| Abstract: | A spray type of singlet oxygen generator for driving the Chemical Oxygen-Iodine Laser was developed. Singlet oxygen, O2(1Δg), is generated by a fast reaction of chlorine with basic hydrogen peroxide solution in the form of a dense spray. A mathematical
model of this reaction system showed that O2(1Δg) can be generated in this system with a high yield (0.70–0.80), high utilization of chlorine (0.75–0.95), and effective utilization
of liquid (0.36–0.54) at very high generator pressures (35–75 kPa). Experimental studies of this reaction system without an
efficient separation of liquid proved an efficient O2(1Δg) production characterized by a rather high product of chlorine utilization and O2(1Δg) yield (0.4–0.9) at very high generator pressures (30–80 kPa). This pressure is much higher than the operation pressure used
in other generators, which should be beneficial for a pressure recovery system of the COIL. These results provided the basis
for designing a centrifugal spray generator with an efficient separation of liquid from the gas flow, which is the subject
of the following paper. |
