Detailed in-furnace measurements - effects of the probe characteristics

In the context of recent studies related to the diluted combustion technologies, the combustion Unit of the Faculté Polytechnique of Mons has built several furnaces of different size. The objective was to characterize in details the diluted combustion mode and to achieve correct numerical predictions with existing combustion models ([1], [2]). In furnace measurement of temperature and species concentrations were thus realised on those furnaces with different kinds of probes. The present paper proposes a comparison of the characteristics of those probes and of their ability to be used to take gas samples in reactive mixture.
