| 摘要 |
The present invention provides: A glow discharge heating apparatus comprising at least one pair of discharge electrodes disposed in opposite relationship to form a predetermined gap therebetween, means for applying a voltage across said discharge electrodes to cause a glow discharge therebetween, said glow discharge supplying thermal energy to the discharge electrode acting as a cathode during said glow discharge, and a liquid to be heated flowing through said discharge electrode acting as said cathode to be heated with said thermal energy wherein an area with which said discharge electrodes are opposite to each other is smaller than an area of a portion of one of said discharge electrodes having caused thereon said glow discharge thereby to impart positive resistance characteristic to the current-to-voltage characteristic of said glow discharge. |
