Abstract
The invention provides a method of increasing the efficiency of a combustion process by adding bentonite to the flame, fireball or burner region combustion zone of the combustion process. Also provided is a combustion chamber that includes a bentonite feed system and a fuel additive composition of a bentonite such as sodium bentonite having a particle size range that may be employed in the method of the present invention.
