Exhaust emissions from a single shaft, nonregenerative, 90 hp gas turbine were measured at no load, two-thirds load, and full load operation on two fuels, regular kerosine and l% wt sulfur gas oil, and analyzed for sulfur dioxide, sulfur trioxide, nitrogen oxides (as NO2). unbumt hydrocarbons (hexane), aldehydes (formaldehyde), and exhaust solids. Additionally, the carbon monoxide content of the exhaust gases was continually monitored as an indication of possible changes in the engine combustion performance. This paper reports concentration levels of the various constitutents at varying engine loads for each of the two fuels.
