Sarin, Pipit Runnita Melinda (2018) Simulasi Pengaruh Variasi Diameter Bunsen Burner terhadap Karakteristik Nyala Api Premix Gas Metana. Sarjana thesis, Universitas Brawijaya.
Abstract
Gas alam sangat cocok digunakan sebagai bahan bakar alternatif yang ramah lingkungan pengganti minyak tanah, LPG, batu bara maupun bahan-bahan lain yang berasal dari fosil. Perlunya bahan bakar alternatif karena semakin banyaknya alat-alat teknologi yang beralih ke gas alam. Wardana (2008) mengungkapkan dalam gas alam, terkandung kurang lebih 96% gas metana (CH4). Berdasarkan penelitian tersebut sangat perlu mendapatkan ilmu dan pengetahuan tentang karakteristik dan sifat pembakaran yang baik untuk metana. Penelitian ini menggunakan metode simuasi numerik , banyak kelebihan yang dapat disajikan dalam menyelesaikan masalah terutama dalam dunia engineering. Pada proses pembakaran kecepatan api dapat berpengaruh pada mekanisme nyala api gas metana, untuk dapat mengetahui reaksi pembakaran dapat menggunakan piranti bunsen burner. Pada penelitian ini dilakukan lima variasi ukuran diameter bunsen burner yaitu 8 mm, 9 mm, 10 mm, 11 mm dan 12 mm untuk mengetahui pengaruhnya terhadap karakteristik nyala api dengan diuji menggunakan variasi ekuivalen rasio 1,05; 1,12; 1,23; 1,36; 1,49 dan 1,68. Hasil dari penelitian ini adalah variasi diameter bunsen burner memiliki pengaruh terhadap karakteristik nyala api. Kecepatan api laminer akan semakin kecil sering bertambahnya ukuran diameter, tinggi api dan temperatur api akan semakin rendah seiring semakin besar ukuran diameter bunsen burner. Berdasarkan pengujian dengan nilai ekuivalen rasio maka tinggi api akan semakin naik, kecepatan dan temperatur api akan turun seiring dengan kenaikan nilai ekuivalen rasio. Dari data yang dihasilkan dari proses simulasi menunjukkan trendline yang hampir sama dengan hasil pengujian secara eksperimental hanya nilainya lebih tinggi hal ini disebabkan hasil simulasi tidak terpengaruh faktor lain seperti heatloss ataupun lainnya.
English Abstract
Natural gas is suitable for use as an environmentally friendly alternative to kerosene, LPG, coal and other fossil materials. The alternative fuels is due to the increasing number of technological tools that are turning to natural gas. Wardana (2008) revealed in natural gas, contained approximately 96% methane gas (CH4). Based on these studies it is necessary to gain knowledge and knowledge about the characteristics and properties of good combustion for methane. This research uses numerical simulation method, many advantages that can be presented in solving problems especially in the world of engineering. One of them is the field of energy conversion that is the combustion process. In the combustion process the flame velocity can affect the flame mechanism of methane gas, to be able to know the combustion reaction can use bunsen burner tool. This research, used five variations of bunsen burner diameter were 8 mm, 9 mm, 10 mm, 11 mm and 12 mm to determine the effect on flame characteristics tested by variation of equivalent ratio of 0.67; 0.74; 1.0; 1.35; 1.49; and 1.69. The result of this research is variation of bunsen burner diameter have influence to flame characteristic. The laminer flame speed will be smaller as the diameter increases, the flame height and flame temperature will be decreased when the bunsen burner diameter was increasing. Based on the examine with increasing the ratio equivalent, the flame’s height will increase, then the laminer flame speed and temperature will decrease. From the data generated from the simulation process shows a trendline that is almost the same as the experimental test results only higher value this is because the simulation results are not affected by other factors such as heatloss or other.
