ANALISIS EKSERGI PADA GASIFIKASI BIOMASSA001
The need for electrical energy in Indonesia increases in the future. Currently, Indonesia relies on fossil-based energy resources, such as crude oil and coal. These energy resources decrease from time to time. Thus, new and renewable energy resources are important to support the energy transition toward cleaner and sustainable energy. Biomass gasification refers to a method of creating sustainable-alternative energy resources. Biomass gasification is a process to improve the contained energy on biomass by converting the biomass into gas to burn. The implementation of this process applies incomplete combustion inside of a gasifier. This process produces flammable gases, hydrogen (H), carbon monoxide (CO), and methane (CH4). These gases are useful for power plant fuels. This research applied the exergy analysis method of the first and second laws of thermodynamics. The applied analysis was accurate to measure the efficiency values and exergy destruction of the system. The researcher used a secondary data source to examine the gasification process with the downdraft-type gasifier and hazelnut shell fuels. The researcher applied three comparative ratios of air to fuel, AFR. The first AFR was 1.63 with a fuel mass flow of 1.73kg/h. The second AFR was 1.52 with a fuel mass flow rate of 2.64 kg/h. Then, the third AFR was 1.51 with a fuel mass flow rate of 3.69 kg/h. These three AFRs led to different percentages total of product gas, charcoal, ash, and tar. The exergy calculations of the gasification process with AFR 1.51 and fuel mass flow rate of 3.69 showed the most optimum gasification operation of the other AFRs. The exergy result of the product gas was 8.635 kW with an exergy efficiency of 43.5% and exergy destruction of 10,036 kW
