Fuel pellet briquettes from biomass and recovered coal slurries

Abstract

The invention makes burnable renewal fuel (RF) briquettes from recovered coal from coal slurry ponds, biomass, and a binder. The briquettes may be augmented with one or more of recovered environmental burnable fraction from municipal solid waste (MSW), agricultural livestock waste, lumber processing residue, solid wood waste material, agricultural by-products and crops, and like burnable waste material. Accordingly, the method for making burnable renewal fuel (RF) briquettes includes the steps of recovering coal from coal slurry ponds; recovering biomass; adding a binder to said recovered coal and said biomass; and forming solid burnable RF fuel briquettes therefrom.

1 . Method for making burnable renewal fuel (RF) briquettes, which comprises the steps of: 
 (a) recovering coal from coal slurry ponds;    (b) recovering biomass;    (c) adding a binder to said recovered coal and said biomass; and    (d) forming solid burnable RF fuel briquettes therefrom.    
   
   
       2 . The method of  claim 1 , wherein said biomass is one or more of a burnable cellulose fraction of municipal solid waste (MSW), animal waste, agricultural livestock waste nutrients, wood, bagasse, or agricultural crop waste.  
   
   
       3 . The method of  claim 2 , wherein said biomass is one or more of manure, litter, wood shavings, rice hulls, straw, mill and timber harvesting residue, pre-commercial thinning lumber, slash, brush, wooden pallets, crates, dunnage, manufacturing and construction wood wastes, landscape and right-of-way tree trimmings, bagasse, orchard tree crops, vineyard, grain, legumes, or sugar.  
   
   
       4 . The method of  claim 1 , wherein said binder is a hydrocarbon.  
   
   
       5 . The method of  claim 4 , wherein said hydrocarbon is one or more of wood tar, asphalt, or starch.  
   
   
       6 . The briquette made according to the process of  claim 1 .  
   
   
       7 . The briquette made according to the process of  claim 2 .  
   
   
       8 . The briquette made according to the process of  claim 3 .  
   
   
       9 . The briquette made according to the process of  claim 4 .  
   
   
       10 . The briquette made according to the process of  claim 5.
