A Parametric Investigation of Soot Behavior and Other Emissions in a Gas Turbine Combustor.

Abstract

An investigation was conducted to determine the effects of operating characteristics and fuel additives in a gas turbine combustor on particulates (soot) and other gaseous emissions (NOx, NO). The principles of Mie theory and three-wavelength light transmittance have been utilized in this investigation to determine particulate size and mass concentration. Using an Allison T63 turboshaft engine combustor, five experimental fuels of varying chemical composition were analyzed from an emissions standpoint. There was no apparent relationship between particulate size and either fuel composition or combustor exhaust temperature. Nitric oxide levels were indifferent to fuel composition but did show a characteristics upward trend with exhaust temperature. Visible spectrum transmittance did indicate an inverse relation to increasing exhaust temperature. Though only two fuel additives were tested on one fuel, there was no manifestation of improved transmittance with their use.
