等离子燃烧器筒壁温超温研究

摘要

针对山西某发电厂600 MW超临界发电机组点火初期，等离子燃烧器筒壁超温和挥发分低、着火困难的问题，提出一些燃烧调整措施，如更换燃烧器中心筒、改变磨煤机入口一次风风压、分离器出口温度、降低等离子拉弧电流等，得出适合该厂的运行方式。%It was difficult for a 600 MW supercritical generating set located in a certain power plant to be ignited due to over-temperature of plasma burner wall and low fugitive constituent. Then,some adjustment methods were put forward,like replacing the core tube of the burner,adjusting the primary air wind pressure,lowering the plasma arc current,etc.,so that the suitable operation mode for the power plant was concluded.
