Abstract
A burner is operated by continuously feeding into its combustion zone while combustion is occurring therein, (a) a middle distillate burner fuel with which has been blended in any sequence or combination a minor combustion improving amount of fuel-soluble manganese polycarbonyl compound(s), and (b) a total amount of air above 100% of the stoichiometric amount required for complete combustion of all fuel being introduced into said zone but which is below 105% of such stoichiometric amount. Preferably at least alkali or alkaline earth metal-containing detergent and fuel-soluble dispersant have also been blended into the fuel being used. The efficiency of operation of blue and yellow burners is thereby improved, and emissions such as carbon monoxide and nitrogen oxide can be reduced as compared to operation of the same burner on the same unadditized base fuel.
