BURNER FOR POWDER FUEL GASIFICATION

摘要

The invention relates to a burner for the vaporisation of coal dust to supply a reactor. The burner comprises a plurality of coal dust/carrier gas supplies 2 with a circular cross-section which merge in the burner housing 3 into sections of circular rings of the same diameter arranged concentrically round a central pipe 1 conveying vaporisation medium, which sections are equal in area to the associated coal dust/carrier gas supply over the whole distance of a profile change in the cross-section of flow and which, together, form a substantially closed but not joined 360 DEG circular ring at the burner mouth, as a result of which a uniting of a plurality of streams of dust is effected and a symmetrical uniform distribution of dust is ensured in the combustion reaction chamber.
