Abstract: A method of enhancing the combustion of solid fuel/water slurries by the addition of about 100 to 5,000 ppm of a stable water-soluble explosive, which will detonate early in the combustion process, thereby producing a secondary dispersion of fuel particles, and an 80-65% coal/20-35% water composition suitable for secondary dispersion during combustion containing about 100-5,000 ppm of a water-soluble explosive, preferably selected from at least one member of a group consisting of picric acid; alkali picrates, such as ammonium picrate, sodium picrate, potassium picrate, calcium picrate, etc., and heavy metal picrates, such as iron picrate, lead picrate, zinc picrate, etc.; guanidine and nitroguanidine. The addition of the explosive may be made to the water of make up of the slurry or may be added to the formed slurry.
