Device for economising on heat in a rotary furnace, in particular a furnace for the recalcination of calcium-rich sludge. Baffles 7, 8, 9 are fixed centrally in the furnace 1, in order to push the hot combustion gases back towards the wall of the furnace, which considerably improves the heat transfer to the calcium-rich sludge or other material treated. <IMAGE> |
