Energy in a Ton of Coal - The Physics Factbook

The amount of energy produced by a ton of coal is largely dependent upon the type of coal being burned. There are four major categories of coal, each differing in composition and age. Lignite, also known as brown coal, is the least valuable of the four. Lignite is primarily used as fuel for steam to generate electric power.

Spontaneous combustion - Wikipedia

Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.
