Abstract
Abstract THIS DISCLOSURE IS CONCERNED WITH A NOVEL PROCESS FOR RAPIDLY HEATING A GAS STREAM TO A SPECIFIC RANGE OF VERY HIGH TEMPERATURES BY INTRODUCING SAID GAS STREAM TOGETHER WITH ELECTRONS OR A SOURCE THEREOF INTO A HEATING ZONE WHICH IS SUBJECTED TO THERMAL RADIATION AND WHICH CONTAINS A SUBSTANTIAL QUANTITY OF A HOT PLASMA WHICH IS PREFERABLY MAINTAINED UNDER PRESSURE. THE GAS STREAM ENTERING THE HEATING ZONE MIXES WITH THE HOT PLASMA AND ABSORBS HEAT THEREFROM AS WELL AS FROM THE WALLS OF THE HEATING ZONE ITSELF BY RADIATION. THE HEATED PLASMA IS THEN WITHDRAWN FROM THE HEATING ZONE AT A RATE SUCH THAT THE AMOUNT OF PLASMA IN THE HEATING ZONE REMAINS SUBSTANTIALLY CONSTANT.
