4.4.3 Measuring gas cleaning
Halide trap
In the operating mode with splitting the entire measuring gas from the combustion chamber
is divided in a defined ratio. Only a part of the measuring gas reaches the measuring cell for
analysis, allowing also for high chlorine concentrations to be detected. The discarded part of
the measuring gas is passed via the halide trap in the Cl module to remove the HCl from the
gas flow and protect the splitting valve and the intake pump against corrosion.
Adsorption tube
The gas extracted from the measuring cell is passed via the adsorption tube. Here the acetic
acid vapors escaping from the electrolyte is removed. Active carbon is used as adsorption
agent.
