Clean coal electrical generation

Abstract

The invention produces a mechanism and method to clean coal of contaminates/pollutants such as sulfur, mercury, silica, and others, for use in a coal fired electrical generator. The mined coal is first ground to a mesh size and is subjected to a vertical separator which separates contaminates/pollutants from the coal. The now cleaned coal is ground to a smaller mesh size and injected into the boiler of the electrical generator. In some embodiments, the cleaned coal is formed into solids for transport to the coal fired electrical generator.

What is claimed is: 
     
         1 . A coal fired generator operation comprising the steps of:
 a) grinding coal to a first coarseness to form a first ground coal;   b) separating contaminates from the first ground coal using a particle density vertical separator to form a clean ground coal by precipitating the contaminates;   c) grinding the clean ground coal into a second coarseness to form a second ground coal; and,   d) injecting the second ground coal into a boiler adapted to generate electricity.   
     
     
         2 . The coal fired generator according to  claim 1 , wherein the steps of grinding coal to a first coarseness, separating contaminates from the first ground coal, and grinding the clean ground coal into a second coarseness are all performed within a single housing. 
     
     
         3 . The coal fired generator according to  claim 1 , further including the step of forming the clean ground coal into solids having at least four cubic inches of clean ground coal. 
     
     
         4 . The coal fired generator according to  claim 3 , wherein the step of forming the clean ground coal into solids includes the step of forming the clean ground coal into pellet shape. 
     
     
         5 . The coal fired generator according to  claim 4 , further including the step of transporting the clean coal pellets to the site for grinding the clean ground coal to the second ground coal. 
     
     
         6 . The coal fired generator according to  claim 5 , wherein the step of transporting the clean coal pellets includes the step of loading the clean coal pellets into a rail-road car. 
     
     
         7 . A mechanism to clean coal of contaminates comprising:
 a. a container holding mined coal;   b. a first grinder receiving the mined coal and adapted to grind the mined coal to a first coarseness, forming a first ground coal; and,   c. a vertical particle separator receiving the first ground coal and adapted to separate contaminates from the first ground coal to form clean ground coal.   
     
     
         8 . The mechanism to clean coal of pollutants according to  claim 7 , further including a mechanism adapted to form the clean ground coal into solids having at least four cubic inches of clean ground coal. 
     
     
         9 . The mechanism to clean coal of pollutants according to  claim 8 , wherein the mechanism adapted to form the clean ground coal into solids forms the clean ground coal into pellet shape solids. 
     
     
         10 . The mechanism to clean coal according to  claim 9 , further including a conveyor mechanism transporting the pellet shaped solids into a rail-road car. 
     
     
         11 . A mechanism used in conjunction with a coal fired generator comprising:
 a) a container holding mined coal;   b) a first grinder receiving the mined coal and adapted to grind the mined coal to a first ground coal;   c) N separation systems, each of said separation systems receiving said first ground coal in an cascading series from the prior separation system such that each separation system withdraws a specified size of said first ground coal and delivers said specified size to an associated vertical particle separator such that said vertical particle separator separates contaminates from the first ground coal to produce a clean ground coal.   
     
     
         12 . The mechanism used in conjunction with a coal fired generator according to  claim 11 , further including a compaction mechanism adapted to form the clean ground coal from the separation systems into solids having at least four cubic inches of clean ground coal. 
     
     
         13 . The mechanism used in conjunction with a coal fired generator according to  claim 12 , wherein the compaction mechanism adapted to form the clean ground coal into solids forms the clean ground coal into pellet shape solids. 
     
     
         14 . The mechanism used in conjunction with a coal fired generator according to  claim 13 , further including a conveyor mechanism transporting the pellet shaped solids into a rail-road car. 
     
     
         15 . The mechanism used in conjunction with a coal fired generator according to  claim 12 , further including:
 a) a second grinder receiving the clean ground coal and creating coal of a second size to form second ground coal;   b) a blending mechanism for mixing Blending the second ground coal into an airstream; and,   c) an injector applying the airstream into a boiler of the coal fired generator.
