✦ Synopsis

The present paper reports the experimental results for ignition characterisitcs of a fuel droplet near the ignitable limit. It is found experimentally that the ignition time increases as the droplet diameter decreases at the region near the ignition limits, and that, over the broad range, ignition occurs more rapidly as the diameter increases if the initial droplet temperature is high. The reason why such pehnomena occur is examined.

A comparison between the results of Faeth and Olson and the present ones is made and the discrepancies discussed. The effect of initial droplet temperature on ignition is examined. The general trends agree with the results of computation obtained previously.

The spontaneous ignition of a premixed silane-oxygen-nitrogen system has been investigated under a variety of conditions. It has been found that the autoignition temperatures are lower than room temperature if the oxygen concentration is extremely low. The spontaneous ignition of silane results from
