7.6 Injection nozzle installation
Injection nozzles are used to mix the metered process fluid into a main stream and simultaneously fulfill a
non-return function. The injection nozzle is usually installed in the main line from above. Installation from
below is only recommended in the case of media with a tendency to crystallize. Thus entrapped air is able
to leave.
In the case of media with a tendency to contaminate the injection nozzle, it is advisable to use an injection
nozzle which can be dismantled for maintenance and shut off.
