| 摘 要： | 锅炉受热面结渣问题是影响锅炉正常运行的重要因素之一。采用测量不同碳含量的神木煤灰样的特性温度和结渣强度以及对试样的XRD物相分析,研究残碳对煤灰结渣特性的影响规律。发现碳含量为1%或高于15%时使神木煤灰样的灰熔点明显提高,同时含碳8%以上也引起结渣的剪切强度下降。所以,通过控制灰渣中的碳含量可以缓解结渣,并使其容易清除。

| Abstract: | The wall slagging is an important factor that can disturb boiler run well. To find out what influence the unburned carbon can make for the slagging, we measure the characteristic temperature and the shear intensity of the ShenMu coal sample, which contain different amount of carbon and analyze these samples by XRD. The result shows that containing 1% or more than 15% of carbon can increase the melting point and containing more than 8% carbon can reduce the shear intensity of the ShenMu coal. So we can lighten slagging and make slag clearing easily by control the content of unburned carbon in the ash. |
