Abstract
A method for generating a gas stream with a defined amount of nitrogen oxides includes: providing an initial gas stream; introducing a defined amount of ammonia into the initial gas stream; and generating the gas stream by converting the ammonia to nitrogen oxides. An apparatus for generating a gas stream with a defined amount of nitrogen oxides and an exhaust gas purification test facility is also provided.
Claims10

- providing an initial gas stream;
- introducing a defined amount of ammonia into the initial gas stream;
- and
- generating the gas stream by converting the ammonia into the nitrogen oxides.
1 more element
An apparatus for generating a gas stream with a defined amount of nitrogen oxides, comprising:
- a gas stream generator for generating an initial gas stream;
- a nozzle designed to introduce ammonia or urea into the initial gas stream;
- a metering unit for adjusting an introduction rate of the nozzle;
- and
- a reaction section designed to support a chemical reaction in the initial gas stream, whereby the nitrogen oxides are generated from ammonia.
