The motion of a strong line thermal in an unstratified atmosphere is modeled to estimate a bound for its capability to life firebrand particles. It is found that the maximum height of a viable firebrand is roughly proportional to the square root of thermal strength. The…

Spontaneous combustion is thought to be a cause of many of the fires which occur in areas such as peat bogs or dry snags. The theories of spontaneous heating are presented, along with a discussion of possible ignition mechanisms in both wood-chip and hay fires. The physical…
