Emissions of Nitrogen Oxides from the Testing of F404-GE-400 Engines at Naval Air Station, Lemoore, California
Abstract
This report determined the weight of nitrogen oxides (NOx) coming from 13 different F404-GE-400 engine tests at NAS Lemoore. The weight of nitrogen oxides from each test was determined by adding the weights produced by each power setting used in the test. At each power setting, the amount of fuel used and the emission index for nitrogen oxides, which varies with the power setting, determine the amount of nitrogen oxides produced. The emission index is the pounds of nitrogen oxides produced per 1000 pounds of fuel used. This report used nitrogen oxides emissions data furnished by the Naval Air Propulsion Center and F404-GE-400 engine run sheets from NAS Lemoore. The weight of nitrogen oxides produced varied from 50 to 169 pounds per test. The amount of nitrogen oxides for each pound of fuel used varied form 0.01331 to 0.01742 pounds, with an average of 0.01556 pounds. This average can be used as a correlation coefficient to estimate the amount of nitrogen oxides produced during an engine test on the basis of total fuel use only. To estimate the total weight of nitrogen oxides, multiply the weight of fuel used in the test by 0.01556. Based on 13 engine test analyzed, the percentage difference between the amount of nitrogen oxides calculated from the emission indexes and correlation coefficient, varied from -11 to +17. The total amount of nitrogen oxides calculated using this coefficient agreed within 1% of the total amount calculated from the emission indexes. Axial flow fans.
