Abstract (en)
An industrial installation (1) for waste radiative heat recovery from steel slag, said installation (1) being located above a pit (2) in which molten steel slag is discharged and from which solidified steel slag is removed, using a slag conveying machine or vehicle. This installation includes :- an evaporating device (3) for producing hot water and steam and auxiliary equipment, said evaporating device comprising a heat exchanger (6) under the form of tube-cooled walls ;- a steel structure (4) supporting said evaporating device ;characterized in that the installation further comprises a lifting system using jacks (5), so that the heat exchanger (6) under the form of tube-cooled walls can be moved vertically from an upper standby position to a lower working position and vice versa. The link between fixed and moving water circuits is performed thanks to flexible hoses.
