| 摘 要： | 概述了火电厂燃煤锅炉真假灭火事故的特征,分析了锅炉假灭火事故产生的主要原因即火焰检测(以下简称火检)误判断产生的原因,提出通过调整火检的检测位置来消除火检误判断由此解决锅炉假灭火事故的观点,并对其可行性与安全性进行了论证,通过某电厂的实践研究证实:调整火检的检测位置是一条安全可靠的技术措施,可有效减少甚至消除火检的误判,进而减少稳燃用油,预防由误判使灭火保护系统动作造成锅炉假灭火事故的发生。

| Abstract: | This paper analyzed the main causes of false boiler flame extinction through theory analysis and the test of existing boiler,proposed the technology measures to clear the false deduction from flame detector by adjusting the supervisory position of flame detector and verified the feasibility and safety.The practical application indicates that regulating the detecting position is safe and reliable to avoid the false deduction effectively,reduce the amount of the combustion stabilizing oil and prevent the flame extinction resulted from the false deduction of flame detector and the flame protection system.. |
