Abstract
A method of preparing a stabilized fuel slurry is disclosed wherein a petroleum fuel oil is mixed with 'run of the mine' coal and with a polysaccharide emulsifier capable of forming water internal-oil high external phase emulsion. The slurry is mechanically mixed to comminute the coal to produce a stabilized fuel slurry with coal particles having diameters as large as about 1/4 inch. The slurry is injected through lances into a blast furnace, the lances provided concentric streams of slurry and steam. The slurry may also be used in other fuel burning furnaces such as boilers, cement kilns, etc.
