Abstract: Lumpy or granular material to be heat treated, e.g. in a degasification, calcination, polymerization, endothemic reaction process passes through a shaft-like chamber 1, Fig. 1, formed a high-frequency field, and which have provide a high-frequency field, and which have permeable walls 3 for the supply and/or withdrawal of gaseous or vaporous substances into or from the chamber. Each electrode is constructed as a hollow body subdivided into alternate inlet and outlet compartments a, b by partitions 7 having pipes in the outer, impermeable walls connected to suction or pressure blowers 8. The inlet or outlet apertures 3 may be of locally varying cross-section, be greater in number in the centre of the electrode than at the ends, or the apertures may be covered or be in the form of louvres. In a modification the material is conveyed horizontally through the chamber on a conveyer belt in the form of an electrode, and in a further embodiment the material moves downwardly under the influence of gravity in a vertical shaft-like frequency field, but may be fluidized by an upwardly directed stream of gas, air or vapour from the hollow spaces of the electrodes.
