摘要

针对某电厂1号锅炉末级过热器奥氏体不锈钢管爆管问题

通过宏观检验、金相检验和氧化皮检测

确定其主要由钢管内壁氧化皮脱落堵塞所致。对此提出了严格控制蒸汽和锅炉部件金属温度及严格进行蒸汽冲洗

适当提高机组升降负荷速度

并利用氧化皮检测技术进行针对性检测等措施

保证锅炉运行安全。

Abstract

Directing against tube-burst problem of austenitic stainless steel pipe in final stage superheater of boiler no.1 in one power plant

it is believed that the main cause to be peel-off of oxide skin from inernal wall of steel pipe and blockage in the said tube through macroscopic examination

metallurgical analysis and oxide skin inspection. For this

some measures have been put forward

including: strictly controlling metal temperature of turbine and boiler parts; blowing out with steam; suitably enhancing the speed of increasing or decreasing the load of unit; carrying out aimed detection by using oxide skin detecting technology etc.

to ensure the safety of operation.
