INNOVATIVE METHOD OF CALCINATION IN TWIN SHAFT REGENERATIVE KILN
Method for the production of lime carried out in a suitable twin shaft regenerative calcination furnace, said furnace comprising one or more blowers, all provided with frequency converters, and a plurality of process valves among which at least one releasing valve and at least one by-pass valve, said method, cyclically and alternately between the two shafts, comprising a step of fuel injection and combustion, a step of combustion nozzles washing and a step of lime discharge and limestone load, characterized in that during the washing, discharge and load steps, said releasing and by-pass valves are not moved since said blowers are kept off with consequent reduction of the furnace inversion time. As a consequence there are provided the following improvements in terms of efficiency as the inversion time reduction and the consequent increase in production, a total air flow rate according to the air excess, the absence of noise and powder coming from the releasing and stress relieving valves and a lower electric energy consumption.
