Abstract: An increase in the throughput in the BMA-furnace or a BMA furnace chamber, respectively, without modification of the existing design and dimensions is achieved by converting the lower stage of the cooling head to a short-tube bundle-type heat exchanger whilst retaining the temperature profile needed for the process by the denser or less dense arrangement of the ceramic tubes in the furnace chamber and/or by using ceramic tubes having different inner and outer geometry and/or structure.
