热电偶引火监测器和红外照相系统是近年来普遍采用的火炬引火监测技术 ,但却存在着不可克服的缺点。声控火炬引火监测器以引火器的火焰头释放出的能量所产生的声音为监测源 ,可进行可靠、精确地监测 ,较之常规方法具有更多优势 :能够在火炬工作状态下进行安装与维护 ;能够获得准确的单引火器的性能和燃烧情况 ,不受天气状况的影响 ;具有快速响应能力。经过一年多的运行与测试 ,该声学监测系统未出现任何故障 ,与热电偶相比 ,可节省资金 Thermocouple pilot monitor and infrared camera system are widely used in recent years, torch pilot fire detection technology, but there are insurmountable shortcomings. Voice-activated torch pilot monitors the source of energy from the flame front of a pilot as a source of monitoring for reliable and accurate monitoring, with many advantages over conventional methods: Installation and maintenance during torch operation ; To obtain accurate single igniter performance and combustion conditions, free from the impact of weather conditions; with rapid response capability. After more than a year of operation and testing, the acoustic monitoring system did not show any failures, saving money compared to thermocouples
