Abstract A computational code has been developed based on a Eulerian–Lagrangian approach in order to model the combustion and the motion of perlite particles in a vertical expansion furnace. The expansion of a single particle, which takes place during its motion in the furnace, has been modeled by taking into account the perlite chemical composition and the gradual variation of the temperature distribution inside the grain. Experiments, performed in a perlite expansion plant, have been used to validate the computational results. The operational characteristics of a perlite expansion furnace have been measured and have served as inlet conditions for the numerical simulation of the combustion and perlite expansion processes. The good agreement between measurements and predictions indicates that the developed computational tool can be used to optimise the perlite expansion process leading to reduced fuel consumption with increased productivity.
