THE NOL 3 MW 3-PHASE A-C ARC HEATER (MARK II).
Abstract
An a-c arc heater developed for the NOL 3 MW research arc is described. This heater has three doughnut-shaped electrodes with internal coils to increase the magnetic field strength. The operation and performance of this design are discussed. Temperatures from 3500 to 4000 K with efficiencies from 15 to 23% were obtained at pressures from 10 to 15 atmospheres. Multiple arc streamers and the diffusion of the arc into the center of the chamber were observed. A high level of contamination of the effluent gas, an unsatisfactory magnetic design, and short component life make the design unsatisfactory. Methods of eliminating these problems are discussed.
