Determination of Concentration Distributions of Gaseous and Solid Intermediate Reaction Products in a Combustion Chamber by a Water Cooled Sampling Probe

Kurzfassung

The multiphase combustion process of metallised solid fuel slabs has been investigated with a water cooled sampling probe system under ramjet relevant conditions concerning the air inlet temperature. The spatial distribution of concentrations of gaseous stable (intermediate) reaction products as well as the boronoxide content of the collected solid phase inside the combustor have been determined. The sampling probe system, the sampling procedure as well as the planar step combustor test facility are described. With the continuous monitoring of the pressure inside the tip of the probe the correct operating condition of the sampling system can be observed. Concentration profiles of major species obtained at several measuring cross sections of the step combustor are presented here.
