Abstract

The invention relates to a furnace for thermally foaming particles of a bulk material, in which the particles to be foamed are introduced into the furnace chamber (14) from above, moved downwards in the furnace chamber (14), heated and inflated, and are removed through a removal opening (4) located on the base of the furnace chamber (14), the volume of said furnace chamber (14) being delimited by an outer shell (1) and an inner shell (2). The inner shell (2) protrudes, from above, into the volume encompassed by the outer shell (1). The lowest point (2.1) of the inner shell (2) lies higher than the base of the outer shell (1) and the lower end of the furnace chamber (14). The inner shell (2) is closed underneath.
