Paper Abstract

Particle size and velocity measurements have been obtained in a low-speed (6 to 10 m/s), 2800 K combustor 30 cm in diameter. The measurements were obtained using a particle-sizing interferometer coupled to a 0.5 m spectrometer for background light rejection from radiant particles. Results obtained for the combustion of powdered coke clearly indicate the capabilities of this type of instrument to estimate combustor efficiency as a function of temperature. Comparison of the optically sampled measurements with other sampling techniques shows reasonable agreement.
