Beschreibung
Zusammenfassung:	11 48,104 A coaxial feed system for fluidized bed coal gasification processes including an inner tube for injecting pariculate combustibles into a transport gas, an inner annulus about the inner tube for injecting an oxidizing gas, and an outer annulus about the inner annulus for transporting a fluidizing and cooling gas. The combustibles and oxidizing gas are discharged vertically upward directly into the combustion jet, and the fluidizing and cooling gas is discharged in a downward radial direction into the bed below the combustion jet.
