Show Measurement Ilnd Interpretlltion - 20 - of Fillmes Issued from a Generic Multi-Fuel Burner IFRF-~ unaffected for the combustion air staging. In-furnace natural gas rebum.ing produced even more dramatic success in lowering NOx emissions although the particulate emissions may be adversely effected. Spray characterization has been completed with the PDA technique for a number of detailed cases and parametric studies. These data have been analyzed and implemented with the complementary boundary conditions into computations with a commercial CFD code. The preliminary predictions show good agreement with the data obtained in the flame characterizations conducted during the burner tests. With further refinements the algorithms developed as a consequence of this modeling effort will be a useful predictive tool for interpreting/predicting the performance of oil burners. 7.
