A dust recycling system to capture dust from reduction gas and inject the same back into the melter gasifier for dust burning in a smelting reduction iron making process comprising a hot gas cyclone (HGC) a dust bin (LDB) in operative connection to said hot gas cyclone for continuous flow of the captured dust through a hot knife gate and valve vertical pipelines provided at an inclination ranging from 40 to 120 preferably 80; said dust bin (LDB) further operatively connected through a vertical pipeline and an inlet to a high dust volume T-piece (TP) comprising of injector and diffuser means; and a melter gasifier having dust burner to burn the dust thus recycled into the melter gasifier through said T-piece. The above system is adapted to favour effective and jam free transportation of dust from the hot gas cyclone to the dust burner and thereby improve plant availability/efficiency.
