heal.abstract	The paper presents a numerical simulation of the combustion process and of the motion of expanded perlite particles being transported in a vertical expansion furnace. Erosion wear caused by the perlite particle impact on the walls of the furnace is calculated and evaluated for three different furnace-outlet geometries. Locations where erosion wear becomes significant are established. The results demonstrate that the geometry of the outlet of a vertical axi-symmetric furnace determines the velocity of the particles and temperature field inside the furnace with direct consequences on the efficiency of the combustion process and indirectly on the emission levels. Modification of the furnace outlet geometry can additionally control the level of mechanical erosion wear caused on the furnace walls.	en
