Abstract
The invention relates to a silo for storing dried bulk products containing organic materials, in particular for storing dried sludge from residual water treatment plants, said products being subject to self-heating phenomena, wherein said silo includes an outer shell (1) having an upper portion and a lower portion, the shell being made of an essentially metallic heat-conducting material and comprising at least an inlet and an outlet for the products, a roof (2) closing the silo in the upper portion, and a discharge device (3) closing the silo in the lower portion. The silo includes at least one inner stack (5) of an essentially metallic heat-conducting material that communicates with the atmosphere in the upper and lower portions, the volume inside the stack being void so as to permit air circulation and heat dispersal, and the ratio d/D between the outer diameter d of the stack (5) and the outer diameter D of the shell being higher than 0.12.
