Turbine inlet air system
View Patent ↗The present application provides a turbine inlet air system. The turbine inlet air system may include a small droplet coalescer, a moisture eliminator positioned about the small droplet coalescer, and a filter downstream of the small droplet coalescer and the moisture eliminator.
1. A turbine inlet air system, comprising:
a small droplet coalescer comprising a plurality of telltales;
a moisture eliminator positioned about the small droplet coalescer; and
a filter downstream of the small droplet coalescer and the moisture eliminator.
2. The turbine inlet air system of claim 1 , wherein the plurality of telltales comprise synthetic or glass filaments.
3. The turbine inlet air system of claim 1 , wherein the plurality of telltales agglomerates small droplets to twenty (20) micron or more.
4. The turbine inlet air system of claim 1 , wherein the small droplet coalescer is positioned about an inlet of a weather hood.
5. The turbine inlet air system of claim 1 , wherein the moisture eliminator comprises a drift eliminator.
6. The turbine inlet air system of claim 1 , wherein the filter comprises a plurality of filters.
7. The turbine inlet air system of claim 1 , wherein the small droplet coalescer is positioned downstream of the moisture eliminator.
8. The turbine inlet air system of claim 1 , wherein the small droplet coalescer is positioned upstream of the moisture eliminator.
9. A method of limiting the intake of small droplets in a flow of air into a filter of a gas turbine engine, comprising:
passing the flow of air through a number of telltales of a coalescer;
agglomerating the small droplets in the flow of air into larger droplets;
eliminating the larger droplets in a moisture eliminator; and
passing the flow of air through the filter.
10. The method of claim 9 , further comprising positioning the moisture eliminator downstream of the coalescer in the weather hood.
11. The method of claim 9 , further comprising positioning the moisture eliminator upstream of the coalescer in the weather hood.
12. The method of claim 9 , wherein the step of agglomerating the small droplets into larger droplets comprises catching the small droplets in the number of telltales of the coalescer.
13. The method of claim 9 , wherein the step of agglomerating the small droplets into larger droplets comprises agglomerating the small droplets to larger droplets of twenty (20) microns or more.
14. A turbine inlet air system for limiting the intake of small droplets in an incoming flow of air, comprising:
a small droplet coalescer;
the small droplet coalescer comprising a plurality of telltales;
a moisture eliminator downstream of the small droplet coalescer;
a plurality of filters downstream of the moisture eliminator; and
a compressor downstream of the plurality of filters.
15. The turbine inlet air system of claim 14 , wherein the plurality of telltales comprise synthetic or glass filaments.
16. The turbine inlet air system of claim 14 , wherein the plurality of telltales agglomerate small droplets to twenty (20) micron or more.
17. The turbine inlet air system of claim 14 , wherein the moisture eliminator comprises a drift eliminator.
18. The turbine inlet air system of claim 1 , wherein each of the plurality of telltales comprises a flexible member having a fixed end and a free end.
19. The method of claim 9 , wherein each of the number of telltales comprises a flexible member having a fixed end and a free end.
20. The turbine inlet air system of claim 14 , wherein each of the plurality of telltales comprises a flexible member having a fixed end and a free end.
