Komponen penting pada FBB adalah nosel udara (air-cap) yang menentukan distribusi udara, konsumsi energi, dan efisiensi operasi. Penelitian ini mengkaji kinerja air-cap tipe lonceng melalui pendekatan teoretis dan uji dingin (cold test) menggunakan material bed pasir silika. Hasil pengamatan menunjukkan erosi dan retakan air-cap terutama dipicu oleh gesekan fluida pembawa partikel pengotor serta tumbukan partikel besar yang mempercepat penipisan permukaan. Kecepatan minimum fluidisasi (Umf) pada tinggi unggun 20 cm tercapai pada 130 cm/s, sedangkan pada 30 cm meningkat menjadi 145 cm/s, dan pada 40 cm belum tercapai hingga 160 cm/s sehingga masih berada pada kondisi fixed bed. Perbandingan desain menunjukkan air-cap inovatif mampu menurunkan pressure drop hingga ~35% dan konsumsi daya blower hingga 41%. Temuan ini menegaskan bahwa desain inovatif lebih efisien dalam distribusi udara dan berpotensi memberikan penghematan energi signifikan dibandingkan air-cap konvensional. date: 2026-04-07 date_type: published pages: 56 institution: Fakultas Teknik Universitas Sultan Ageng Tirtayasa department: Teknik Kimia thesis_type: sarjana thesis_name: sarjana official_url: https://tinyurl.com/y2papdxc related_url_url: https://tinyurl.com/y2papdxc related_url_type: author referencetext: Kale, A., Kamdi, N.
