System for ice and/or frost prevention using guided wave energy

A turbine system comprising:

• a turbine engine;
• and
• an air intake housing coupled to the turbine engine, the air intake housing including:
• an airflow tunnel including an air inlet for receiving an airflow,
• a plurality of waveguide passages positioned in the airflow tunnel,
• an air filter positioned in each waveguide passage,
• a microwave energy source coupled to each waveguide passage,
• a first screen positioned in the airflow tunnel upstream of the plurality of waveguide passages, and
• a second screen positioned in the airflow tunnel downstream of the plurality of waveguide passages,
• wherein the microwave energy sources and the first and second screens create a guided, standing wave, microwave energy that prevents at least one of ice and frost from forming on the air filters.

A system comprising:

• an airflow tunnel including an air inlet for receiving an airflow having a temperature of less than or equal to 0° C.;
• a system for preventing formation of at least one of ice and frost, the system including:
• a plurality of waveguide passages positioned in the airflow tunnel;
• an air filter positioned in each waveguide passage;
• a microwave energy source coupled to each waveguide passage, the microwave energy source generating a microwave energy having a frequency in the range of approximately 800 to 930 megaHertz;
• a first screen positioned in the airflow tunnel upstream of the plurality of waveguide passages;
• and
• a second screen positioned in the airflow tunnel downstream of the plurality of waveguide passages,
• wherein the microwave energy sources and the first and second screens create a guided, standing wave, microwave energy that prevents at least one of ice and frost from forming on the air filters.
