摘要

芦竹作为一种高能低灰的草本生物质燃料，具备良好的协同掺烧潜力。为探究其对燃煤灰分行为的影响，在沉降炉平台上开展了芦竹与神木煤、大混煤的混烧实验，结合XRF、SEM-EDS、XPS与灰熔点测试，系统分析了不同掺混比例与温度条件下灰分的组成演化、结构特征及K元素赋存状态。结果表明：芦竹掺烧显著提高灰分中K、Cl、S等低熔组分比例，增强结渣倾向，且在大混煤体系中更为明显；升温有助于K元素由K2SO4向KAlSiO4等稳定结构转化，灰分趋于致密化；神木煤灰以Si-Al骨架为主，结构稳定性与抗结渣性能更强。

Abstract

As a herbaceous biomass fuel with high energy content and low ash yield

Arundo donax (AD) exhibits strong potential for synergistic co-firing. To investigate ash evolution and slagging behavior during its co-combustion

experiments were conducted using a laboratory-scale drop-tube furnace with AD blended with Shenmu coal and ordinary mixed coal. Combined with XRF

SEM-EDS

XPS

and ash fusion temperature measurements

the composition evolution

structural characteristics

and potassium occurrence states of the ash were systematically analyzed under different blending ratios and temperatures. Results indicate that the addition of AD significantly increases the proportion of lowmelting components such as K

and S in the ash

thereby enhancing slagging tendency

with a more pronounced effect in the ordinary mixed coal system. Elevated temperature promotes the transformation of K species from K2SO4 to more stable structures like KAlSiO4

and the ash tends to be densification. Shenmu coal ash

dominated by a SiAl skeleton

exhibits stronger structural stability and better resistance to slagging.
