Types of Powerstation's Anti-Icing system?!?

[daviwy]

Can you please let me know of different designs of anti-icing systems that can be used on different powerstations?


Please do drop more information or knowledge you have on this subject they will all be taken in and appreciated.

On gas turbines, for Anti Icing of Compressor blades, hot air is taken from the later stages of the compressor and introduced upstream of the intake filter. This air is only introduced when icing conditions are present because it affects the performance of the GT adversely

Anti-icing is also done with Propylene Glycol/water heated by exhaust heat and by air heated by exhaust heat. Some turbine firing methods don't allow the luxury of robbing compressor bleed air. If a turbine has chiller coils, the PG water is just put into the chiller coils. If not, then dedicated coils have to be added to the air filter air path.
