One of the most important factors in testing the performances of flame-proof enclosures is a pressure piling phenomenon.
This paper describes some experimental results pertinent to the pressure piling phenomena. The significant results obtained are as follows
(1) With the gas concentration of approximately 10%, the maximum piling pressure is recorded.(2) When the gas concentration as low as 6.5%, the piling pressure rises up to such a high value that can not be reached in enclosures with no partition.(3) In many caces, both the piling pressure and the pre-pressure trend to increase with the distance between the ignition position and the partition plate.(4) The piling pressure rises as the opening diameter decreases. The maximum pressure in chamber V1 is in contrast with the piling pressure.(5) The piling pressure may be influenced by the diameter ratio of the opening to the enclosure.(6) When the flame-proof enclosure is divided into three or more compartments by partition plate, the accumulated pressure piling phenomena of higher explosion pressure can be observed.
