Abstract

Combustion instability of a synthetic coal gas flame in a partially-premixed gas turbine combustor has been numerically studied by utilizing a lumped network code, OSCILOS. Both H2 percentage of the coal gas consisting H2 and CH4 and the length of the combustor were varied in this study. A companion experimental data were borrowed and used for validating the numerical results. The predicted results reasonably agree well with the afore-mentioned experimental ones. It was found that the mode of the instability shifted to the higher mode when H2 content of the gas became larger, and that the dominant frequency of the instability was reduced as the combustor was getting longer.
