Characteristic time emissions correlations - The T-63 helicopter gas turbine combustor

Abstract

Gaseous pollutant emissions from conventional diffusion flame T-63 combustors are correlated as functions of combustor geometry and inlet conditions in terms of a characteristic time model. New aspects of the present study show partial inclusion of effects of alternate fuel properties, suggest a generalization of the Lipfert NO/sub x/ correlation, compare advanced film injected and prevaporizing/premixing with conventional combustors, and demonstrate a quantitative relation between emissions of unburned hydrocarbons and CO. 9 figures, 4 tables.
