Method of reducing air pollutant emissions from combustion facilities

Abstract

The present invention relates to a method of reducing air pollutant emissions such as dioxin or mercury from combustion facilities including furnaces and electricity generation equipment. More particularly, the invention relates to a method of reducing the amount of air pollutants such as dioxin or mercury from combustion facilities by inputting the precursor of nano-particles such as titanium dioxide photo-catalyst or reactive potassium iodide into the combustion facilities as a mixture with air or fuel supply of the combustion facilities, thereby allowing nano-particles to be synthesized during the combustion process and such synthesized nano-particles to absorb, decompose and adhere the air pollutants in the combustion facilities.

1 . A method of reducing air pollutant emissions from combustion facilities, wherein the air pollutant emissions from combustion facilities or their precursors are removed by utilizing nano-particles or their precursors.  
     
     
         2 . The method according to  claim 1 , wherein the nano-particles or their precursors are inputted into an specific location of the combustion facilities, wherein the specific location is the location where said air pollutant emissions or their precursors are generated.  
     
     
         3 . The method according to  claim 2 , wherein the precursors of the nano-particles are inputted into the combustion facilities and then converted into nano-particles through in situ formation in the combustion facilities during the combustion process.  
     
     
         4 . The method according to  claim 3 , wherein the precursors of the nano-particles are inputted into the combustion facilities in conjunction with air or fuel supply for the combustion facilities.  
     
     
         5 . The method according to  claim 3 , wherein the precursors of the nano-particles are inputted into the combustion facilities in the state of gas or liquid.  
     
     
         6 . The method according to  claim 5 , wherein the precursors of the nano-particles are sprayed into a combustion chamber of said combustion facilities.  
     
     
         7 . The method according to  claim 1 , wherein the nano-particles are titanium dioxide photo-catalyst nano-particles or reactive potassium iodide nono particles.  
     
     
         8 . The method according to  claim 1 , wherein the air pollutant emissions are heavy metals which include mercury, cadmium, and arsenic.
