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.

Removal of mercury emissions

A system for removing gaseous pollutants, such as mercury from flue gases of a solid-fueled furnace (), includes a sorbent mill () that receives superheated steam and a sorbent (), such as activated carbon, in a partially agglomerated state, that processes the sorbent () by de-agglomerating and comminuting the sorbent (). An educator () transports the processed sorbent () to a distributor () that injects it into the flue gases at a contact location having a temperature between 500&#xb0; F. and 900&#xb0; F., whereupon the sorbent () adsorbs mercury from the flue gas. A particle collection device () removes the processed sorbent () having adsorbed mercury, from the flue gas.
