Abstract
At present, energy needs are increasing almost in all sectors of human life, especially in developing countries. The world's petroleum reserves are depleting, while the need for fuel continues to increase. The use of alternative fuels can be a solution to overcome the problem of energy needs. Biomass is one of several alternative energy sources and has considerable potential to be processed into fuel and easy to obtain. Biomass raw materials can come from plantation or agricultural waste. One of the solid biomass fuels is coconut shell. Coconut shells are biomass derived from coconut plants. The use of coal as fossil fuel is also expected to replace the role of fuel oil. South Sumatra is one of the regions that have a large enough coal reserve potential in Indonesia. Co-gasification is the development of a gasification process that converts two mixtures of solid fuels such as biomass and coal by using air supply from the blower and producing a combustible gas. Therefore, this study aims to determine the effect of air mass flow rates and the fuel mixture ratios of coal and coconut shell on heat energy produced in an updraft gasifier. The research method used was experimented using an updraft type gasifier. This type is the simplest type by producing the output gas from the top. The results show that the fuel mixture ratio of coal and coconut shell as much as 20% : 80% with the air mass flow rate of 4.33 kg/h has the lowest fuel consumption rate of 2.60 kg/h. Furthermore, the fuel mixture ratio of 20% : 80% with air mass flow rate of 12.99 (kg/h) produces the biggest total heat of 1381.46 (kJ). Otherwise, the fuel mixture ratio of 10% : 90% with air mass flow rate of 4.33 (kg/h) produces the smallest total heat of 654.42 (kJ). The results also show that the fuel mixture ratio of 20%: 80% with air mass flow rate of 12.99 (kg/h) yields the highest temperatures in drying, pyrolysis, reduction and oxidation or combustion zones of 125.4 C, 156.2 C, 329.2 C and 589.0 C, respectively.
