The ozone generator must be capable of generating sufficient and stable
levels of ozone for reaction with NO to generate NO
2
concentrations in the
range required.
Note
Ozone generators of the electric discharge type may produce NO and
NO
2
and are not recommended.
▲
A valve can be used to divert the NO flow when zero air is required at the
manifold.
The reaction chamber used for the reaction of ozone with excess NO
should have sufficient volume so that the residence time meets the
requirements specified in this chapter.
The mixing chamber is used to provide thorough mixing of the reaction
products and diluent air.
