A hot blast main mixer stage comprises a section of hot blast main (2) and a plurality of cold blast inputs (12, 13, 14) to the section. The inputs are spaced about a circumference of the main (2) in an asymmetric arrangement at least one of the inputs (14) is radial, converging at a common centre and at least one of the inputs (12, 13) is non-radial, converging, not at the common centre, or diverging from the common centre. |
