OSTI ID:6770419
A novel fuel slurry is claimed comprising a mixture of finely ground coal constituting 65 to 70 percent of the fuel, water, a wetting/dispersing agent for the coal constituting 0.5 to 5 percent of the fuel and for stabilizing the fuel slurry a suspending agent which is a clay such as attapulgite clay in the dry, pregelled or predispersed form. Other clays can be montmorillonate clay. If the coal slurry is to be used immediately the clay or other gelling agent is not necessary to maintain suspension stability.
