19.4.2 Dense Phase (PLIF) Modeling
Another technique used to study oxyfuel burners is
chemically sensitive–planar laser induced uorescence
(CS-PLIF).

CS-PLIF is a noninvasive, quantitative method
for visualizing ow, mixing, and chemical reactions in
complex geometries typical of commercial furnaces. The
technique provides information on burner/burner inter-
actions, burner/wall interactions, and burner interactions
with the furnace oweld/recirculation pattern.
This technique utilizes an acid solution, a base solu-
tion, a dye tracer that uoresces over a narrow range of
pH and a source of coherent radiation ( ...
