ABSTRACT:
The measurement is conducted by means of thermogravimetric scales (10) bearing at one end of the beam (20) a catalyst body (30) for catalysing a coking reaction of the tars present in the gas state. Precautions are taken in order to ensure homogeneity and regularity of the sampled gas flow and to guarantee predominant catalysis on the catalytic body (30), the weight increase of which gives the weight of the deposited coke and indirectly the content of tars present in the gas state in the gas to be measured. A calorimetric device (34) for analyzing gases from the coking of the tars provides a complementary and/or additional measurement. The solid tars are filtered beforehand, but their content may be measured by an auxiliary device.Possible application to analyzing gases from biomass.
