摘要： A batch furnace for annealing material, in particular a single chamber furnace or single coil furnace, with a furnace housing. The batch furnace has a closable charging opening, a receiving chamber for receiving furnace material, and a device for convective heat transfer onto the furnace material by a heat transfer medium. The batch furnace includes at least one fan, which is arranged in the furnace housing, at least one heating device for the heat transfer medium and/or at least one inlet for an externally heated heat transfer medium, wherein the heating device and/or the inlet is arranged directly in front of the intake side or directly behind the pressure side of the fan or circumferentially in an annular gap between the fan and the furnace housing, and a receiving chamber for the furnace material, which is arranged on the pressure side of the fan.
