Abstract
Measurements of ozone concentrations at the inlet and outlet of the ozone destructor were carried out proving the thermal decomposition of ozone produced in the ozone generator. The destructor was employed to simulate the ozone zero phenomena (OZP) in an ozone generator, thus which was separated functionally from the ozone source in the ozone generator. It was found that the thermal decomposition of ozone starts around 453 K, and the decrease of ozone concentration similar to OZP occurs at higher temperatures. In this paper, we report that the thermal decomposition of ozone is promoted by increasing the mixing ratio of oxygen atom O contained in the ozonized gas, based on a simple calculation using our measured basic coefficients.
