摘　　要：超临界锅炉采用不熄火不停泵的降压吹管方法是目前国内机组普遍采用的方法,而由于带循环泵的启动系统的复杂性使得吹管操作比较繁琐。目前国内普遍存在着吹管操作方法不规范的现象,对炉水循环泵安全存在严重的影响。根据某超临界锅炉的吹管工作实践,对带循环泵的启动系统的超临界锅炉吹管操作方法进行探讨,重点对吹管过程中启动系统的运行和控制方式提出具体操作方法。In boiler of supercritical non-stop off the pump and blowpipe step-down unit is currently widely used method,and because of the circulating pump with the complexity of the starting system to make blowpipe relatively cumbersome operate.At present,there is a context of the non-standard method in blowpipe,leading a serious influence on security of the circulating pump,in accordance with this article relying on a supercritical boiler of the blowpipe practice,it is about the circulating pump with the start of the supercritical boiler system blowpipe to explore methods of operation,focusing on the blowpipe of starting the process of system operation and controlling methods to give a specific operational means.
