智能紫外火焰检测器的研究

Intelligent Ultraviolet Flame Detector

注汽锅炉是产生蒸汽的主要设备,它以原油为燃料。火焰检测器用来实时监测燃烧器喷嘴火焰状态,为确保锅炉连续安全运行提供保障,对锅炉安全运行有着重要的实际意义。一种基于单片机控制的智能火焰检测器可以检测火焰发出的紫外线信号,输出4-20m A电流信号,为锅炉安全监测系统提供燃烧器喷嘴火焰强度信号。

Steam injection boiler is the main equipment of generating steam, using crude oil as fuel. Flame detector is used for real-time monitoring of the burner nozzle flame state, to guarantee the safe operation of the boiler, which has the important practical significance . The intelligent flame detector based on single-chip microcomputer control, can detect ultraviolet signal from the fire, and output the 4-20mA current signal, providing the burner nozzle flame intensity signal for boiler safety monitoring system.
