Explosion parameters.
The more representative values of: experimental pressure of explosion, medium and maximum speed of increase pressure of the sample examined, are obtained by direct powder dispersion in the air in the equipment of the experiment. The experiment has been done under ambient temperature and atmospheric pressure, and has allowed outlining its course with the powder concentration. The maximum explosion pressure value delta P, medium speed (dP/dt)media and maximum (dP/dt)max of increase pressure for the sample are cited in the following table.
| SAMPLE | delta P (bar) | (dP/dt)media [bar/s] | (dP/dt)max [bar/s] |
| DDH | 6,2 | 78 | 189 |
Applicant's summary and conclusion
- Conclusions:
- The examined sample, according to the maximum speed of increase pressure
obtained, can be classify in order to the technique Iiterature as betonging to de class
