Analysis of castel type biomass combustion chamber using candlenut shell fuel for patchouli oil purifying

Abstract

The combustion chamber is one of the tools used to cultivate plantation, with fuel predetermined. Most people in rural areas the largest users of fossil fuels derived from kerosene, gasoline, petrol, LPG gas, coal and firewood. One agricultural wastes that can be utilized the candlenut shells capable of generating heat energy can help problems of crisis fossil fuel. Biomass fuel type castel space is one of main tools that can convert biomass into thermal energy can be harnessed to the needs of everyday people like cooking. The objective of this research is to know the energy of calor and fuel consumption that produced in combustion chamber of castel type biomass using fuel to hazelnut shell for patchouli oil distillation. This experimental method was conducted experimentally, with the main materials and equipment of combustion chamber biomass type, boiler, boiler water pipe, condenser, centrifugal blower, hazelnut shell, patchouli leaf. The working procedure is started from the combustion process inside the combustion chamber to heat the water in the boiler until distillation process to occur between dried patchouli leaves with water vapor. Then it is cooled from the coil type separator so that the vapor mixture turns phase to water mixture with patchouli oil, then the mixture is separated in the oil phase separator glass by water so that it is obtained pure patchouli oil. The results show that the combustion chamber type that is made have been in accordance with existing theoretical standards. Where the results of testing and data analysis recommend the feasibility to be applied to the patchouli oil industry. In the candlenut shell fuel of obtained heat energy of Q_f = 9.356.59 k.cal/hr with a temperature of 795 °C, while the higher heating value of 18.446 kJ/kg and lower heating value at 17.170 kJ/kg. The conclusion of this research is that besides can get good distillation technology, also can utilize existing fuel around the residence and not yet utilized in this case biomass of candlenut shell which have high calorific value for burning process in the combustion chamber.
