"System For Ice And/Or Frost Prevention Using Guided Wave Energy"

Abstract: An ice and/or frost preventing system for positioning in an airflow tunnel (120) having an air inlet (122) includes a plurality of waveguide passages (142) positioned in the airflow tunnel (120); an air filter (130) positioned in each waveguide passage (142); a microwave energy source (150) coupled to each waveguide passage (142); a first screen (160) positioned in the airflow tunnel (120) upstream of the plurality of waveguide passages (142); and a second screen (162) positioned in the airflow tunnel (120) downstream of the plurality of waveguide passages (142). The microwave energy sources (150) and the first and second screens (162) create a guided, standing wave, microwave energy (170) that substantially prevents at least one of ice and frost from forming on the air filters (130). A turbine system (90) including the ice and/or frost preventing system is also described.
