Inlet and outlet means 6, 7, 8, 9 are provided for supplying and withdrawing the coarse and the powdered solids respectively at the base thereof and for withdrawing and supplying the coarse and the powdered solids respectively at the top thereof. The time of stay of the coarse solid may be varied by either having a screw of non-uniform pitch or varying the speed of rotation of the screw 5.  On the other hand the time of stay of the powdered solid may be varied by a variation of the angle of inclination of the tube 1.  In an alternative embodiment the casing 1 may be fixed and the screw 5 rotated within.  The heat exchanger is particularly applicable to the carbonization of calibrated coal agglomerator (Fig. 2, not shown).  The calibrated coal agglomerates enter the heat exchanger at 6 and a hot thermophorus, e.g. sand or crushed brick, enter at 7.  Any thermophorus carried away by the carbonized agglomerates is separated by a screen (13) and conveyed with the thermophorus from the heat exchanger outlet 9 by means of a flow of air or oxidizing gas in a conduit (10) to the base of a fluidization re-heat reactor (11) in which the coal and coke dust collected by the thermophorus during its passage through the heat exchanger acts wholly or partially as the fuel to re-heat the thermophorus before it is returned via a dedusting cyclone (12) to the heat exchanger. Additional heat may be provided by a supply of gas or fuel oil to the centre of the re-heat reactor (11).  An alternative embodiment (Fig. 3, not shown), employs the residual heat in the carbonized agglomerates at the exit 8 from the heat exchanger, by means of a second heat exchanger (1A) according to the invention, to pre-heat the thermophorus before it passes into the re-heat reactor (11).  Any thermophorus carried away by the carbonized agglomerater is separated by a screen (13A) and returned to the re-heat reactor.
