Title: SINTERING EQUIPMENT, A PLANT FOR EXPLOITING DUST AND WASTE FROM IRON PRODUCTION AND USE THEREOF
Abstract:
The disclosure relates to sintering equipment for con- tinuous sintering of pelletized mineral material. The sintering equipment comprisesa sintering furnace (1), comprising sequential process zones (I-VII), the tem- perature conditions in each process zone being inde- pendently controllable; theprocesszones comprising at least one drying zone (I), at least one heating zone (II), at least one sintering zone (III, IV) and at least one cooling zone (V, VI VII). The sintering equipment further comprises a gas-permeable conveyor belt (3) for conveying the mineral material through the process zones (I-VII)andcirculation gas ducts (4a, 4b, 4c). The sintering equipment is characterized in that thecirculation gas duct conducting gas to the at least one drying zone comprises at least oneburner (B) for controlling the gas temperature in the at least one drying zone.The disclosure further relates to use of the sintering equipment and to a plant.
