“…Cyclone merupakan alat pemisah antara gas dan padatan [1] yang memiliki banyak keunggulan yaitu biaya instalasi dan perawatan relatif lebih rendah dibandingkan dengan alat lainnya, dapat dioperasikan pada temperature yang tinggi, serta efisiensi pemisahannya sangat tinggi. Namun, alat ini tidak terlalu baik dalam pemisahan gas dan solid yang berukuran sangat kecil [2,3]. Salah satu cyclone yang dipasang dalam industri semen difungsikan sebagai preduster yakni alat untuk mengurangi kandungan solid dalam gas.…”

Preduster merupakan alat berbentuk cyclone yang digunakan dalam memisahkan gas dan padatan. Dalam industri semen, alat ini dipasang untuk memisahkan partikel debu dan udara panas sisa pembakaran dan pemanasan sehingga udara panas tersebut dapat dimanfaatkan kembali sebagai media pra-pemanasan bahan baku maupun media pengering batu bara. Komputasi berbasis dinamika fluida telah digunakan dalam penelitian ini karena mampu menyelesaikan persamaan perpindahan momentum, panas maupun massa. Pemodelan sistem unsteady state menggunakan algoritma Large Eddy Simulation (LES) dengan time step 0,01 selama 10 detik. Pendekatan distribusi partikel yang masuk dalam preduster menggunakan model Lagrangian. Performa preduster dinilai dari efisiensi pemisahan solidnya, pemodelan ini memprediksi efisiensi pemisahan yang terjadi selama 10 detik mencapai 70,9%.

“…This equipment is used in many industries because it has relatively low installation and maintenance costs, high separation efficiency for small particles, and be able to operate it at high temperatures. Inside the cyclone, inlet of particles and gases go through the tangential direction into the top of the cyclone [1,2]. Therefore, evaluation of preduster efficiency is needed.…”

<p>The rotary kiln in cement industries used hot air (temperature 1450<sup>0</sup>C) for doing a reaction to form a clinker. The outlet hot air from the combustion reaction in the kiln is reused to decrease the water content of coal in the coal mill. However, the hot air that contained ash will affect the drying process in the coal mills will not reach the maximum point. Therefore, the hot air needs treatment to separate the hot air and particle. The hot air is carried out to the cyclone. The goal of this study is to investigate the efficiency work of cyclones in cement industries using the CFD method. Besides, the other goal of this research will convey the expense that is reduced in decreasing the ash content in hot air. In general, the good cyclone has the low-pressure drop, the turbulence model using Reynold Average Navier Stokes (RANS) simulation,k-ε standard, with the Lagrangian model to solve the problem in particle lane. The result of this study is showing the pattern of the ash in cyclones, the pressure in cyclones, and the efficiency of cyclones. The number of efficiencies will affect the reduction of expense in this section.</p>
