The present invention is applicable to the preheating process of distillate especially to those distillates contained deposit capable of separating out. For example the pipe column type preheater is ordinarily adopted for prehesting dilute alcohol contained nitrocotton, and the esplosion will occur while long time heating of nitrocotton. Said invention uses a nozzle to eject the heating medium for directly preheating and the preheating temp is controlled through the controlling of heating medium, so that the technique is simplified, the harm due to deposite is avoided and the energy consumption is lowered.
