【摘要】 针对蒙西地区火力发电厂所使用煤种，选取三个典型电厂采集煤样，研究其着火点、燃烬温度、燃烧速率等燃烧特性参数。研究表明，着火点主要与煤的挥发分含量相关，挥发分含量越高，其着火点越低；燃烬温度主要与煤的焦碳含量相关，煤的焦碳含量越高，其燃烬温度越高；煤的燃烧速率与煤的含碳量呈正相关，与其灰分含量成负相关，其中煤的含碳量越高，其燃烧速率越大，煤的灰分含量越高，燃烧速率越小。更多还原

【Abstract】 According to the coal types used by thermal power plants in Mengxi area, three typical power plants are selected to collect coal samples, and the combustion characteristics parameters such as ignition point, burning temperature and burning rate of coal samples are studied. The results show that the ignition point is mainly related to the volatile content of coal. The higher the volatile content is, the lower the ignition point is. The burning temperature is mainly related to the coke content of coal. The higher the coke content of coal, the higher the burning temperature. The combustion rate of coal is positively correlated with the carbon content of coal, and negatively correlated with the ash content of coal. The higher the carbon content of coal, the higher the combustion rate, the higher the ash content of coal, the smaller the combustion rate.更多还原
