by a shield of a moderate gas from an annular passage, preventing premature contact of free oxygen with reactor gas and the premature escape of solid fuel, broken-up by the oxygen jet from the break-up zone.
