Abstract
A fluid fuel mixture is formed of a suspension of a pulverized solid fuel and of at least one aqueous phase representing from 15 to 40 percent of the mixture before an optional incorporation of an additive. The mixture can comprise, as a supplement to particle-size fractions of the pulverized solid fuel, or as a replacement for some of these fractions, additional particle-size fractions produced from heavy petroleum residues of a natural or synthetic origin which are solid at the temperature at which the invention is practiced. The fluid fuel mixture may be used, for example, in boilers, industrial furnaces, or gasification reactors.
