This work presents a part of a continuous research programme designed to provide information and experimental data leading to studies of soot and stable gaseous species from natural gas diffusion flame. This Test – Rig, which operates under atmospheric pressure, has along side with it a small probe (thermocouple attachment) for instantaneous measurement of temperature. The test rig has a co-annular burner consisting of a 16mm diameter steel tube (where the natural gas is injected upwardly) and surrounded by a 109mm diameter air annulus. The Rig and Facilities measures flame temperature, samples particulate matter (soot) and stable gaseous combustion product species within the flame with a well-designed Isokinetic sampling probe insert. After which, the natural gas species compositional change, soot volume fraction, soot number density can be determined with respect to axial and radial position distances from the burner rim.

Keywords: diffusion flame, temperature profile and isokinetic
