摘要：The present invention proposes a method for feeding a burden to a blastfurnace (), wherein the method comprises providing a charging device () having at least
one material hopper (), the material hopper () comprising a hopper chamber (), a materialinlet aperture for feeding a burden into the hopper chamber (), and a material dischargeaperture for feeding a burden from the hopper chamber () to the blast furnace (); thematerial inlet aperture having an associated inlet seal valve ) for opening and closing thematerial inlet aperture and the material discharge aperture having an associated materialdischarge valve () for opening and closing the material discharge aperture. The methodfurther comprises opening the material inlet aperture and closing the material dischargeaperture; feeding a burden into the hopper chamber () through the material inletaperture; closing the inlet seal valve (); pressurizing the hopper chamber () by feedingpressurizing gas into the hopper chamber (); and opening the material discharge valve ()and feeding the burden from the hopper chamber () to the blast furnace (). According toan important aspect of the invention, the method comprises feeding a predeterminedamount of pressurized flushing gas through the hopper chamber () before pressurizingthe hopper chamber (), wherein the flushing gas comprises at least 75% carbon dioxide.
