<![CDATA[Penelitian ini secara eksperimental mengevaluasi pengaruh konfigurasi wet scrubber dengan 2, 3, dan 4 nozzle terhadap konsentrasi CO₂ serta profil temperatur pada bagian hilir insinerator sampah skala laboratorium. Pengujian dilakukan selama 90 menit dengan empat kali pengulangan independen untuk setiap konfigurasi. Konsentrasi CO₂ diukur pada interval 10 menit, sedangkan temperatur dipantau pada ruang bakar, tabung purifikasi, dan outlet. Dibandingkan dengan kondisi baseline, rata-rata konsentrasi CO₂ terukur mengalami penurunan masing-masing sebesar 17,29%, 25,54%, dan 44,41% pada konfigurasi 2, 3, dan 4 nozzle. Konfigurasi empat nozzle juga menghasilkan temperatur rata-rata terendah pada tabung purifikasi dan outlet. Hasil ini menunjukkan bahwa peningkatan cakupan penyemprotan (spray coverage) dapat menurunkan konsentrasi CO₂ terukur serta beban termal pada bagian hilir insinerator dalam kondisi pengujian yang dilakukan. his study experimentally evaluated the effects of 2-, 3-, and 4-nozzle wet-scrubber configurations on CO₂ concentration and downstream temperature profiles in a laboratory-scale waste incinerator. Experiments were conducted for 90 min with four independent replicates for each configuration. CO₂ concentration was measured at 10-min intervals, while temperatures were monitored in the combustion chamber, purification chamber, and outlet. Relative to the baseline condition, average measured CO₂ concentrations decreased by 17.29%, 25.54%, and 44.41% for the 2-, 3-, and 4-nozzle configurations, respectively. The four-nozzle configuration also produced the lowest average purification-chamber and outlet temperatures. These results demonstrate that increasing spray coverage can reduce the measured CO₂ concentration and thermal load downstream of the incinerator under the investigated conditions.]]>
