摘要

根据超超临界1 000MW机组螺旋管圈塔式锅炉的特点

增加临时补水系统采用稳压吹管方式进行吹管。实际运行结果表明

锅炉稳压吹管连续2次靶板冲击斑痕粒度等于小于0.8mm

且斑痕不多于8点

质量符合《工程建设标准强制性条文》(电力工程部分)的要求

吹管质量优良

可供同类机组参考。

Abstract

Based on the features of spiral-tube coil tower type boiler

and installing temporary make-up water system

the pipe-blowing using stable-pressure steam for ultra-supercritical 1000 MW unit has been selected.Results of practical operation show that the pipe-blowing of said mode for successive two times makes the flushed spots on target plate being equivalent to or smaller than 0.8 mm

and the number of spots isn't more than 8 points

the quality of pipe-blowing is excellent

being able to be used for reference to similar generating units.
