Abstract
This paper reports the following two topics : $\circled1$ ozone concentration (O$\sub$3con/) and discharge characteristics in flowing O$\sub$2/ with variation of Re$\sub$3/ at high voltage nozzle (HVN) of HVN 10 type ozonizer. $\circled2$ O$\sub$3con/ with variation of Re$\sub$3/ at HVN of HVN 25 type ozonizer. The important conclusions obtained from this paper are as follows. 1) In HVN 10 type ozonizer : $\circled1$ The discharge pattern can be controlled by adjustment of the Re$\sub$3/. $\circled2$ V$\sub$c/ is inversely proportional to pulse width (P$\sub$w/) and pulse frequency (P$\sub$f) $\circled3$ O$\sub$3con/ increase as decreasing of Re$\sub$3/ for constant P$\sub$w/ and P$\sub$f/. $\circled4$ O$\sub$3con/ increase as decreasing of P$\sub$w/, O$\sub$3con/ is proportional to P$\sub$f/. 2) In HVN 25 type ozonizer : O$\sub$3con/ of HVN 25 type ozonizer can increase than that of HVN 10 type ozonizer, according to parallel circuit of applied voltage and serial of supplied gas. As a result, we can obtain O$\sub$3con/ of 825[ppm] as the maximun value.
