Anti-icing Systems

Specifications

Application

Air treatment system for gas turbines, industrial air compressors and diesel & gas engines in environments with risk of ice formation.

Installation options

Anti-icing by mixing the ambient air with hot air:

1. Hot air from the gas generator compressor bleed: In this case, hot air is sent through pipes from the compressor bleed into a reservoir tank, and is distributed through anti-icing nozzle in the opposite direction of the air flow. Taking hot air from the compressor affects the turbine output, usually to a maximum of 2%. This type of system can be offered with silencing to meet noise reduction requirement.

- Hot air from the GT enclosure cooling air exhaust: Ducting brings the hot air in front of the filter and it’s distributed through the ducting. A bypass damper is installed to redirect the air when the anti-icing is not required, per example in the summer.

-Anti-icing with a steam or hot water coil: Using an inlet heat exchanger upstream of the filters can also been done with a coil if there is steam or hot water available or with glycol if another source of heat is available. As this system obstructs the air flow, it has the inconvenience of adding permanent pressure drop to the system.

-Anti-icing with electric resistance: Using electric resistance heating upstream of filters – usually consisting of tightly pack aluminum fins or other conductive material. As with above, this also adds permanent pressure drop to the system.
