Noninvasive pressure sensing of drums is being investigated.
Initial results show good sensitivity even at low pressures.
This could be used to determine whether drums contain hydrogen. An experiment has been designed for controlling both the gas to the plasma torch and the surrogate waste input feed. The tests are aimed at control of the oxygen to the torch during destruction of the briquettes and then being able to change the torch gas to N2 to reduce NOx levels. The means for analyzing FTIR emission spectra on the fly have been determined. Electrode health monitor results were correlated with voltage measurements taken by the controls group to evaluate the possibility of controlling the arc attachment position within the rear electrode of the PT-150 plasma torch via variations in voltage and current.
