电站锅炉采用工业电视直接观察炉膛火焰图像,从火焰表面特征判断当前锅炉燃烧状态。针对燃烧过程的动态特性和各种随机干扰,本文对炉膛火焰数字图像进行了滤波和增强显示等处理,并具体讲述了各种处理的MATLAB 实现,突出了图像中感兴趣的特征,更有利于对火焰的燃烧状进行观察,对其在电厂锅炉炉膛火焰检测的应用这一领域做了有益的探索。关键词:炉膛火焰;图像处理;MATLABAbstract:Electricity station boiler using industry TV observes furnace flamedirectly, than judging the boiler burning situation by the flame appearancescharacter. According to dynamic characteristic of combustion and variousdisturbances, this paper process the hearth flame digital images with filtrate andenhance display,and tells us how to process the image by using MATLAB, givesprominence to the interested character in the images. This paper is also in favorof the observation of flame combustion, makes a good explore in the domain of boilerhearth flame examination.Keywords: furnace flame; image processing; MATLAB
