Abstract

The invention provides a pulverized coal burner ignition stability analysis method and device, and the method comprises the steps: decomposing a flame radiation spectrum in a pulverized coal burner into three primary colors through a color filter layer, and converting the three primary colors into digital image data in direct proportion to the light intensity; a flame radiation intensity signal is obtained through analysis according to the digital image data, and flame image temperature data is obtained through calculation according to the flame radiation intensity signal through the corresponding relation between the temperature and the image and the Planck law; and obtaining a combustion stability analysis result through binarization processing according to the flame image temperature data. Therefore, the flame stability is judged by utilizing the color distribution signal of the flame image, so that the accuracy of stability judgment is effectively improved; and meanwhile, the process is relatively simple, and the applicability is relatively high.

Description

technical field [0001] The application relates to the field of safety monitoring, in particular to a method and device for analyzing the ignition stability of a pulverized coal burner. Background technique [0002] Flame image temperature processing technology is a two-dimensional temperature measurement system based on image acquisition and image processing, which can realize simultaneous online display of flame image and temperature, and is widely used in coal-fired boilers, gas-fired boilers, and steel, chemical, cement and other industries kiln. In recent years, with the continuous development of computer and image processing technology, the flame image resolution and temperature measurement accuracy have also been continuously improved, and the basic conditions for using the flame image temperature as the ignition stability criterion have been met. In these technologies, image brightness and flicker frequency are mainly used as the main judgment basis. However, these m...
