摘　　要：通过在试验室条件下对神华煤与其它烟煤混煤的掺烧试验,掌握了神华煤掺入不同比例其它煤后,混煤的着火、燃尽和结渣性能及沾污性能的变化规律。同时,进行了炉内气氛条件对结渣的影响试验。在试验数据的基础上,总结了混煤结渣指数与煤灰软化温度和煤灰碱酸比的定量关系。试验结果可为电厂锅炉掺烧神华煤或减缓燃烧神华煤的结渣问题提供指导。Through test of mixedly burning shenhua coal with other bituminous coals in laboratory condition,the regularity of variation in ignition,burnout,as well as slagging behavior and contamination after mixedly burning shenhua coal with other bituminous coals in different ratios has been grasped.At the same time,the influence of atmosphere condition in the furnace upon slagging has also been tested.On the basis of tested data,the quantitative relationship between slagging index of the blend coal and softening temperature of coal ash,as well as the alkali-acid ratio of the coal ash has been summarized.The test results can provide with guidance for mixedly burning shenhua coal or for alleviating the slagging problem in burning shenhua coal.
