Harianto, Bagus (2014) Pengaruh Ketebalan Circular Tube Burner Terhadap Karakteristik Pembakaran Premixed Uap Minyak Jarak. Sarjana thesis, Universitas Brawijaya.

Abstract

Kebutuhan energi dalam kehidupan manusia tiap tahun meningkat seiring dengan kemajuan teknologi dan perkembangan zaman, baik untuk kepentingan rumah tangga atau industri. Ketergantungan yang berlebihan terhadap sumber energi tak terbaharukan akan menimbulkan beberapa masalah sehingga saat ini banyak dikembangkan bahan bakar dari minyak nabati yang salah satunya adalah minyak jarak. Di dalam proses pembakaran, kestabilan api memegang peranan yang sangat penting. Api dikatakan stabil apabila stasioner pada posisi tertentu, hal ini terjadi bila kecepatan gas reaktan sama dengan kecepatan perambatan api. Banyak faktor yang mempengaruhi kestabilan api dan kecepatan pembakaran salah satunya adalah geometri burner. Penelitian ini dilakukan untuk mengetahui pengaruh ketebalan circular tube burner terhadap karakteristik pembakaran premixed minyak jarak. Karakteristik pembakaran yang diteliti berupa kestabilan api, kecepatan pembakaran, dimensi api dan temperatur api. Penelitian ini dilakukan dengan memanaskan minyak jarak pada ketel agar menjadi uap bahan bakar. Uap tersebut disalurkan ke burner yang nantinya akan bercampur dengan debit udara yang divariasikan. Burner yang digunakan dalam penelitian ini berbahan kuningan yang memiliki ketebalan 0,5; 1; dan 2 mm dengan diameter dalam 3 mm. Dari hasil penelitian didapati bahwa dengan bertambah tebalnya circular tube burner pada equivalence ratio yang sama menyebabkan kecenderungan tinggi api semakin berkurang, kecepatan pembakaran semakin bertambah dan temperatur api juga semakin besar. Selain itu, ketebalan circular tube burner juga mempengaruhi nyala api pembakaran premixed minyak jarak dan mempengaruhi stabilitas api. Semakin tebal burner maka api akan cenderung lebih stabil (tidak mudah blow off).
