Abstract

An emissions reduction system comprising an emission gas inlet for receiving emissions-containing gas, and an emissions reducing device for reducing emissions contained in the emissions-containing gas. The emissions reducing device is coupled at a first end thereof to the emission gas inlet and an emission gas outlet is coupled at a second end of the emissions reducing device for releasing emissions-reduced gas. The emissions reducing device comprises: a torturous fluid channel, lava material displaced within the torturous fluid channel wherein the lava material is located within a set of self contained containers within the emissions reducing device.

Claims

1. An emissions reduction system comprising, in combination:

inlet means for receiving emissions-containing gas;

emissions reducing means coupled at a first end thereof to said inlet means for reducing emissions contained in said emissions-containing gas;

said emissions reducing means comprising;

a fluid channel;

a set of self contained containers spaced apart from one another and located within said fluid channel;

each of said self contained containers having an inlet side partially obstructed to the flow of said emissions-containing gas and an outlet side partially obstructed to the flow of said emissions-containing gas so as to force said emissions-containing gas to follow a torturous flow path when flowing from said inlet side to said outlet side;

lava material displaced within said set of self contained containers;

wherein said lava material comprises lava material having the following physical and chemical properties;

and

outlet means coupled at a second end of said emissions reducing means for releasing emissions-reduced gas.

2. The system of claim 1 wherein said lava material located within said sets of self contained containers is packed to a pre-selected loading having pre-selected mass and surface area ratios of said lava material.

3. The system of claim 2 wherein said pre-selected lava material has a screened particle size of substantially 3/16", has a weight to volume ratio of substantially 1:

1.2, and is packed into said self contained containers to a compaction factor of substantially 85%.

4. The system of claim 3 wherein said set of self contained containers is a plurality of disc shaped containers.

5. The system of claim 4 wherein said plurality of disc shaped containers comprises at least three containers.

6. The system of claim 1 wherein the surface area of said inlet side is equally divided between a non-obstructed portion and an obstructed portion and wherein the surface area of said outlet side is equally divided between a non-obstructed portion and an obstructed portion.
