Abstract

Nilai efisiensi boiler Circulating Fluidized Bed (CFB) pada perusahaan gula rafinasi mengalami penurunan akibat ketidaksesuaian karakteristik batubara aktual dengan spesifikasi desain awal, sehingga proses pembakaran menjadi kurang optimal. Penelitian ini bertujuan mendesain ruang bakar boiler CFB berdasarkan karakteristik batubara aktual. Metode penelitian meliputi analisis stoikiometri pembakaran, neraca massa dan energi, perancangan dimensi ruang bakar, serta analisis hasil perancangan. Hasil menunjukkan penyesuaian dimensi ruang bakar menghasilkan kecepatan fluidisasi 4,04 m/s, temperatur ruang bakar 877,42 °C, dan temperatur gas buang 146,96 °C. Hasil perancangan menunjukkan potensi peningkatkan efisiensi boiler dari 70,76% menjadi 83,31%, dan menurunkan konsumsi batubara dari 3,31 menjadi 2,78 kg/s.
