OSTI ID:7301629
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 an emulsifier, which is capable of forming a thixotropic water external-oil high internal 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 /sup 1///sub 4/ inch. The slurry is injected through lances into a blast furnace, the lances may provide concentric streams of slurry and steam. The slurry may also be used in other fuel burning furnaces such as boilers, cement kilns, etc. 12 claims.
