PROBE FOR EXTRACTING HOT SAMPLE GAS

摘要

METHOD AND APPARATUS FOR CONTINUOUSLY TAKING A HOT GAS SAMPLE TO BE ANALYZED FROM A REACTION CHAMBER In order to ensure that a sample can be taken continuously from a reaction chamber with a minimum of maintenance work, the sample gas is extracted from the reaction chamber in two identical extraction lines in alternation and at a rate which exceeds the rate required for the analysis and surplus gas which has been extracted by one extraction line is branched from the sample gas and is blown back to the reaction chamber through the other extraction line.
