A coke dry quenching device (100) comprises a pre-chamber (112) having a cylindrical wall (116) extending along a vertical axis (A) and comprising a coke inlet aperture (120) through which hot, granular coke is fed into the pre-chamber (112); and a quenching chamber (114), below the pre-chamber (112). The quenching chamber (114) includes a cylindrical wall (122) in axial continuity of the pre-chamber to receive the descending coke; gas supply means (128, 129) for supplying cooling gas inside the quenching chamber; and a coke discharge aperture (124) at the bottom of the quenching chamber. A plurality of gas outlet apertures (130) circumferentially distributed in a tran-sition region at the top of the quenching chamber (114), through which cooling gas is evacuated into gas flues (132) joining into an annular collection channel (134) surrounding the pre-chamber (112) above the gas outlet apertures (130). The cylindrical wall (116) of the pre-chamber (112) is supported at its bottom by a plurality of peripherally distributed, substantially vertical support columns (136) resting on the cylindrical wall (122) of the quenching chamber (114). |
