The arrangement (10) further comprises a plurality of first arms (22) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace on a first level; and a plurality of second arms (24) connecting the bustle pipe (12) to the outer casing (14) of the shaft furnace on a second level, the first level being different from the second level. First and second blow channels (26, 30) are respectively arranged through the first and second arms (22, 24) for fluidly connecting the bustle pipe (12) to the interior of the shaft furnace.
