According to the flame image which gathers from the tangential burner and the swirl burner

based on the digital image processing technology

the characteristic value significance and withdraws method are discussed

The gradation mean value and standard difference of two characteristics vectors in the flame image characteristic area are withdrawn.Applying modern artificial nerve network intelligence theory

the ART2 network algorithm is designed and improved.After the process training and the practical application

the ART2 network has the very good recognition capability to the certain operating mode eddy burner and the direct current burner flame burning condition

and the distinction is accurate

the network is stable

burning condition real-time judgement is realized.It is the good practical application effect in the scene.
