摘要

火電廠鍋爐過熱器金屬管道在常規(guī)運行下疲勞失效是影響發(fā)電效率的重要因素之一。本文基于熱電廠金屬過熱器管道的失效分析報告中的實驗參數(shù)，應(yīng)用matlab的BP人工神經(jīng)網(wǎng)絡(luò)模擬功能對失效對已經(jīng)失效的管道進(jìn)行壽命檢驗。同時，通過這樣的檢驗步驟可以說明人工神經(jīng)網(wǎng)絡(luò)在此問題上比較可靠（但非精確）。

Abstract

Failure of the boiler pipes in Thermal power plant is one of the most important factors which deeply impact the efficiency of power generation in the situation of normal operation. Based on the data in the report of metal pipe failure of the power plant, the functions of simulation BP artificial neutral network (ANN) in MATLAB program are applied to verify the life of the pipe which has been broken in this paper. Meanwhile，it can be proved by the step of the experiment that ANN is relatively（but not exactly） accurate in this situation.
