BURNER FOR THE PARTIAL COMBUSTION OF FINELY DIVIDED SOLID FUEL

摘要

Process and burner for the partial combustion of a finely divided solid fuel with oxygen. A core of finely divided solid fuel, surrounded by oxygen or oxgyen-containing gas and an annulus of finely divided solid fuel around the oxygen or oxygen-containing gas are introduced into a reactor space via a burner. The solid fuel is centrally (10) introduced into the burner, whereas oxygen or oxygen-containing gas is separately introduced into the burner outside (14) the central solid fuel channel (10). In the burner the oxygen or oxygen-containing gas is caused to flow inwardly (16) into the central channel (10) for supplying the oxygen or oxygen-containing gas into the reactor space between the core and the annulus of solid fuel.
