## Abstract

An injection lance assembly for creating a higher degree of turbulence and dispersion of a treating agent into a fluid stream.

## Claims

### Claim 1

An injection lance assembly which can be inserted into a port in ductwork, the lance assembly comprising;
a) a tube for providing particulate flow into a fluid stream within the ductwork;
b) at least two pairs of wings which are deployable within the ductwork and may be inserted through the port with the tube; and
c) means for actuating the wings into a deployed position;
whereby the lance assembly when deployed in the ductwork has a larger diameter than the port.

### Claim 2 (depends on 1)

The assembly of claim 1 wherein the means for actuating the wings into a deployed position comprises a cable actuator.

### Claim 3 (depends on 1)

The assembly of claim 1 wherein the tube further comprises a tip region, the tip region providing the means for actuating the wings into a deployed position.

### Claim 4 (depends on 1)

The assembly of claim 1, wherein the means for actuating the wings into a deployed position comprises a punch rod.

### Claim 5 (depends on 1)

The assembly of claim 1, wherein the wings pivot radially relative to the tube.

### Claim 6 (depends on 1)

The assembly of claim 1, wherein the wings are attached to the tube.

### Claim 7 (depends on 1)

The assembly of claim 1, further comprising a shroud defining a channel with the tube displaceable therethrough, the least two pairs of wings being attached to the shroud.

### Claim 8 (depends on 1)

The assembly of claim 1, wherein the tube comprises a plurality of tubes.

### Claim 9 (depends on 1)

The assembly of claim 1, wherein the tube includes a plurality of apertures along the length of the tube.

### Claim 10 (depends on 9)

The assembly of claim 9, wherein each of the plurality of apertures is at an axial location corresponding to the at least two pairs of wings.

### Claim 11 (depends on 1)

The assembly of claim 1, further comprising a means for retracting the wing through the port.

### Claim 12 (depends on 11)

The assembly of claim 11, wherein the means for retracting uses the same structure as the means for actuating the wings into a deployed position.
