| 摘 要： | 该文在磨煤机出力变化时，进行了优化分离器转速和一次风量的试验。试验发现：当磨煤机出力为12kg／s时，建议分离器转速为85r／min、风粉比为2．0；当磨煤机出力为8kg／s时，建议分离器转速为70r／min、风粉比为2．5。文中得出的风／粉比和分离器转速／给煤量曲线可以指导磨煤机的运行。 |

| Abstract: | The experimental research has been done to optimize classifier speed of pulverized coal milling system and primary air flow rate of the boiler when the system load is varied. The results show that: when the mill load is 12 kg/s, the recommended classifier speed is 85 r/min and the ratio of air to pulverized coal is 2.0 in mass; when the mill load is 8 kg/s, the recommended classifier speed is 70 r/min and the ratio of air to pulverized coal is 2.5 in mass. The conclusion of the in mass pulverized coal, the curve for classifier speed/coal capacity, both can be used as the guidance for milling system operating. |
