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.
