Abstract

A fluid type, gel/wax/paraffin type, or mechanical type harmonic balancer for built-in or retrofit use with an atomizer of a SDA flue gas desulfurization system for reduced atomizer vibration within or outside of the atomizer's harmonic range is provided herein. Also provided, is a method of using the built-in or retrofit harmonic balancer with an atomizer of a SDA flue gas desulfurization system to decrease atomizer vibration within or outside the atomizer's harmonic range, to increase atomizer on-line service hours, decrease atomizer maintenance requirements, and to decrease atomizer associated costs.

First claim

The invention claimed is:

1. A spray dryer absorber atomizer with a balancer comprising:
a distributor housing operable to distribute an absorbent liquid or slurry within a spray dryer absorber vessel; and
an atomizer disk removably attached to the distributor housing comprising
an annular channel;
at least two ports fluidly connected to the annular channel; and
a substance, member, or combination with non-Newtonian characteristics partially filling the annular channel.

2. The atomizer of claim 1 , wherein each of the at least two ports are sealed by screws threadedly engaged therein.

3. The atomizer of claim 1 , wherein the substance is selected from the group consisting of natural oil, synthetic oil, high viscosity silicone, gel, wax, paraffin and combinations thereof.

4. The atomizer of claim 1 , wherein the member is ball bearings.

5. The atomizer of claim 1 , wherein the substance, member, or combination is stable at a temperature of 200° F. to 900° F.

6. The atomizer of claim 1 , wherein the substance is a high viscosity silicone stable at a temperature of 300° F. to 400° F.

7. The atomizer of claim 1 , wherein the annular channel and at least two ports are machined or formed within the atomizer disk.

8. The atomizer of claim 1 , wherein the annular channel and at least two ports are machined or formed within a component removably attached to the atomizer disk.

9. A method of fabricating a spray dryer absorber atomizer with a balancer comprising:
providing a distributor housing operable to distribute an absorbent liquid or slurry within a spray dryer absorber vessel;
providing an atomizer disk removably attached to the distributor housing comprising:
a sealed annular channel; and
at least two ports fluidly connected to the annular channel;

partially filling via a port the annular channel with a substance, member, or combination with non-Newtonian characteristics; and
sealing each of the at least two ports.

10. The method of claim 9 , wherein the annular channel and at least two ports are machined or formed within the atomizer disk.

11. The method of claim 9 , wherein the annular channel and at least two ports are machined or formed within a component removably attached to the atomizer disk.

12. A method of using a spray dryer absorber atomizer with a balancer comprising:
sealing a machined or formed annular channel of the spray dryer absorber atomizer;
filling partially the annular channel with a substance, mechanical members, or a combination thereof of non-Newtonian characteristics using at least one port of at least two ports fluidly connected to the annular channel; and
operating the spray dryer absorber atomizer for rotation thereof to disperse an absorbent liquid or slurry within a spray dryer absorber vessel.

13. The method of claim 12 , wherein the annular channel and at least two ports are machined or formed within the atomizer disk.

14. The method of claim 12 , wherein the annular channel and at least two ports are machined or formed within a component removably attached to the atomizer disk.

15. The method of claim 12 , wherein the annular channel is partially filled with a high viscosity silicone, or with a high viscosity silicone and ball bearings.
