Patent ID: 6946102

Claim:
An apparatus for removing particulate matter and pollutants from a gas stream comprising, a duct having a gas inlet first end connected to receive a gas stream containing pollutant particles, said duct defining a straight passageway between said first end and a second end that connects to vent particulates into a particulate removal means, said duct having a length and a sorbent material injector means fitted into a duct side at a sorbent introduction site, with said sorbent material injector means having a nozzle end located within the duct that is to pass particles of a sorbent material into, and counter-current to, a flue gas flow, passing through said duct that contains pollutant particles, providing mixed and compacted sorbent material and pollutant particles; a moisture sensor means installed in said duct downstream from said injector means nozzle end to read moisture content of the gas stream containing said mixed and compacted sorbent material and pollutant particles; moisture injector means fitted into said duct downstream from said moisture sensor means and spaced from twenty to thirty feet from said sorbent material injector means nozzle end for injecting water, as a mist, into said gas stream containing said mixed and compacted sorbent material and pollutant particles, which said moisture injector means is connected to a source of water and is operated in response to a sensing, by said moisture sensor means, of a requirement to moisturize said gas stream containing said mixed and compacted sorbent material and pollutant particles to provide a moisture content thereto that is a percentage of from eighteen to twenty percent of saturation, and which said moisture is injected into said mixed and compacted sorbent material and pollutant particles prior to its passage into a removal means; removal means for removing said mixed and compacted sorbent material and pollutant particles.
