ABSTRACT OF THE DISCLOSURE: In a process of carrying out high-temperature reactions between a hot gas and preheated solids, which when treated at a high temperature, are no longer free flowable, the preheated solids are supplied from below in the direction of conveyance through a burner flame, which is disposed in the lower portion of a conveyor passage. When the solids have been conveyed throughout the length of a sufficiently long reaction zone and the desired reaction has been completed, the gas-solids suspension still flowing in the same direction is contacted with a separately introduced coolant at a point succeeding the reaction zone and is thus cooled to a temperature at which the solids are free flowable. The solids are preferably preheated in a circulating fluidized bed, which is supplied with an oxygen-containing fluidizing gas and with an oxygen-containing secondary gas and in which the exhaust gases from the conveyor passage are used. When the solids have been separated from the gas, they are cooled in a fluidized bed cooler.
