Abstract
Charging system berperan sebagai pengatur distribusi burden materials di dalam Mini Blast Furnace. Selanjutnya, distribusi burden materials akan mempengaruhi aliran gas di dalam reaktor. Sehingga charging system memegang peranan penting terhadap proses pengolahan. Oleh karena itu, penelitian ini difokuskan untuk menganalisis pengaruh ukuran diameter large bell pada charging system dengan tipe double-bell system terhadap distribusi burden materials di dalam Mini Blast Furnace menggunakan Solid Particle Model. Setelah dianalisis, perbedaan diameter large bell menghasilkan distribusi burden materials yang berbeda. Semakin besar diameter large bell, titik impak yang kemudian akan menjadi puncak layer akan semakin mendekati wall dan sebaliknya. Sedangkan untuk penyebab deformasi layer terbesar adalah gravity failure akibat kondisi layer yang tidak stabil. Untuk distribusi partikel, partikel dengan massa dan ukuran lebih kecil (dolomite) cenderung terkonsentrasi pada daerah centre dan sebaliknya. Apabila ditinjau dari aliran gas untuk proses start-up, variabel dengan perbandingan diameter large bell dan diameter dalam Mini Blast Furnace 7:10 merupakan yang terbaik.
=================================================================
Charging system controls burden material distribution in Mini Blast Furnace. Furthermore, burden materials distribution influences gas flow in the reactor. So, charging system has an important role for Mini Blast Furnace process. Therefore, this research focuses to analyse the influences of large bell diameter size in charging system that used double-bell system for burden materials distribution in Mini Blast Furnace using Solid Particle Model. After analysed, the differences of large bell diameter size produce different burden materials distribution. The greater diameter size of large bell, impact point that will be the peak of layer will draw near to the wall and vice versa. The majority layer deformation is caused by gravity failure due to the stability of layer. For particle distribution, the heavier and smaller particle (dolomite) tends to centre area and vice versa. For the start-up proscess, variabel that has a ratio large bell diameter and Mini Blast Furnace inner diameter 7:10 has the best gas flow in the reactor.
