Abstract

In a rural area, tamanu oil is potential to produce energy which is able to replace kerosene as fuel in a pressure stove. To replace kerosene, tamanu oil must meet the likely criterias with kerosene. One of the most important criterias is in the matter of viscosity. Tamanu oil has higher viscosity than kerosene. Heating was done to decrease the viscosity of Tamanu oil. One of many ways to determine that the viscosity criteria of tamanu oil has been nearly equal to the viscosity of kerosene is by studying spraying criteria of tamanu oil. The purpose of this research was to determine and analyze the spraying criteria of tamanu oil in a pressure stove. This research also tested modified burner designed by Lestari (2011). Spraying testing was done by giving a treatment to tamanu oil in a certain temperature. From the testing result, tamanu oil had the nearly equal characteristic with the spraying kerosene when the temperature of tamanu oil reached ± 150oC. In this temperature, diameter and spraying angle of tamanu oil was 65,67 mm and 12.40o. Whereas, diameter and spraying angle of kerosene without heating treatment was 66,75 mm and 12.60o. According to Lestari (2011), heating must be done until the temperature of tamanu oil reached ±161.81oC, so that the viscosity of tamanu oil reached 5 cP or equal with the kerosene. From the result of the modified burner testing, apparently burner in a pressure stove could heat tamanu oil to reach 164.7oC temperature. Thus, we could conclude that modified burner in a pressure stove can decrease the viscosity of tamanu oil to reach a nearly equal with kerosene.
