【摘要】 分析了混煤的热天平实验数据．认为两种着火特性相差很大的煤混烧，混煤的着火温度只取决于最着火的煤，进一步分析了混煤煤粉气流的着火温度变化是由于混煤比例变化导致易着火煤的煤粉浓度发生了变化。更多还原

【Abstract】 The ignition characteristics of coal blends are studied in details by thermgravimetric analysis The parent coal that is ignited easier detemines the ignition temperature of blend. Therefore, the conclusion can be resulted that the ignition temperature of the mixed flow of pulverized coal blends and air is detemined by the concentration of the perent coal with easier ignition characteristic.更多还原
