Abstract

Distribusi temperatur nyala api blow-torch dapat ditampilkan secara isothermal bidang sehingga akan terlihat pola bidang – bidang temperatur. Bahan bakar utama yg diujikan adalah kerosin dengan bahan bakar extender gas HHO yang diperoleh dengan cara elektrolisa air yang kemudian di premix sebelum dibakar. Penelitian ini dilakukan secara true experimental laboratory pada Lab TPBB Jurusan Teknik Mesin FTI ITS untuk diketahui pola bidang – bidang temperatur yang menggunakan bahan bakar kerosin + gas HHO dibanding dengan blow-torch yang hanya berbahan bakar kerosin saja. Variasi yg digunakan dalam penelitian ini adalah jumlah kerosin yang masuk di mixing chamber mulai dari kerosin murni, kerosin bukaan katup 25% + gas HHO, dan kerosin bukaan katup 50% + gas HHO. Gas HHO yang masuk ke ruang bakar didapat dari generator buatan peneliti dengan laju produksi 2,3 LPM. Parameter nyala api yang diukur adalah panjang api, temperatur api, iso temperatur (bidang), daya bahan bakar dan radiasi api blow-torch. Hasil penelitian dan analisa data didapatkan temperatur tertinggi ujung api dihasilkan oleh variasi kerosin bukaan katup 50% + gas HHO yaitu sebesar 800 oC, sedangkan kerosin murni temperaturnya hanya 550 oC. Terjadi peningkatan daya bahan bakar pada blow-torch. Pada kerosin murni, daya yang dihasilkan sebesar 38.087 watt, kerosin bukaan katup 25% + gas HHO meningkat menjadi sebesar 39.445 watt, sedangkan pada kerosin bukaan katup 50% + gas HHO meningkat menjadi sebesar 39.969 watt. Dari ketiga variasi, radiasi api dan distribusi temperatur rata-rata api tertinggi dihasilkan oleh variasi kerosin bukaan katup 50% + gas HHO, titik puncak api juga menjadi lebih maju. Dapat disimpulkan bahwa blow-torch dengan bahan bakar mixing kerosin + gas HHO bisa digunakan untuk memanaskan furnace yang membutuhkan panas tinggi secara radiasi. ========== The temperature distribution of blow-torch flame can be displayed in isothermal field so it will look pattern fields of temperature. The main fuel is kerosene which tested the fuel extender HHO gas obtained by electrolysis of water which was then in the premix before burning. This study was carried out with true experimental laboratory in Department of Mechanical Engineering Laboratory TPBB FTI ITS for known patterns of the fields that uses the fuel temperature kerosene + HHO gas compared with blow-torch that only fueled kerosene. Variations that are used in this study is the number of incoming kerosene in mixing chamber ranging from pure kerosene, kerosene valve opening 25% + HHO gas, and kerosene valve opening 50% + HHO gas. The HHO gas into the fuel obtained from artificial generator researcher at the rate of 2.3 LPM. Parameters measured flame is long fire, flame temperature, isothermal field, power and radiation blow-torch flame. Results of research and data analysis obtained the highest temperature flame tip produced by variations in the valve opening kerosene 50% + HHO gas is equal to 800°C, while the temperature of pure kerosene just 550°C. An increase in the power of fuel in blow-torch. On pure kerosene, the power generated by 38087 watts, kerosene valve opening 25% + HHO gas increased to 39445 watts, while the valve opening kerosene 50% + HHO gas increased to 39969 watts. Of the three variations, flame radiation and temperature distribution on average the highest flame produced by variations in the valve opening kerosene 50% + HHO gas, the cusp of the fire also become more advanced. It can be concluded that the blow-torch with fuel mixing kerosene + HHO gas can be used to heat the furnaces that require high heat radiation.
