华能淮阴电厂1号炉受热面寿命评估
摘要
华能淮阴电厂1号炉于1993年11月投入运行
至2005年4月已运行约8万h。根据寿命在线检测系统的监测
采用氧化皮、硬度、组织、应力评估等方法进行检验和寿命评估。经对最严重区域有选择性割管分析表明
对流过热器冷段、高温再热器管段仍有一定的运行寿命
可继续运行一个大修期后再进行详细寿命评估。
Abstract
The title boiler had been put into operation in November
1993
having had in operation about 80000 hours to April
2005.Based on evaluation result of the online detecting system for service life
inspection and service life evaluation have been carried out by using methods
such as oxide layer
solidity
structure
and stress evaluation etc..Through selective tubecutting analysis in the most serious sections
it is shown that the cold section of convection superheater and tube section of hightemperature reheater still have certain operation life
the service life evaluation in detail can be carried out after continuous operation of one overhaul period.
