PROBLEM TO BE SOLVED: To provide a heat exchanger for solid, in which decrease of a lower calorific value of a carbonized product is not caused even when a high temperature carbonized product is cooled, a large heat transfer area can be secured by a small installation space, operation can be performed by few power, risk of damage of a part is reduced, and further risks of generation of dust, ignition of a carbonized product, and leakage of internal gas are reduced.SOLUTION: A heat exchanger for solid includes: a cylindrical shell 1 disposed as extending longitudinally in which a heating medium is supplied in the inside; and a hollow part 4a that is disposed to extend longitudinally further in the shell 1 and in which the solid is supplied in the inside from an upper side, wherein the heat exchanger performs heat exchange between the solid and the heating medium. A discharging apparatus 9 that intermittently discharges the solid that has been heat-exchanged is disposed at a solid outlet under the hollow part 4a. |
