Oxygen in the air passing through the duct, is converted into ozone for delivery to combustion and oxygenation processes. A conducting element 12 supported on an insulated standoff 13 within a conducting duct 11 has a voltage applied between element 12 and duct 11. This voltage produces a corona on the element whereby ozone is generated. Addition of a grid 24 enhances ozone production. In addition, a provision to vary the voltage on grid 24 whereby the ozone production is controlled further enhances the device. In addition standoff 13 carries supply wire 14 whereby the electrical connection to element 12 is facilitated.
