摘要： This invention relates to the supervision of a combustion state of a combustion furnace. A flame formed concentrically with the direction of a fuel jetted from a burner being the center is measured from its side, and two oxidizing flame zones as high luminance zones are extracted. Using the shape parameters of the flame, an index for reducing NOx and unburnt components in ash are calculated and estimated so as to supervise the combustion state. The positions or centroids of the flames and the distance between the centroids are used as the shape parameters, and the flame shape is divided into two zones for easy display of each zone.

The information transfer control refers to information in the reference information storage, and rearranges the information arrangement from the transferer subsystem to an information arrangement suitable for the transferee subsystem, if necessary, followed by transferring it. The subsystem can be changed easily by adding, deleting or correcting the reference information in the reference information storage. The configuration of the transfer control system is therefore flexible.
