[0111] Exhaust gas treatment experiment
[0112] by Figure 11 In the form shown, an exhaust gas treatment device was installed in a simplified model of a combined cycle power plant, and a liquid-phase reductant (ammonia) was injected at the same molar ratio as nitrogen oxides using a dispersion nozzle for exhaust gas treatment experiments. At this time, the catalyst of the catalyst module uses a zeolite-based selective catalytic reduction catalyst {a catalyst in which Fe-β zeolite (Zeolyst) is washed and coated on a honeycomb carrier}, and the catalyst of the first additional catalyst module uses V 2 o 5 The vanadium-based selective catalytic reduction catalyst is the main component, and the platinum catalyst belonging to the oxidation catalyst is used as the catalyst of the second additional catalyst module. In this case, the dispersing nozzle in the pipeline is located at a position corresponding to 3 / 8 of the above-mentioned linear distance c from the hub, and the end p...

[0118] Confirmation that the distribution of the fluid for treating pollutants at the rear end of the pipeline changes depending on the position of the dispersion nozzle in the pipeline
[0119] In order to confirm that the mixing distribution of the pollutant treatment fluid changes according to the position of the dispersion nozzle in the pipeline, the following experiment was carried out. Such as Figure 1 to Figure 4 As shown, the ammonia water is dispersed into the pipeline through the dispersing nozzle, and the concentration distribution of ammonia is measured on the expanded side of the pipeline connected to the rear end of the pipeline. At this point, air is injected at the gas turbine location to simulate the flow conditions out of the gas turbine at start-up. Dispersing nozzles on the cross-section of the pipeline such as figure 2 setup shown, along the longitudinal direction of the pipe for the above Figure 4 The straight-line distance c, increase the distance f...

[0124] It was confirmed that the distribution of the fluid for treating pollutants at the rear end of the pipe changes according to the change in the position of the tip of the dispersion nozzle.
[0125] In order to confirm that the distribution of the pollutant treatment fluid changes according to the change in the position of the tip of the dispersion nozzle, the following experiments were conducted. Specifically, in the conditions of the above experimental example 2, the position in the pipe of the dispersion nozzle is fixed at 3 / 8 of the distance c from the hub to the straight line, and the position of the end of the dispersion nozzle is changed by changing the position of the dispersion nozzle in a certain proportion with respect to the vertical line a conditions and experiment. Adjust the theoretical concentration of ammonia dispersed from the dispersing nozzle on the measuring part to 10±1ppm, and keep the rest of the experimental conditions consistent. Thus, the res...
