摘要
根据煤粉燃烧理论及数字图像处理技术 ,提出用“投影火焰锋面存在”、“投影火焰锋面位置的窜动”以及“投影火焰锋面平均梯度值的变化”三个条件来诊断燃烧器火焰的ON/OFF状态 。
On the basis of pulverized coal combustion theory and digital image processing technology proposed is a method for the diagnosis of the on/off status of a burner flame. The method features three conditions, namely, the presence of a projection flame front, the irregular shifting motion of the latter's location, the variation of the latter's average gradient value. With the help of the above method it is possible to guide combustion operations and help FSSS (furnace safeguard supervisory system) to ensure furnace safety protection.
