Fuel and emissions reduction power plant design using Oxygen for combustion and flue gas recirculation to minimize Carbon Dioxide and NOx emissions

Abstract

Power/process boiler modifications to use direct Oxygen input to burn the Carbon based fuel in a Nitrogen deficient atmosphere created by flue gas recirculation. This will result in a substantial reduction in fuel consumption and less Carbon Dioxide plus a near elimination of NOx in the flue exhaust released to the atmosphere. Both substances contribute to the Greenhouse effect and Global Warming and widespread use of his concept would help to reduce Global Warming and also reduce the usage and depletion of Carbon based fuels.

1 . Original design or modifications to existing power systems to incorporate this patent application will have the following benefits: 
 Direct Oxygen feed to provide the combustion of the Carbon based fuel will result in a higher flame temperature than using atmospheric air for the source of Oxygen. For a given quantity of fuel, the necessary BTU output can be achieved with a reduced quantity of fuel. This higher temperature will further heat the bypassed flue gases to bring the resultant mixture to the desired temperature needed to transfer heat energy to the production of steam or other process heating. The reduced quantity of Carbon based fuel will also result in the release of considerably less Carbon Dioxide, an undesirable Greenhouse gas.    
   
   
       2 . The process of initially charging the boiler/heater combustion chamber with a non-Nitrogen atmosphere will preclude the formation of significant quantities of NOx compounds. NOx gases are an undesirable Greenhouse stimulating gas. Power producers and manufacturers are generally charged or monitored by the EPA to limit their release to the atmosphere.
