Process and device for determining the quantity of an explosive gas mixture to be introduced into the processing chamber (1, 2, 5) of an installation for treating materials (3a or 3b) by temperature and pressure surges in function of the volume of material (3 or 3a) present in the chamber (1, 2, 5). A predetermined minimal quantity of gas or gas mixture is admitted to the closed chamber (1, 2, 5) charged with material (3 or 3a). A signal related to the volume of material (3 or 3a) present in the chamber (1, 2, 5) is derived from the difference (P) between the initial pressure (P0) and the filled pressure (Px). The subsequent quantity of explosive gas mixture to be introduced is determined from said signal. |
