REMOVAL OF MERCURY EMISSIONS |
摘要 |
A method for more efficiently removing pollutant gases from flue gases of a solid-fueled steam generator includes storing a silo a carbonaceous sorbent in a powdered form; extracting a superheated steam from a superheated steam source; and reducing a temperature, pressure and moisture content of the superheated steam to provide a processed steam of a desired pressure, temperature and moisture content. The method further includes providing a sorbent mill receiving the carbonaceous sorbent and the processed steam, wherein the sorbent mill is operable to de-agglomerate and comminute the carbonaceous sorbent using the processed steam to provide a processed sorbent. Further the method includes injecting the processed sorbent into the flue gases at a desired location in the solid-fueled steam generator thereby adsorbing the pollutants therefrom; and collecting and thereby remove the carbonaceous sorbent from the flue gas fluidly downstream from the desired location. |

1. A method for more efficiently removing pollutant gases from flue gases of a solid-fueled steam generator; the method comprising:
storing a silo a carbonaceous sorbent in a powdered form; extracting a superheated steam from a superheated steam source; reducing a temperature, pressure and moisture content of the superheated steam to provide a processed steam of a desired pressure, temperature and moisture content; providing a sorbent mill receiving the carbonaceous sorbent and the processed steam, wherein the sorbent mill is operable to de-agglomerate and comminute the carbonaceous sorbent using the processed steam to provide a processed sorbent; injecting the processed sorbent into the flue gases at a desired location in the solid-fueled steam generator thereby adsorbing the pollutants therefrom; and collecting and thereby remove the carbonaceous sorbent from the flue gas fluidly downstream from the desired location. |
