Coal and oxygen are supplied to a reactor space (10) via a central coal passage (9) and a plurality of inwardly inclined oxygen outlet passages (13), respectively. Each oxygen jet from an outlet passage (13) is surrounded by shield of a moderator gas from an annular passage (17), 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. |
