摘　　要：为了满足能源与动力工程专业实验教学对燃烧检测平台的需求,设计了一套基于主被动协同检测的碳氢火焰多参数检测系统。该系统依托电荷耦合成像相机与激光发射器的同步测量,通过自行开发的图像处理程序开展数据采集与处理,结合热辐射定律与双色法等原理获得火焰介质辐射强度、透射比、线性吸收系数、燃烧温度等多个参数。在具体应用方面,通过激光消光测量实现火焰温度和辐射特性参数的解耦,将求解得到的线性吸收系数与图像检测获得的火焰辐射强度联立进而得到火焰介质温度分布。此系统能满足碳氢燃料燃烧火焰检测需求,对现有实验教学体系进行了扩充和完善。In order to meet the needs of experimental teaching in the field of energy and power engineering for a combustion detection platform,a set of carbonhydrogen flame multiparameter detection system based on active and passive cooperative detection has beenis designed.This system relies on the synchronized measurement of a chargecoupled device and a laser emitter.Data collection and processing are carried out through a selfdeveloped image processing program.By combining principles such as thermal radiation law and twocolor method,parameters such as flame medium radiation intensity,transmittance,absorption coefficient,and combustion temperature are obtained.In specific applications,the decoupling of flame temperature and radiation characteristic parameters is achieved through laser extinction measurements.By combining the calculated absorption coefficient with the measured flame radiation intensity,the flame temperature distribution can be obtained.In terms of experimental teaching applications,it can be used to reconstruct multiple gas sources,operating conditions,and parameters for hydrocarbon fuels such as ethylene.The reconstruction results have beenare verified to be feasible through experiments,meeting the combustion flame detection requirements of hydrocarbon fuels,and expanding and improving the existing experimental teaching system.
