Fire risk of dripping flame: Piloted ignition and soaking effect
The dripping of thermoplastic fuels is a significant fire hazard, but the complex dripping-
ignition process is still not fully understood. In this work, we investigate the ignition capability
of continual polyethylene drips with the size of 2.6–4.6 mg and the frequency of 0.3–1 Hz.
These flaming drips land on four groups of materials, cardstock papers (> 0.1 mm), thin
papers (≤ 0.1 mm), cotton, and porous mineral materials. For igniting cardstock papers, the
minimum drip number decreases with the drip size and frequency, and the ignition time …
