Setup for plasma ignition


The setup based on microwave method of plasma ignition allows one to ignite the plasma combustion processing directly at the needed point. This can be done due to a high density of microwave energy in small area at the end of single-conductor line. The setup allows one to turn the required energetic regime using microwave power control scheme. Application of single-conductor line provides effective and easy way to conduct the microwave power without losses to the required region.

Innovative Aspect and Main Advantages

This technology is very attractive in plasma combustion systems application due to its low cost, simple design and since its easy in service such as conventional microwave oven. The setup based on this technology can be operated in a wide frequency range from several GHz to THz and in a wide output power range from several W to hundreds kW with efficiency not less then 50 percents. Due to this flexibility of output power mode the proposed technology can be applied in wide class of plasma systems from the systems with small volume of plasma to rather big plasma systems. Another advantage of the proposed setup is its compact dimensions, which is limited by only microwave oscillator size. The presented setup consists of oscillator with power supply unit based on conventional microwave oven unit (400mm*400mm*200mm), waveguide resonator with length 250mm and single-conductor line (line length can be from several cm to several meters).

Areas of Application

The setup based on this technology can be utilized as plasma ignition system in plasma combustion technologies:
1) Plasma Assisted Combustion
2) Metal Heat Treatment Industry
3) Systems for Treatment of Soil and other Materials

Plasma Aerodynamics.

1)oscillator, 2)waveguide resonator, 3)plunger, 4)coaxial line, 5)inner conductor,
6)single – conductor line.

Stage of Development

The technology is tested, available for demonstration – field tested. In particular, the setup operating in 2,45 GHz range for energy range up to 0,5 kW is tested in wide pressure range as plasma igniter system.
