Abstract of the disclosure An improved heat exchanger for gas is disclosed, of the type having series of staggered and horizontally disposed sets of tubes and restricted at its lower end by means of a bottom through which the gas may penetrate and at its upper end by the uppermost set of tubes, and over its entire vertical length containing a granular material which is kept in movement by the gas stream which is flowing essentially vertically upwards through the heat exchanger. The heat exchanger is characterized therein that the ratio between the diagonal free opening a and the horizontal free opening b between the tubes in the set of tubes lies within the range of from 0.45:1 to 0.9:1 for controlling and restricting the vertical movement of the grains in the heat exchanger, thereby obtaining an approximately continuous temperature gradient in the gas-grain mixture over the entire height of the heat exchanger.
