分析了煤粉浓度、一次风速、冷却风、煤粉细度、燃烧器结构等主要参数对等离子点火情况的影响。介绍等离子点火技术在 2 2 0t h煤粉炉上的应用 ,为该技术在大型燃煤机组上的推广提供重要参考。
The effects of main parameters such as pulverized coal concentration, primary wind speed, cooling air, fineness of pulverized coal and burner structure on plasma ignition were analyzed. The application of plasma ignition technology on a 220t h pulverized coal fired furnace is introduced, which provides an important reference for the promotion of this technology on large coal-fired units.
