Definitions

the gas consisting of air consists of hot air coming from an air cooling zone of the calcined material or cooked evacuated from the calcination zone.
the residence time in the system for treating the pulverulent material can be modulated as desired before the calcination or actual cooking so as to adapt the residence time as a function of the specificity of the pulverulent material or of the component causing an exothermic reaction or combustible component.
the residence time in the post-combustion zone can be modulated so as to reduce the rate of unburnt material coming from the pre-calcination zone by a limited quantity of gas. oxidizer, generally air.
the calcination oven 101 or baking is a rotary oven which is provided with a smoke box 108 by which the gases from the calcination oven 101 or baking go up through a conduit 109 leading to the pre -calciner 103.
the mixture of the pulverulent material, the combustible component and the gases, in particular combustion air, are evacuated from the precalciner 103 by a conduit 110 towards the pre-heating system, comprising a stage separation bottom 106 separating gases from solids.
