摘要：
低挥发分水煤浆比精煤水煤浆在价格上有明显的优势，在锅炉上燃用水煤浆除考虑着火和燃烧稳定性外，结渣特性是另一重要的影响锅炉安全经济运行的因素。文中就大型锅炉燃烧低挥发分水煤浆，利用硅碳棒进行结渣试验，采用单一结渣指标，通过对渣层厚度、沉积量和沉积速率的变化分析及X–射线衍射图谱和扫描电镜分析，模糊综合评判模型，获得低挥发分水煤浆燃烧结渣特性。结果表明，低挥发分水煤浆的结渣情况在可接受的范围内。 |

Abstract:
Low-volatile coal water slurry (CWS) has an advantage over washed coal CWS in price obviously. When CWS is applied in a boiler, besides the stability of inflammation and combustion, slagging characteristic is another important factor to affect safety and economy in operation of the boiler. Low-volatile CWS was used in large-scale boilers and slagging experiment was processed using silicon carbide rods. This paper used coal ash analysis, changing tendency of slag thickness, mass and deposition rate , X-ray diffractometer (XRD) and scanning electron microscope (SEM), a slagging characteristic decision model based on fuzzing mathematics to predict the slagging, and get the slagging characteristic of low-volatile CWS. The result indicates that the slagging of low-volatile CWS is in an acceptable extent. |
