STACK MEASUREMENTS OF GAS TURBINE EXHAUST CONTAMINANTS

Measurements are reported on the important particulate and gaseous air pollutants present in the exhaust from stationary gas turbine engines (0.2-2.5 MW output range) employed as reserve power sources. Since the limited data available on gas turbine emissions have usually been obtained at the exhaust nozzle of jet aircraft engines, the measurements of this paper provide much needed data which characterize actual stationary source stack emissions. Gaseous emissions were measured employing a chemiluminescence technique for nitric oxide, nondispersive infrared analysis for carbon monoxide, and flame ionization detection for hydrocarbons. Particulate emissions were measured with liquid impingement, dry filtration, multiple-jet cascade impaction, and light extinction techniques. The measured particulate emissions are characterized by submicron particle sizes and constant emission rates with varying engine load. Correlation of the optical transmissionmeter measurements with the particulate concentration data were used to further substantiate the submicron particle size characteristic of the stack effluent. Emission levels of both the particulate and gaseous contaminants were found to be within limits established by the Los Angeles County Air Pollution Control District, which are presently the most stringent standards in force for stationary units.
