摘　　要：稳压冲管技术成熟对超超临界机组调试具有重要意义。介绍了某电厂3100 t/h直流锅炉稳压冲管过程、参数选择和注意事项。实践表明,通过优化运行方式,并尽早投入精处理系统以回收锅炉疏水,可以较好实现稳压冲管。在稳压冲管期间,锅炉入炉煤量130 t/h,补水量1100 t/h,过热器冲管系数可达1.25。检验靶板表明,冲管效果良好。Stable-pressure steam purging is of great significance to debug ultra supercritical boiler. The Stable-pressure steam purging process, purging parameters and points of attention for 3100t/h boiler in certain power plant were introduced. The results show that optimizing operation mode and putting the fine chemical processing system as early as possible to reclaim drain water could complete stable-pressure steam purging greatly. In the process of stable-pressure steam purging, the coal quantity of boiler is 130t/h, filling water is 1100t/h,the superheater coefficients can reach 1.25. The results of inspecting target plate show that the effect of stable-pressure steam purging is great.
