Characteristic time emissions correlations and sample optimization - GT-309 gas turbine combustor (for automobiles)

Abstract

A characteristic time model for pollutant formation (combustion inefficiency and NO/sub x/), previously quantified for axisymmetric turbulent diffusion flame combustion of a liquid fuel spray, is extended to a conventional gas turbine combustor. The model predicts the effect of changes in both combustor inlet conditions and combustor geometry on exhaust emissions and is used to demonstrate the design of a low-NO/sub x/ burner of the GT-309 class; other important design criteria such as flame stabilization are not included, however. 8 figures, 3 tables.
