Abstract

The results of studies aimed at improving the methods and equipment for the preliminary treatment of lignocellulosic raw materials by means of steam explosion are presented. The scientific basis for the outflow of superheated steam from a reactor in the course of detonation boiling of a liquid is described. Based on theoretical and experimental studies, it is shown that, in order to provide an increase in the efficiency of the steam explosion energy, it is appropriate to mount an aerohydrodynamic grinder (AHG) containing a Laval nozzle at the reactor outlet.
