Abstract
The present invention improves flame combustion of liquid carbonaceous fuels by the preparation and use of a fuel additive comprising a finely-divided particulate hydrated compound in stable suspension in a liquid vehicle. The median major dimension of the primary particles of hydrated compound is preferably less than 10 microns. When employed at a level of from about 200 to about 5000 parts per million, the additive can improve the efficiency of combustion and reduce particulate emissions for flame combustion of liquid carbonaceous fuels, especially residual grades of fuel oil.
