Removal of mercury emissions

A system for removing gaseous pollutants, such as mercury from flue gases of a solid-fueled furnace (17), includes a sorbent mill (34) that receives superheated steam and a sorbent (28), such as activated carbon, in a partially agglomerated state, that processes the sorbent (28) by de-agglomerating...

Beschreibung
Zusammenfassung:	A system for removing gaseous pollutants, such as mercury from flue gases of a solid-fueled furnace (17), includes a sorbent mill (34) that receives superheated steam and a sorbent (28), such as activated carbon, in a partially agglomerated state, that processes the sorbent (28) by de-agglomerating and comminuting the sorbent (28). An educator (35) transports the processed sorbent (28) to a distributor (36) that injects it into the flue gases at a contact location having a temperature between 500° F. and 900° F., whereupon the sorbent (28) adsorbs mercury from the flue gas. A particle collection device (24) removes the processed sorbent (28) having adsorbed mercury, from the flue gas.
