Abstract

An ozone generation cell operating by corona discharge in an annular passage with regions of corona discharge alternating with corona-free regions where cooling takes place is improved by the incorporation of corrugated, deformable heat transfer walls in the corona-free regions. These corrugated walls impart flexibility to the structure, and thereby relieve the strain on the structural components. This permits the heat transfer wall, which is the outer of the two cylinders defining the annular passage, to center the inner of the two cylinders inside it and thus achieve a more uniform gap width in the corona regions. This is of value since the inner cylinder is preferably made of a ceramic material and not perfectly straight. The corrugations also promote turbulent flow in both the coolant medium and the gas mixture in which the ozone is generated.
