text: Hydrogen fluoride is recirculated by way of the fan 6 through the gas preheater 8, where it is brought to a temperature higher than or approximating the decomposition temperature to be used, in order to ensure that through substantially the entire course of travel through the reactor the sodium bifluoride will be at the decomposition temperature, having been previously warmed by the hot hydrogen fluoride from the preheater.
