There is provided a bustle pipe arrangement of a shaft furnace, in particular for feeding hot gas into the shaft furnace such as e.g. a blast furnace, wherein the bustle pipe arrangement comprises a circumferential bustle pipe arranged along the outer casing of the shaft furnace, at a certain distance therefrom. The arrangement further comprises a plurality of first support arms connecting the bustle pipe to the outer casing of the shaft furnace on a first level; and a plurality of second support arms connecting the bustle pipe to the outer casing of the shaft furnace on a second level, the first level being separate from the second level. The first and second support arms are configured to support the circumferential bustle pipe. First blow channels are arranged through the first support arms for fluidly connecting the bustle pipe to the interior of the shaft furnace.
