摘要
通过对高压加热器的静态仿真计算,分析了高压加热器泄漏对其运行参数,如给水出口温度、抽汽管道压损、疏水温度的影响。根据分析结果,提取了高压加热器泄漏故障的特征量,为建立高压加热器故障知识库并对其进行泄漏故障的早期诊断奠定了基础。
Through static emulating calculation of the highpressure heater,the influence of highpressure heater leakage upon its operation paeameters,such as outlet temperature of the feedwater,pressure loss of the steam extraction pipeline,and temperature of the drain,has been analysed.On the basis of analysis results,eigenvalues characterizing fault of highpressure heater leakage have been picked up,laying a foundation for knowledge base of the highpressure heater faults and for early diagnosis for its leakage faults.
