Emissions from and within an Allison J-33 Combustor II:The Effect of Inlet Air Temperature

摘要

A model of the flow pattern within an Allison J-33 combustor using unheated inlet air was previously postulated (Mellor et al. 1972b), based on internal measurements. Additional data consistent with the postulated flow model were obtained from the same combustor using heated inlet air at near design conditions. Profiles of gas temperature, carbon monoxide, unburned hydrocarbons, and nitric oxide concentrations are reported as a function of axial and radial position inside the combustor. Combustor exit plane pollutant concentrations are also reported; specifically, the effects of combustor pressure, overall equivalence ratio, air flow rate, and inlet air temperature were investigated.
