摘要：

An investigation was conducted on the effect of initial pressure on lycopodium dust explosions in a 26 I test chamber. Maximum explosion pressures and maximum rates of pressure rise were measured over a range of initial pressures from 0.87 bar to 2.0 bar. Spark ignition was used for all tests. For each initial pressure, the peak values of maximum explosion pressure and maximum rate of pressure rise were found to occur at a fuel equivalence ratio of 4.5. When considered as a function of initial pressure, the peak explosion pressure values displayed a linear and proportional variation. © 1990.
