## Abstract

A reactor for reducing sulfur oxides emissions in a combustion process in which flue gases containing entrained fuel and sorbent particles are humidified so that the sulfur oxides are absorbed on the sorbent particles to reduce the discharge of the sulfur oxides into the environment.

## Claims

### Claim 1

A reactor for treating a gaseous product, said reactor comprising;
a vessel having two opposed walls;
two plenums respectively associated with said opposed walls for receiving said gaseous product;
a plurality of louvers extending through each of said opposed walls and respectively aligned with said plenums for introducing said gaseous product into the interior of said vessel;
means for introducing water into an area of said vessel between said opposed walls and their respective louvers to humidify said gaseous product;
two additional plenums respectively associated with said opposed walls for receiving additional gaseous product, said additional plenums being located at a different level of said vessel than said first-mentioned plenums; and a plurality of inlet openings extending through each of said opposed walls and respectively aligned with said additional plenums for introducing said additional gaseous product into the interior of said vessel at a different level than the level of introduction of said first-mentioned gaseous product; and
an additional plenum associated with the roof of said vessel for receiving additional gaseous product and an inlet opening formed through said roof for introducing said latter additional gaseous product from said roof downwardly into said vessel.

### Claim 2 (depends on 1)

The reactor of claim 1 wherein said latter additional gaseous product is discharged over said water-introducing means.

### Claim 3 (depends on 1)

The reactor of claim 1 wherein said louvers function to break said gaseous product into a plurality of streams to promote said humidification and to direct said gaseous product into said vessel and away from their respective opposed walls.
