Abstract

Penelitian ini dilakukan dengan tujuan merancang sebuah dryer bahan bakar yang dapat digunakan untuk mengeringkan bahan bakar kelapa sawit sebelum digunakan sebagai bahan bakar boiler. Penelitian dilakukan dengan menggunakan simulasi dari CFD. Sebelum dilakukan perancangan dryer terlebih dahulu ditentukan lokasi pengambilan panas buang. Setelah itu dilakukan perhitungan potensi panas buang yang dapat digunakan untuk mengeringkan bahan bakar. Potensi panas buang yang didapatkan kemudian digunakan kembali untuk menentukan lamanya waktu pengeringan untuk bahan bakar kelapa sawit yang digunakan. Kemudian dilakukan perancangan desain dryer bahan bakar yang digunakan serta menentukan lokasi input, output serta mekanisme pergerakan dryer. Desain dryer kemudian disimulasikan untuk melihat karakteristik dryer seperti sebaran kecepatan udara serta sebaran temperatur didalam dryer. Hasil yang didapat berdasarkan simulasi yaitu persebaran kecepatan udara didalam dryer memiliki rentang nilai 0-36 m/s dengan kecepatan tertinggi timbul disaat udara panas buang memasuki dryer sedangkan persebaran temperatur didalam dryer memiliki rentang nilai 90-270oC dengan suhu tertinggi muncul disekitar saluran masuk udara panas buang dan suhu terendah muncul dibagian keluaran udara panas dari dryer. ================================================================= This study was conducted with the aim to design a fuel dryer that can be used to dry palm oil bahan bakar before being used as boiler fuel. The study was conducted using simulation of CFD. Prior to the design of the dryer the location of waste heat must be determined. After that the potential of waste heat must be calculated. The waste heat potential obtained then reused to determine the duration of drying time of bahan bakar used. Then the design of bahan bakar dryer is used to determine the location of input, output and dryer movement mechanism. The dryer design then simulated to see dryer characteristics such as air velocity distribution and temperature distribution in the dryer. The results obtained based on the simulation of the air velocity diffusion in the dryer has a range of values 0-36 m/s with the highest speed occurs when the hot air exhaust enter the dryer while the temperature spread in the dryer has a range of values between 90 and 270oC with the highest temperature appears around the inlet and the lowest temperature appears at the heat output from the dryer.
