一种电厂燃气锅炉火焰检测装置
摘要：
本发明公开了一种电厂燃气锅炉火焰检测装置，包括火焰离子电流采集系统、LED显示及报警系统和输出系统；火焰离子电流采集系统采集到的离子电流信号，分别传输至LED显示及报警系统和输出系统。本装置采用通过检测燃气燃烧过程中产生的离子电流，离子电流大小判断火焰燃烧程度。其检测准确度高，同时输出有源的4～20mA模拟量和报警开关量信号送入DCS控制系统，方便控制人员通过模拟量和开关量来判断燃烧的状况，LED显示方便巡检人员观测火焰燃烧程度；通过试验效果良好且应用稳定可靠。
摘要（英）：

The invention discloses a power plant gas boiler flame detection device. The power plant gas boiler flame detection device comprises a flame ion current collection system, an LED display and alarm system and an output system. Ion current signals collected by the flame ion current collection system are respectively transmitted to the LED display and alarm system and the output system. According to the invention, an ion current generated in a gas combustion process is detected, and the flame combustion degree is judged according to the magnitude of the ion current. The detection accuracy is high, and active 4-20 mA analog quantity and an alarm switching value signals are simultaneously output and sent to a DCS control system, control personnel can conveniently judge the combustion state according to the analog quantity and the switching value, and inspection personnel can conveniently observe the flame combustion degree by means of LED displaying; in addition, by means of experiments, the effect is good, and the application is stable and reliable.
