Abstract
An ozone generating apparatus includes an ozone generator having concentric electrodes and a means for generating a corona discharge between the electrodes, a pump for recirculating a portion of the ozone-containing gas leaving the generator through a conduit which is configured to receive a portion of the ozone containing gas, and a heat exchanger for cooling the recirculated portion of the ozone-containing gas. An oxygen-containing gas is also introduced to the heat exchanger and combined with the recirculated gas portion to form a feed gas which is chilled in the heat exchanger and then introduced into the generator.

An apparatus for generating ozone, comprising:
- (a) an ozone generator having a first electrode and a second electrode spaced from each other and defining between them an ozone generation zone, the zone having an inlet for receiving a feed gas comprising oxygen and an outlet for releasing a gas mixture comprising the feed gas and ozone generated in the zone, one surface of the first electrode being in heat exchange relation with a first coolant;
- (b) means for generating a corona discharge in the zone;
- (c) a heat exchanger having a gas side in heat exchange relation with a first coolant side and in fluid communication with the zone, the first coolant side containing a second coolant;
- (d) a conduit in fluid communication between the zone and the gas side of the heat exchanger, and being configured for receiving a portion of the gas mixture;
- and
- (e) a pump for circulating the portion of the gas mixture through the conduit, the heat exchanger and the zone.
A method for generating a gas comprising ozone, comprising the steps of:
- (a) introducing a feed gas comprising oxygen into an ozone generation zone between a first electrode and a second electrode in an ozone generator;
- (b) creating a corona discharge between the first electrode and the second electrode to generate ozone within the zone;
- (c) cooling a surface of the first electrode with a first coolant;
- (d) releasing a mixture of the ozone and the feed gas from the zone;
- (e) drawing a first portion of the mixture released from the zone through a heat exchanger to cool the mixture;
- and
- (f) combining the first portion of the mixture with a gas comprising oxygen to form the feed gas.
