Kind Code:
B2
Abstract:
Plant and process for precalcining any mineral matters. This plant comprises essentially a precalciner (2) consisting of a combustion chamber (20) communicating via a sleeve (21) with a reaction chamber (22) itself communicating via a conduit (24) with a separating cyclone (25), the reaction chamber (22) being fed with fumes (11) originating from a firing oven, and three conduits (27, 28, 31) feeding the combustion chamber (20), a volute (29) in the region of a burner (30) and the conduit (24), respectively, with hot air originating from a cooler. This plant makes it possible in particular to manufacture cement clinker while considerably minimising the emission of nitrogen oxides.
