Abstract

Pemanfaat Gas hasil gasifikasi biomassa serbuk kayu dapat digunakan untuk berbagai kebutuhan sehari-hari. Salah satu pemanfaatanya sebagai bahan bakar burner gas. Dibutuhkan burner gas yang sesuai untuk memanfaatkan gas hasil gasifikasi yang biasa disebut syngas. Penelitian ini bertujuan untuk mendapatkan dimensi mixed chamber yang tepat dan kondisi operasi yang optimal untuk burner syngas type partially premixed. Selain itu juga untuk mendapatkan karakteristik unjuk kerja burner gas type partially premixed. Penelitian dilakukan di Laboratorium Teknik Pembakaran dan Bahan Bakar, jurusan teknik mesin ITS. Bahan bakar yang digunakan adalah syngas hasil gasifikasi biomassa serbuk kayu. Metode yang dilakukan adalah eksperimental dengan variasi perubahan dimensi mixed chamber dengan merubah jarak pipa bahan bakar (Nozzle) terhadap combustion chamber dengan variasi 0 cm hingga 4 cm dengan kenaikan 1 cm dan variasi tekanan bahan bakar syngas mulai dari 0,2 bar sampai 1,2 bar dengan kenaikan 0,2 bar. Parameter yang diukur adalah tekanan, distribusi temperatur api, ΔL Inclined manometer (θ = 15˚) dan Visualisasi nyala api. Sedangkan parameter unjuk kerja yang dihitung adalah laju aliran massa udara dan bahan bakar, daya Burner, konsumsi bahan bakar spesific dan effisiensi. ii Dari penelitian ini didapatkan hasil burner yang memiliki distribusi temperatur api maksimum sebesar 448,15 oC pada tekanan syngas 1,2 bar dengan posisi nozle 1 cm dari ujung mixed chamber. Serta diperoleh daya burner tertinggi sebesar 30,30 kW dan efisiensi tertinggi sebesar 47,17 % pada tekanan syngas 1,2 bar dengan posisi nozle 1 cm, dan konsumsi bahan bakar spesifik optimum 0,82 kg/ kW h. Dari data hasil penelitian yang didapatkan dapat disimpulkan dengan hasil unjuk kerja yang didapat dimensi mixed chamber yang terbaik saat nozzle pada posisi 1 cm pada kondisi tekanan 1,2 bar. =============================================================================================== Gas utilizations of wood powder biomass gasification can be used for any daily needs. One of them can be used as fuel of gas burned and it takes some equality to utilize the gas of gasification named syngas. This research is aimed to determine an actual mixed chamber dimenssion and an optimal partially premixed syngas oparation. Futhermore, It aimed to obtain characteristic of partially premixed gas burner performance. The Research is conducted at Combustion and Fuels Laboratory of Mechanical Engineering Department of ITS. The used fuel is syngas which made of wood powder biomass gasification with experimental method. Actually, this research is changed its dimession of mixed chamber by changing its fuel pipe distnace (nozzle) according to combustion chamber with 0 cm to 4 cm in length after 1 cm in every increasing and 0,2 bar in every increasing of fuel pressure, started from 0,2 bar to 1,2 bar. The measured parematers are pressure, distribution of flame temerature, ΔL Inclined manometer (θ = 15˚), and flame visualization meanwhile the determined parameters are mass flowrate of air and fuels, combustion power,specific fuels consumption and efficiency. iv The results of this research are the highest distribution of flame temperature is 448,15 oC settled on 1,2 bar of syngas pressure with 1 cm of nozzle from the butt off and 0,82 kg/ kW h of optimally specific fuels consumption. Then it can be concluded that the best performance of this research is occured at 1 cm of nozzle position with 1,2 bar of its pressure.
