Coal derived/aqueous fuel system and method of manufacture
First Claim
1. A fluidic, substantially non-polluting fuel system comprising a liquid/solid mixture, including a portion of a particulate coal char, dispersed in an amount of water effective to produce a transportable composition wherein said particulate coal char is treated with a sealant effective to reduce absorption of water.

Abstract
Coal char produced by the pyrolytic destructive thermal distillation of coal in the absence of oxygen is ground, sized and then admixed in suitable portions with water to form a fluidic, liquid-solid fuel system comprising a nonpolluting, stable, transportable, high energy fuel. The fuel system can be fired directly or the char can be separated and fired as a solid fuel. The liquid organic fraction obtained from the low boiling fractions derived from the pyrolysis of coal is used as a fuel or as a feed stock.

25. A method of firing a combustion system comprising the steps of:
-
(a) injecting a combustible amount of a fuel composition into a combustion chamber wherein said fuel composition is selected from a group consisting of (1) a fluidic fuel composition comprising a solid/liquid admixture including a portion of a particulate coal char material dispersed in an amount of water effective to produce a transportable fuel wherein said particulate coal char is treated with a sealant effective to reduce absorption of water; (2) a solid material of particulate coal char obtained from removal of at least a portion of the solid in said solid/liquid admixture; and (3) a fluidic fuel composition comprising a solid liquid admixture including a portion of a particulate coal char material dispersed in an amount of a water/liquid organic mixture obtained from pyrolysis of coal; (b) admixing said combustible amount of said fuel with sufficient oxygen to support substantially complete combustion, thus producing a substantially, totally combustible mixture; (c) heating said combustible mixture to the ignition point; (d) sustaining the combustion within said chamber; and (e) exhausting the combustion by-products from the chamber. - View Dependent Claims (26)
