Co-Fired Syngas System

Abstract

A method of generating a blended syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a gassifier arrangement. The generated syngas is blended with natural gas to form a blended fuel product that is delivered to a manufacturing facility or a natural gas power plant.

What is claimed is: 
     
         1 . A method of producing a fuel, the method comprising the steps of:
 delivering a feedstock to a gassifier to generate a product syngas; and   blending the product syngas with natural gas to form a blended syngas fuel.   
     
     
         2 . The method of  claim 1 , wherein there is provided the step of delivering the blended syngas fuel to a selectable combination of a manufacturing plant and a natural gas power plant. 
     
     
         3 . The method of  claim 1 , wherein prior to performing said step of blending there is provided the step of cleaning the product syngas. 
     
     
         4 . The method of  claim 1 , wherein prior to performing said step of blending there is provided the step of accumulating the product syngas in a buffer. 
     
     
         5 . The method of  claim 4 , wherein said step of accumulating comprises the steps of:
 first compressing the product syngas; and   storing the compressed product syngas in the buffer.   
     
     
         6 . The method of  claim 5 , wherein there are provided the further steps of:
 releasing the compressed product syngas from the buffer; and   boosting the pressure of the compressed product syngas released from the buffer.   
     
     
         7 . The method of  claim 1 , wherein the feedstock is a selectable combination of an organic compound, a fossil fuel, and a hazardous material. 
     
     
         8 . A method of producing a fuel, the method comprising the steps of:
 operating a pregassifier on a selectable combination of waste heat, syngas, a fossil fuel, and a supplemental fuel;   operating a gassifier to generate a product syngas, by delivering a feedstock to the gassifier; and   blending the product syngas with natural gas to form a blended syngas fuel.   
     
     
         9 . The method of  claim 8 , wherein there is provided the step of delivering the blended syngas fuel to a selectable combination of a manufacturing plant and a natural gas power plant. 
     
     
         10 . The method of  claim 8 , wherein prior to performing said step of blending there is provided the step of cleaning the product syngas. 
     
     
         11 . The method of  claim 8 , wherein prior to performing said step of blending there is provided the step of accumulating the product syngas in a buffer. 
     
     
         12 . The method of  claim 8 , wherein the feedstock is a selectable combination of an organic compound, fossil fuel, and a hazardous material. 
     
     
         13 . A method of producing a fuel, the method comprising the steps of:
 operating a pregassifier on a selectable combination of waste heat, syngas, a fossil fuel, and a supplemental fuel;   operating a gassifier to generate a product syngas, the gassifier having a metal bath, an inductive heat source, and at least one plasma torch to reflect energy off the metal bath;   delivering a feedstock to the gassifier; and   blending a product syngas with natural gas to form a blended syngas fuel.   
     
     
         14 . The method of  claim 13 , wherein there is provided the step of delivering the blended syngas to a selectable combination of a manufacturing plant and a natural gas power plant. 
     
     
         15 . The method of  claim 13 , wherein prior to performing said step of blending there is provided the step of cleaning the product syngas. 
     
     
         16 . The method of  claim 13 , prior to performing said step of blending there is provided the step of accumulating the product syngas in a buffer. 
     
     
         17 . The method of  claim 13 , wherein the feedstock is a selectable combination of an organic compound, a fossil fuel, and a hazardous material. 
     
     
         18 . The method of  claim 13 , where the syngas is cleaned and buffered and compressed before blending with natural gas. 
     
     
         19 . The method of  claim 13 , where the plasma torch operates in any combination of direct acting, indirect acting, AC driven, and DC driven.
