Patent ID: 8578965

Claim:
A sorbent supply system comprising: at least one sorbent supply manifold, each sorbent supply manifold comprising: a main body having a top and a bottom, the main body having a tapered end located at the bottom end of the main body; an inlet pipe, the inlet pipe being connected to the tapered end of the main body; an impact plate, the impact plate being located at the top end of the main body directly opposed to the tapered end of the main body and being designed to hold therein two or more distribution vanes; two or more distribution openings, the distribution openings being formed in the tapered end of the main body; and two or more distribution pipes, wherein one distribution pipe is connected in an air tight manner to a respective distribution opening, wherein the two or more distribution vanes of the impact plate are designed to separate and distribute powdered sorbent to at least one distribution opening and wherein the two or more distribution vanes and the two or more distribution openings are arranged in a staggered fashion, and at least two sorbent injection lance devices, each sorbent injection lance device comprising: an inner supply pipe; an outer supply pipe; and a sleeve pipe, wherein the lance device has a first end where one end of both the inner supply pipe and the outer supply pipe are flat and flush with one another and a second ends of the inner supply pipe and outer supply pipe that are angled and are located opposite the flats ends, wherein the angled end of the inner supply pipe extends beyond the angled end of the outer supply pipe, wherein the sleeve pipe has two flat ends with the first flat end of the sleeve pipe being located nearest to the flat ends of the inner and outer supply pipes, the first flat end having a flange for attaching the lance device to a surface, wherein the second flat end of the sleeve pipe is located nearest to the angled ends of the inner and outer supply pipes where the outer supply pipe extends beyond the second flat end of the sleeve pipe, wherein the inner supply pipe is has a smaller diameter than the outer supply pipe, which has a smaller diameter than the sleeve pipe, wherein the inner supply pipe is concentrically located within the outer supply pipe so as to create a first annular region between the external surface of the inner supply pipe and the interior surface of the outer supply pipe, wherein the outer supply pipe is concentrically located within the sleeve pipe so as to create a second annular region between the external surface of the outer supply pipe and the interior surface of the sleeve pipe, wherein at least one of the first or second annular regions are supplied with a powder sorbent, and wherein each of the at least two sorbent injection lance devices are in communication with one distribution opening in the at least one sorbent supply manifold.
