摘　　要：汽水系统作为锅炉水汽转换及输送的重要单元,长时间在高温高压环境下工作,受高温腐蚀及烟气磨损的影响,汽水系统极易发生故障,是锅炉安全运行的薄弱环节,为提高锅炉长期稳定运转率,提升锅炉运维效率,基于DCS系统和故障树分析方法,开发出基于故障树的故障诊断系统软件,实现了锅炉汽水系统的实时监测,智能故障诊断。Boiler steam-water system as a vapor conversion and transport of significant elements,work long hours under high temperature and pressure,high temperature affected corrosion and wear of the flue gas,boiler steam-water system vulnerable to failure,the weak link in the safe operation of the boiler.This paper analyzes the impact of various elements of the system safe and stable operation of boiler steam-water system,and failure mechanisms studied by fault tree analysis method was established fault diagnosis system based on fault tree.Finally,the use of VB,MYSQL and other development tools to develop a software-based fault diagnosis system fault tree.
