Beschreibung
Zusammenfassung:	A feed inlet structure (10) for a burner (4) for a suspension smelting furnace comprises an inlet space (14) defined inside the feed inlet structure. The feed inlet structure (10) further comprises an inlet opening (15) and a feed distributor (16) provided at least partly within the inlet space (15). The feed distributor (16) is configured to separate objects from a standard feed, which objects have a particle size that is larger than a maximum particle size of the standard feed. The feed distributor (16) comprises at least one dividing plate (17) comprising a first side (18) having a first surface (19). The first surface (19) of each dividing plate (17) is configured to deviate a trajectory (27) of at least some objects from a trajectory (28) of the standard feed inside the feed inlet structure (10), when feed material comprising standard feed and objects is fed to the feed inlet structure.
