Abstract
A coal pellet which disintegrates in the presence of excess heat and comprises coal particles, water soluble binder and water. The binder is first dissolved in water and then coal particles are blended with the aqueous binder solution. The blend is agitated until pellets are formed and then the pellets are coated with a water resistant film. The coal pellets have water entrained therein which is converted to a gaseous form when the pellets are subjected to heat thereby facilitating the heat induced bursting of the pellets to free the coal particles for more efficient burning.
