When carrying out a radiant heat exchange between two media, one medium being a hot gas (5) and the other medium being a gasification mixture (11) of fuel and steam, the device consists of a gasification vessel (1) which, for its part, consists of a reaction space (2), an intermediate tube (4) and a flow space (3). In the reaction space (2), the hot gases (5) flow away centrally in the direction of the intermediate tube (4) and the flow space (3). The gasification mixture (11) flows in the opposite direction out of the flow space (3) and the intermediate tube (4). This gasification mixture surrounds the hot gases (5) in such a way that the radiant heat exchange takes place between the two media (5, 11).
