METHOD FOR CALCINING CARBONATED MINERAL STONES IN A PARALLEL FLOW REGENERATIVE KILN AND IMPLEMENTED KILN
Parallel flow regenerative kiln, comprising at least two shafts (1,2) interconnected by a crossover channel (4), each shaft comprising means for injecting a heated gas (6) inside the shaft (1) in calcination working at the top of the calcination zone (B), the kiln further comprising an external recirculation circuit (21) which comprises a separation body (20) for taking off a fraction of gaseous effluent from a removal duct (17), an external electrical furnace (23) connected with said separation body (20) and equipped with at least one plasma torch (24) for heating a gaseous flow and with a mixing chamber (25) wherein said heated gaseous flow is mixed with a control gas, which has not been heated by said electrical furnace (23), while so forming a first mixture to inject under the form of a heated gas, and said means for injecting a heated gas (6, 7) inside the shaft (1) in calcination working, which are connected to the mixing chamber (25) and inject said first mixture to inject at a temperature equal or higher than the temperature of calcination of the loaded mineral stones.
