A bed 26 of particulate material is moved in a band continuously along an annular path by passing fluid media having both circumferential and vertical components through the bed along that path. The fluid media comprises combustion gases which are passed through the bed along a portion of the path for heating the particulate material as it passes therethrough and fluid matter to be heated which passes through the bed along another portion of its path such that the fluid matter is heated as it passes through the particulate material which has been heated by the combustion gases. |
