Abstract

An elongate apparatus is disclosed and comprises a material passage and one or more fluid passages. The material passage receives material therethrough. The one or more fluid passages are in fluid communication with the material passage. The material passage and the one or more fluid passages extend substantially parallel throughout the apparatus. A method comprises transferring material in a material passage and further comprises injecting a fluid into the material passage via one or more injection points located along a length of the material passage.

First claim

We claim:

1. An elongate apparatus comprising:
a material passage to receive material therethrough;
at least two fluid passages in fluid communication with the material passage by a plurality of injection points; and
an exterior covering surrounding the material passage and the at least two fluid passages, wherein
the plurality of injection points are configured to allow a fluid to pass from the at least two fluid passages to the material passage, wherein the plurality of injection points comprises a plurality of valves,
the material passage and the one or more fluid passages extend substantially parallel throughout the apparatus,
each valve of the plurality of valves has a total length defined between a first end and a second end opposite with respect to the first end, and
the total length of each valve is positioned between the material passage and one fluid passage of the at least two fluid passages such that the first end of each valve terminates at the material passage and the second end of each valve terminates at the one fluid passage of the at least two fluid passages.

2. The apparatus of claim 1 , wherein fluid is introduced from the at least two fluid passages to the material passage.

3. The apparatus of claim 1 , wherein the plurality of valves comprises at least one of a non-return valve, a check valve, a clack valve, a one-way valve, and/or a nozzle.

4. The apparatus of claim 1 , wherein the plurality of injection points are perpendicular to the material passage such that the fluid may enter the material passage at about a 90 degree angle relative to a flow of the material in the material passage.

5. The apparatus of claim 1 , wherein the plurality of injection points are positioned such that the fluid may enter the material passage in a range of about a 30-degree angle to about a 60-degree angle relative to a flow of the material in the material passage.

6. The apparatus of claim 1 , wherein the exterior covering, surrounding the material passage and the at least two fluid passages, extends along a length of the apparatus.

7. The apparatus of claim 1 , further comprising:
a fluid source in fluid communication with at least one of the at least two fluid passages, the fluid source supplying the fluid through the at least two fluid passages and into the material passage.

8. An elongate apparatus comprising:
a material passage to receive material therethrough;
at least two fluid passages in fluid communication with the material passage via a plurality of injection points;
the plurality of injection points configured to allow a fluid to pass from the at least two fluid passages to the material passage, wherein the plurality of injection points comprises a plurality of valves; and
an exterior covering surrounds the material passage and the at least two fluid passages,
wherein the material passage and the at least two fluid passages extend substantially parallel throughout the apparatus, each valve of the plurality of valves has a total length defined between a first end and a second end opposite with respect to the first end and the total length of each valve is positioned inside the exterior covering surrounding the material passage and the at least two fluid passages.
