ABSTRACT

The effect of cofiring elaeis guineensis residues with coal pellets for power generation was investigated. Samples of elaeis guineensis residues (palm kernel shell (PKS), palm fiber (PF) and empty fruit bunch (EFB)), and coal were collected and pulverized. The pellets were thereafter produced mechanically, using an optimized mixing ratio of 80:20. Coal palm kernel shell (CPKS), coal palm fiber (CPF), coal empty fruit bunch (CEFB), and coal (C) pellets were thereafter produced and characterized in accordance with the ASTM standard. Results obtained show that the caloric values of CPKS, CPF, CEFB, and C pellet were 28033 kJ/kg, 27695 kJ/kg, 27687 kJ/kg and 22021 kJ/kg, respectively. While the % ash was 11.15%, 12.97%, 12.75%, 14.89%; % sulfur was 0.7%, 0.71%, 0.73% and 0.76% for CPKS, CPF, CEFB, and C, respectively. Four case scenarios; A (raw biomass without power generation), B (raw biomass with power generation), C (raw biomass converted to pellets) and D (raw biomass blended with coal pellets) were compared. Case D was found to have the highest power generation potential and energy utilization efficiency of 3.378 MW and 84.43%, respectively. Cofiring of elaeis guineensis residues with the coal pellets, reduced percentage ash and sulfur contents of combusted pure coal.

摘要

研究了用煤球团共烧 elaeis guineensis残渣发电的效果。elaeis guineensis样品收集并粉碎残留物（棕榈仁壳（PKS）、棕榈纤维（PF）和空果串（EFB））和煤。之后使用优化的 80:20 混合比以机械方式生产颗粒。此后根据 ASTM 标准生产和表征煤棕榈仁壳 (CPKS)、煤棕榈纤维 (CPF)、煤空果串 (CEFB) 和煤 (C) 颗粒。结果表明，CPKS、CPF、CEFB和C颗粒的热值分别为28033 kJ/kg、27695 kJ/kg、27687 kJ/kg和22021 kJ/kg。而%灰分分别为11.15%、12.97%、12.75%、14.89%；CPKS、CPF、CEFB 和 C 的硫含量分别为 0.7%、0.71%、0.73% 和 0.76%。四个案例场景；A（未发电的生物质），B（发电的生物质），比较了 C（转化为颗粒的原始生物质）和 D（与煤颗粒混合的原始生物质）。案例 D 的发电潜力和能源利用效率最高，分别为 3.378 兆瓦和 84.43%。共烧elaeis guineensis残留物与煤球团，降低燃烧纯煤的灰分和硫含量百分比。
