Benefits of technology
The present invention provides a paste that can be mixed with bio-mass fiber to make it hydrophobic. Additionally, the invention enhances the pellets or briquettes by adding other waste materials like cellulose, waste foam, or paper. This not only removes and utilizes combustible materials from household and industrial waste streams but also adds value to these waste products and reduces the carbon foot-print of the coal paste-derived products.
Problems solved by technology
However, the use of lump coal is difficult in noncommercial applications while the use of powdered or pulverized coal presents inhalation and explosion hazards.
However, these liquid fuels, which are largely petroleum products, are more expensive than coal.
The supplies of petroleum are more limited and are largely located in volatile areas.
Rudolf Diesel, the inventor or the diesel engine, initially studied coal powder as a fuel for his original engine, but handling issues and explosion hazards caused him to abandon the technology.
These technologies have problems with the coal powder falling out of suspension of coal and water or coal and oil.

)
[0064]In describing the preferred embodiment of the present invention, reference will be made herein to FIGS. 1-7 of the drawings in which like numerals refer to like features of the invention.
[0065]The present invention is a coal energy fuel system in a paste composition comprising coal, which may be in the form of a dust, powder, granules, or the like, and may include at least one surfactant, at least one binder and at least one carrier fluid. The paste may include a bio-mass.
[0066]The invention is a coal energy fuel system that utilizes coal in the form of a dust, powder or granule formulated into a paste. The paste comprises anthracite or bituminous coal, dewatered sludge, bio-diesel fuel and a surfactant which may be mixed until a paste is formed. The paste may be a thick viscous fluid such as a semi-liquid colloidal suspension, emulsion, or aggregation which then can be loaded into a cartridge or directly into a screw pump to feed conventional oil furnaces. The paste may pass...

Abstract
The present invention relates to the use of coal to form a paste that can be used as a fuel or incorporated with other fillers to form pellets or briquettes. The paste is formed from crushed or powdered coal mixed in a liquid fuel and may be used as is or may be mixed with a carrier fuel prior to combustion or it could be mixed with other biomass fillers to produce a solid fuel.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to the use of coal in devices that use liquid fuel so the use of liquid fuels is partially offset by the use of coal. More particularly, the invention relates to using a paste composed of coal, binder, surfactant and the liquid fuel which may be used in place of fuel which is entirely liquid such as gasoline, diesel, oil, and ethanol or converted into a solid pellet. The paste is formed from crushed or powdered coal mixed in a liquid fuel and may be used as is or may be mixed with a carrier fuel prior to combustion or it could be mixed with other biomass fillers to produce a solid fuel.[0003]2. Description of Related ArtDefinitions[0004]As used herein, “paste” is a thick viscous fluid such as a semi-liquid colloidal suspension, emulsion, or aggregation.[0005]As used herein, “gel” is a solid three-dimensional network that spans the volume of a liquid medium and incorporates islands of solid ...
