1. A machine for thermal treatment of bulk material, comprising:
a stationary furnace which presents a support structure, and
a plurality of pallet cars traveling through the furnace along a traveling direction, wherein a series of the plurality of pallet cars located within the stationary furnace together define, at lateral sides of the plurality of pallet cars, a common engagement surface which extends through the furnace along the traveling direction,
wherein the support structure of the furnace and the common engagement surface of the series of pallet cars of the plurality of pallet cars define a gap therebetween, said gap having a gap length along the traveling direction, the machine further comprising:
a sealing system comprising:
one or more drop bars distributed after each other along the traveling direction;
wherein each drop bar of the one or more drop bars includes a brush arranged on the drop bar such that the brush is configured to be in engagement with the common engagement surface such that the one or more drop bars covers the gap over at least parts of the gap length.
