Slurry fuel comprised of a heat treated, partially dewatered sludge with a particulate solid fuel and its method of manufacture

摘要

An improved pumpable fuel composition is provided comprising in major proportion a particulate solid fuel and in minor proportion sewage sludge, the improvement wherein said sewage sludge comprises from about 90 to 98 percent by weight of water and which sewage sludge has been subjected to heat treatment at a temperature in the range of from about 150° to 500° F. and subjected to pressures sufficient to both maintain the water content of the heat treated sewage sludge within the range of from about 90 to 98 percent by weight and to effect a lower viscosity for the sewage sludge upon return of the sewage sludge to ambient conditions. A method for the production of the improved fuel composition is also provided.
