Abstract

Apparatus for oxidizing NO to NO2 in a gas stream using ozone gas comprising piping for the gas stream, tubing for the ozone gas, and pitot tubes; the piping for the gas stream including at least one hole defining an opening in the gas stream piping, an ozone carrying tube extending from outside the gas stream pipe through the opening into the interior of the gas stream pipe, an axially disposed pitot tube extending in the direction of flow of the gas stream connected to the end of the ozone carrying tube, said pitot tube adapted to aspirate ozone into the gas stream.
