Fuel Tolerance of Staged Combustors

The work described herein was conducted under an Electric Power Research Institute contract, Evaluation of Synthetic Fuel Character Effects on Rich-Lean Stationary Gas Turbine Combustion Systems. The purpose of this program was to determine the effect of synthetic fuel properties on combustor emissions, performance, and durability. Four synthetic fuels and No. 2 petroleum distillate fuel were tested in a subscale combustor over a wide range of conditions with the purpose of expanding the fuels property base and range of conditions beyond that of preceding programs. Nox emissions were very low and insensitive to combustor pressure and fuel-bound nitrogen. Rich-lean results show some indication of increased smoke and liner heating with reduced fuel hydrogen content, although not as consistent as the trends for lean combustors.Copyright © 1982 by ASME
