A calcination unit able to decarbonate raw materials intended for clinker production, the unit comprising:
- a main duct in which the raw materials circulate according to a first movement direction, the raw materials being calcined in the main duct, the main duct including a recess,
- a solid fuel supply duct opening onto the main duct via a fuel outlet, the fuel outlet opening into the recess, the solid fuel moving according to a second movement direction,
- a retaining device located in the recess of the main duct and arranged opposite the solid fuel outlet so that said solid fuel arriving in the main duct via the fuel outlet is sent towards said retaining device,
- wherein the retaining device includes retaining elements and passages separating two adjacent retaining elements.
