Abstract
An arc heater system as a high energy heat source characterized by a housing forming a plenum chamber, a plurality of arc heaters mounted on the housing circumferentially and extending substantially radially thereon, each arc heater comprising a downstream electode adjacent to the housing and an upstream electrode remote therefrom and an intermediate gap therebetween, a polyphase wye-connected power system comprising one conductor for each phase and a neutral conductor, the upstream electrodes of each arc heater being connected to the phase conductors, the downstream electrodes being connected to the neutral conductor, whereby arc heated jet streams from the arc heaters merge and project into the housing.

An arc heater system as a high energy heat source comprising a housing forming a plenum chamber, a plurality of arc heaters mounted on the housing and extending substantially radially thereof, each arc heater comprising a downstream electrode adjacent the housing and an upstream electrode remote therefrom and an intermediate gap therebetween, a polyphase wye-connected power system comprising one conductor for each phase and a neutral conductor, the upstream electrodes of each arc heater being connected to one of the phase conductors respectively, the downstream electrodes being connected to the neutral conductor, whereby arc heated jet streams from the arc heaters merge and project into the housing.
An arc heater system as a high energy heat source comprising a housing forming a plenum chamber, a plurality of arc heaters mounted on the housing and extending substantially radially thereon, each arc heater comprising an upstream electrode and a downstream electrode and a gap therebetween, a polyphase wye-connected power system comprising one conductor for each phase and a neutral conductor, each upstream electrode being connected to one of the phase conductors, and all of the downstream electrodes being connected to the neutral conductor, whereby arc heated jet streams from the arc heaters merge and project into the housing.
An arc heater system as a high energy source comprising a metal housing forming a plenum chamber, three arc heaters mounted on the housing and extending substantially radially thereon, each arc heater comprising an upstream annular electrode, a downstream annular electrode, and an annular gap therebetween, a three-phase wye-connected power system comprising one conductor for each phase and a grounded neutral conductor, each upstream annular electrode being connected to one of the phase conductors, all of the downstream electrodes and the housing being connected to the grounded neutral conductor, and the housing having a downstream portion, whereby arc heated jet streams from the arc heaters merge and project into the housing downstream portion.
