Patent ID: 8408148

Claim:
A method of increasing the efficiency of a combustion process which comprises adding bentonite to a flame, fireball or burner region combustion zone during combustion thereof in an amount sufficient to increase the efficiency of combustion compared to when bentonite is not added, wherein the bentonite comprises the following characteristics as determined by X-ray fluorescence: Component Wt % SiO2 from about 60 to about 66% Al2O3 from about 19 to about 22% Fe2O3 from about 3 to about 4% TiO2 from about 0.1 to about 0.2% P2O5 from about 0.03 to about 0.08% MgO from about 1.7 to about 2.5% CaO from about 0.4 to about 1% Na2O from about 1.3 to about 2.5% K2O from about 0.3 to about 0.6% BaO up to about 0.05% SrO from about 0.01% to about 0.04% V2O5 less than about 0.03% NiO from about 0.005% to about 0.02% MnO less than about 0.01% Cr2O3 less than about 0.01% Loss, fusion up to about 15%.
