Abstract: A sintering furnace with a first zone, in particular a burn-off zone, and a second zone, in particular a sintering zone, and also a transitional zone arranged between the first zone and the second zone. The sintering furnace has at least one transporting mechanism for transporting bodies to be sintered on a transporting area. With this transporting mechanism, the bodies to be sintered can be transported from the first zone and through the transitional zone to the second zone. The sintering furnace also has at least one gas removal device with at least one gas removal device opening. Here, the gas removal device opening is at least partially arranged in the region of the transitional zone. Furthermore, a method by means of which gases can be removed from a sintering furnace is claimed.
