Abstract

A hazardou waste incinerator which utilizes a cyclotron resonance plasma. The plasma is generated by introducing vaporized hazardous material and a feed gas into a vacuum chamber. The chamber has a magnetic field source and an electromagnetic radiation source. The cyclotron resonance plasma is produced by the resonance that occurs when the frequency of the electromagnetic radiation is set equal to that of the gyration of electrons or other charged particles in the magnetic field according to the formula: F.sub.res =(1/2.pi.)(qB/m) hertz Where q is the charge of the electron or ion, B is the strength of the magnetic field and m is the mass of the electron or ion. The strength of the electromagnetic radiation is adjusted so that the flowing gases are ionized, forming a plasma. During the reaction, the charged particles collide with neutral particles, providing both ionization and fragmentation (the breaking up of high-mass molecules into lower mass fragments). When electromagnetic radiation is applied at the ion cyclotron resonance frequency for a particular charge-to-mass ratio, ions of this ratio are accelerated outward and colilde with other particles in the plasma. This can resul…
