率の向上が顕著であることがわかる。Furthermore, in the same way as in (b) above, FIG. 2 shows that with the metal object to be heated (1) grounded, a positive voltage is applied to the metal burner (5) from a DC power supply to create a potential difference ( This is a graph showing the degree of increase (% difference) in heat transfer efficiency when an electric field is applied compared to when no electric field is applied, using the additional voltage (g) to the burner (5) as a buff meter, and as a result it shows,
It can be seen that the heat transfer efficiency is significantly improved when the applied voltage M to the burner (5) is equal to or higher than jKV.
