Description:
Tracer analysis was applied to a secondary combustion chamber of a rotary kiln incinerator simulator to develop a computationally inexpensive networked ideal reactor model and allow for the later incorporation of detailed reaction mechanisms. Tracer data from sulfur dioxide tracer experiments were reconstructed using a least squares approximation that eliminated the intrinsic response of the measurement device and produced a residence time distribution between various points of the combustor. A model was chosen based on the best fit to tracer data and on consistency with physical geometry and temperature measurements. The resulting
model showed that the active path was one second shorter than the mean residence time calculated from the total volumetric flow. The analysis found that complete mixing between the kiln gas and burner stream occurs farther downstream than originally expected. Results underscore the importance of turbulence in reactor design and suggest that different design criteria are needed to ensure complete combustion.
