介绍了在南市电厂２２０ｔ／ｈ 锅炉瘦高形炉膛内燃用高挥发分烟煤（ 朔州煤） 时试验研究情况。三周的实炉试验运行结果表明，根据燃煤收到基挥发分及灰熔点结渣指数等具体特点，及时调整好运行参数，确保火焰中心位置合理，并加强吹灰，在瘦高形炉膛内燃用高挥发分烟煤时曾出现过的塌焦熄火问题可以得到解决；高挥发分朔州煤可以在瘦高形炉膛内安全可靠运行，且燃烧效率还会有所提高。
The experimental research on the high volatile bituminous coal (Shuozhou coal) in the 220 t / h boiler lean high profile hearth in Nanshi Power Plant was introduced. Three weeks of actual furnace test results show that according to the coal-fired base received volatile and ash melting point of the slagging index and other specific characteristics, timely adjustment of the operating parameters to ensure that the flame center position and strengthen the soot blowing, The problem of collapsing and flameout that occurred in high volatile bituminous coal for internal combustion can be solved. The high volatile Shuozhou coal can operate safely and reliably in the lean, high-profile hearth and the combustion efficiency will be improved.
