Abstract
Ozone is generated from an oxygen-containing gas utilizing a tube-type ozone generator at significantly greater power efficiency. The oxygen is introduced into the annular passageway between the electrodes of the tube-type ozone generator at an angle (e.g. about 45.degree.-90.degree.) so that it swirls in a cyclonic flow path as it travels from one end of the annular passageway to the other. The amount of power consumed to produce a gas having about 8% ozone is roughly half of the power needed if the same conditions are applied but the oxygen gas is introduced conventionally (without swirling action, so that it travels along the dimension of elongation of the passageway). The swirling action also allows a higher concentration of ozone (e.g. 10% or more) to be achieved in the product gas compared to the same conditions when no swirling is employed. Cooling fluid, such as nitrogen gas, may be passed through an interior passageway and outside the outer electrode either co-current or countercurrent to the general direction of oxygen gas flow.
