THE METHOD OF MAKING A FUEL BRIQUETTE THAT COMPRISES WETTING SOLID CARBONACEOUS FUEL PARTICLES WITH AN AQUEOUS SOLUTION OF A WETTING AGENT FOR CARBONACEOUS MATERIALS, MIXING THE WET PARTICLES WITH CIRCA 1-2% BY WEIGHT OF AN AQUEOUS. EMULSION OF THE BITUMINOUS COMBUSTIBLE DIVIDED TO COLLOIDAL FINENESS, THE TOTAL WATER IN THE FUEL AT THIS STAGE APPPROXIMATING 10-12% BY WEIGHT, DEAERATING THE MIXTURE UNDER LIGHT VACUUM AT A TEMPERATURE IN THE RANGE FROM ATMOSPHERIC TO ABOUT 90* C., EXTRUDING THE DEAERATED MASS, FORMING THE EXTRUSION MASS INTO A SHEET OF UNIFORM THICKNESS WITH PRESSURE, MOLDING THE SAID SHEET THEREBY DIVIDED IT INTO SECTIONS OF BRIQUETTE SHAPE UNDER HEAVY PRESSURE, AND DRYING IT WITH MODERATE AND SUSTAINED HEAT.
