Fuel Properties of Mangosteen Pericarp Charcoal

Abstract

The objective of this research was to study the fuel properties of mangosteen pericarp (MP) and mangosteen pericarp charcoal (MPC). The rate of fuel consumption, ash content, water heating rate, heating value of fuel, elemental composition and structure were investigated. The results showed that the rate of fuel consumption of MP and MPC were 0.71±0.30 and 0.50±0.05 kg/h in average, respectively. Ash content of MP and MPC approximately was 1-3% by weight. The water heating rate of the fuels is similar in the range 2.67-3.04 ^๐C/min. Furthermore, the heating value of MP and MPC was 19,583.50±111.25 kJ/kg and 26,745.75±1,076.64 kJ/kg, respectively. Use of MPC gave appreciable increase in the content of carbon, silica and potassium from 55.30 to 61.94%, 0.22% to 0.29% and 2.02% to 10.69% by weight, respectively. Therefore, the fuel property, flammability and fertilize property of MPC was improved. Also, the MPC showed lower porosity (Higher density) than that of MP.
