Abstract

An ozone generator meant for continuously supplying highly concentrated (HC) ozone gas for low-temprature oxidation process was presented. The generator comprised of four ozone vessels and could supply a constant flow of HC ozone by four modes of operations, such as accumulation, vaporization, evacuation and cooling to each of the ozone vessels. The maximum flow rate for a continuous supply of ozone gas was 60 sccm with a flux stability of ± 1.1%. It was shown that ozone concentration of over 99.5 % could be achieved by the ozone generators.
