Process and apparatus for the removal of samples for analysers from a stream of exhaust gas

摘要

In a process for the removal of samples from flue gases or other highly concentrated exhaust gases, before the sample is removed from the main stream of exhaust gas it is diluted with a carrier gas which is free from this exhaust gas. The sample is diluted in the main stream of exhaust gas by a carrier gas introduced from outside. The diluted sample can then be analyzed in conventional gas analyzers.
