The knowledge of fluid–particle flow behavior is necessary. Unfortunately, computational fluid dynamics (CFD) studies are mostly focused on developing numerical methods in detail. Instead, the CFD studies should also subtly shift to become a tool for digitalizing fluid science to guide the practical industrial aspects. Therefore, this simulation study intends to reveal the air and rice husk flow behaviors in a vertical suspension furnace, complete with presenting digital simulation data, aiming to alleviate the escape particle amount. According to this study, the escaped particle amount was suppressed under more sphere particle, smaller particle size, and feed inlet pipe that sunk into the burner. The properties change from rice husk to ash, along with temperature escalation (as in combustion phenomena), enlarging the escaped particle amount, so the cyclone should be installed to handle it. In addition, the results of digital turbulent data from CFD simulation have succeeded in intriguing and revealing the fluid–particle flow behavior in the vertical suspension furnace. The data show a close match to the real phenomena occurring inside this furnace which reflects the standard k–ε model can conclusively predict fluid–particle flow behavior without conflicting Newton's second law of particle motion.

In many industries, energy auditing is important as the basis for controlling processes and designing additional equipment or modifying an existing plant. However, it requires detailed data of the materials flow, which often cannot be determined easily by direct measurement due to high-temperature limitations. This paper presents the second part of an integrated study to perform energy auditing in a separate line and in-line calciners (SLC-I) type cement plant. The second part of this study, as presented in this paper, focused on the materials flow calculation for eight separate cyclones and two calciners. The least square method was employed for solving the obtained overdetermined system equations. Using the operation data from Part 1 of the study, calculation of the detailed materials flow in each cyclone was executed. The results showed that the separation efficiency of cyclones 1A, 2A, 3A, 4A and 1B, 2B, 3B, 4B was 93.86%, 89.80%, 84.41%, 81.98% and 93.96%, 88.70%, 88.53%, 80.72% respectively and the estimated calcination percentage of kiln feed coming out of the ILC and the SLC was 85.3% and 56.3%, respectively. These values are impossible to be measured directly in the cyclones and calciners during plant operation.

“…Cyclone memiliki tiga bagian, yaitu badan berbentuk silinder vertikal (Barrel) dengan bagian bawah berbentuk kerucut (cone), inlet masuknya gas, outlet pada top cyclone untuk mengalirkan gas bersih [2]. Terdapat dua tipe cyclone dengan dimensi yang berbeda, yaitu high efficiency cyclone dan high gas rate [3]. Cyclone dengan high efficiency digunakan untuk memisahkan partikel dengan ukuran dibawah 10 mikron.…”

Cyclone is a tool for selling particulates from fluid streams without a filter. Cyclone in this case is to separate particulates from the air stream so they don't enter the coal mill. This study aims to analyze the effectiveness of the cyclone, pressure drop, and head loss in the system. The particles to be separated from the fluid stream are 9 microns in size. Pipe length for flow distribution is 67.24 m and 7 units of elbows. This analysis uses numerical methods with flow simulation features and compares them with theoretical results. Theoretical results obtained a pressure drop of 4042.74 Pa and a head loss of 607.82 m. This pressure drop is greater than the pressure fan, which is 1333 Pa. The simulation results of the inlet pipe 200 with a pressure drop of 4207.42 Pa, a head loss of 632.58 m, and an efficiency of 43%. At the inlet pipe 100 with a pressure drop of 4146.04 Pa, a head loss of 623.35 m, and an efficiency of 17%. At the inlet pipe 250 with a pressure drop of 4362.61 Pa, a head loss of 655.82 m, and an efficiency of 39%. Best results on pipe inlet 200.
