Destrucción de VOCs con plasma de Helio 44 1.4.4. Effect of the cross section of the tip of the plasma torch on the destruction efficiency There are circumstances under which poor energy efficiencies were obtained as can be seen from the previous figures. With the present set-up it is possible to improve the energy efficiency by changing the tip of the torch where the plasma is ejected. This is not surprising, as the destruction efficiency depends on the plasma volume and the residence time and these parameters depend directly on the velocity of the gas as it exits the tip. Thus, if we use a higher cross-section in the tip, we can achieve destruction of a larger quantity of TCE with the same destruction percentage, because a higher flow is necessary to maintain the same velocity of gas in the tip, if we maintain a fixed concentration of TCE in the gas. Fig. 1.7 compares the results of experiments using 1000 ppm of TCE with four different internal diameters of the tip. The dash-dot lines link points with the same velocity of gas in the tip, and we observe that these points have the same destruction and removal efficiency. This demonstrates that the %DRE depends strongly on the velocity of the gas at the exit of the tip. % DRE 99,9994 99,9992 99,9990 99,9988 99,9986 99,9984 99,9982 99,9980 MW Power: 300 W Concentration: 1000 ppm Tip D 1 = 1,2 mm Tip D 2 = 1,0 mm Tip D 3 = 0,8 mm Tip D 4 = 0,6 mm 0,0 0,5 1,0 1,5 2,0 2,5 3,0 Total Flow (L/min) Figure 1.7: Comparison of the destruction capabilities of four different tips of the torch.
