摘要
锅炉中煤粉的燃烧过程是非常复杂的悬浮燃烧且极不稳定 ,监视系统的图像可能受到各种噪声的干扰 ,文中详细介绍了消除图像噪声、图像增强及边缘检测的原理 ,实现了对火焰图像的处理 ;给出了基于维恩辐射定律导出的双色测温计算火焰温度的算法 ,并成功用于火焰温度场的计算 ;最后给出了温度场计算机显示原理。图 5参
Combustion of coal powder in boiler is a kind of complex suspension and unstable, monitoring system image includes a lot of noise signals from difference hands. The principle of elimination image noise, enhancement image and boundary detection are discussed in detail, processing for flame im age is completed. The colorimetric arithetic calculating flame temperature based on Wien theorem in radicalization is demonstrated, and is used to calculate on temperature field successfully. The display principle of flame temperature field on computer is discussed. Figs 5 and refs 6.
