Abstract

Indonesia annually produces significant amounts of biomass waste in the agriculture sector. Rice husk, one of the highest produced agricultural waste materials, has sufficient caloric value to produce syngas in a gasification system to generate sustainable energy. However, the production of tar from rice husk gasification is significantly high, damaging the equipment and internal combustion engine. This study carried out performance analysis on a small-scale rice husk gasifier. A simulation provided a syngas composition overview and showed a maximum LHV value of 6.47 MJ/Nm3 at ER 0.25, and a maximum CGE value of 83% at a temperature of 900 ℃. Furthermore, the economic aspect of integrating renewable technology was also considered. The gasifier had an LCOE value ranging from 0.014 to 0.089 USD/kW, depending on the use of the gasifier. The feasibility of using a mobile rice husk gasifier was also inspected, based on net present value, benefit-to-cost ratio, and payback period.

微型发电移动式稻壳气化炉性能及技术经济分析:模型与实验

印度尼西亚每年在农业部门产生大量的生物质废物。稻壳是产量最高的农业废料之一，其热值足以在气化系统中生产合成气，从而产生可持续能源。然而，稻壳气化产生的焦油产量非常高，损坏了设备和内燃机。本研究对小型稻壳气化炉进行了性能分析。模拟提供了合成气组成概述，并显示在ER 0.25时的最大LHV值为6.47MJ/Nm3，在900℃时的最大CGE值为83%。此外，还考虑了整合可再生技术的经济方面。根据气化器的用途，气化器的LCOE值在0.014至0.089美元/kW之间。从净现值、效益成本比和投资回收期等方面考察了移动式稻壳气化炉的可行性。
