摘要

摘要: 压块成型技术常用于生物质和煤炭燃料领域，成型后的燃料具有易于运输和储存、能量密度高的特点。煤气化细渣作为一种含碳量高的煤基固体废弃物，具有可观的应用潜力。研究将煤气化细渣与生物质耦合，制备厘米级压块燃料。压块燃料为在6 MPa下室温环境中，经过2 min压制而成。利用自主研发的平焰宏观热重燃烧反应器，以高加热速率的高温烟气模拟实际燃烧工况，主要关注不同生物质种类及生物质掺混比例（0%~100%）对压块燃料燃烧及排放的影响。实验结果表明：不同生物质因化学组分差异，显著影响燃烧过程。引入生物质这一过程通过改变燃料颗粒组分，可以显著提升单一原料种类颗粒的燃烧速率，挥发分燃烧速率相差可达3~5倍；并可以降低混合燃料燃烧过程中NO _x和CO的生成量，污染物生成量可降低50%以上。该研究成果为煤气化细渣与生物质耦合制备清洁高效固体燃料的工艺优化提供了关键实验支撑。

Abstract: Pelletizing technology has been widely used in the field of biomass and coal fuel processing. Pelletized fuel offers advantages such as easy transportation and storage， as well as high energy density. Coal gasification fine slag， a carbon-rich coal-based solid waste， holds considerable application potential. In this study， gasification fine slag was blended with biomass to prepare centimeter-scale composite pellets. The pelletized fuels were formed under a pressing pressure of 6 MPa at room temperature for 2 minutes. A self-developed flat-flame macro-thermogravimetric combustion reactor was employed to simulate practical combustion conditions using high-temperature flue gas at high heating rates. This study focused on the effects of different biomass types and blending ratios （0 to 100%） on the combustion characteristics and emission behavior of the pelletized fuel. The experimental results demonstrated that differences in the chemical composition of biomass types significantly influenced the combustion process. Furthermore， the introduction of biomass modified the fuel particle composition， which markedly enhanced the combustion rate of single-component fuel particles and reduced NO _x and CO emissions during co-combustion of the blended fuel. These findings provide critical experimental support for the optimization of clean and efficient solid fuel production through the coupling of gasification fine slag and biomass.
