Measurement of Pollutant Emissions from an Afterburning Turbojet Engine at Ground Level. II. Gaseous Emissions
Abstract
The performance of a sampling and measurement system for the gaseous species of carbon monoxide (CO), carbon dioxide (CO2), total hydrocarbons (C(x) H(y)), nitrogen dioxide (NO2), and total oxides of nitrogen (NO(x)) was demonstrated for an afterburning turbojet engine power conditions from idle to maximum afterburning at ground level. Data were obtained, using a protable emissions measurement system, at positions ranging from immediately at the nozzle exit to 96 ft aft of the nozzle exit plane. A J85-GE-5 engine was used to generate the gaseous emissions. Nondispersive infrared detectors were used for CO and CO2 measurements; a flame ionization detector was used for C(x)H(y) measurements; and electrochemical devices operating on the fuel cell principle were used for NO2 and NO(x) measurements. The effects of inlet humidity and crosswind velocity on the quantity and distribution of gaseous species in the exhaust plume were determined.
