He doesn't seem to get the simple concept of power density...

Not an expert, but boiled linseed oil produces heat when it polymerizes. If a rag is spread out on a nonflammable surface the heat will not be able to reach a point of combustion in most cases. If the rag is wadded up tightly, the internal heat build up may rise to the point of combustion.
To be specific, power equals the energy created by the polymerization of boiled linseed oil. The density of this energy causes it to increase into a high enough temperature causing combustion.
Please realize that this is my understanding of the term and I may be totally wrong. It has helped me in preventing flaming rags in my shop and work spaces.
Like George says, best to not leave them laying around.
