Intelligent optimizing control used in combustion of boiler

In order to improve the combustion efficiency of boilers, the self-optimizing approach which takes the furnace temperature as the major signal to control the ratio of wind to coal input is used to save energy. This method can be used to replace the one which uses zirconia as monitor, so that the shortcomings like expensive, ephemeral, and hysteric can be avoided. Equal step by step self-optimizing algorithm and variant step algorithm are introduced. The intelligent self-optimizing control algorithm is realized by fuzzy logic estimation method.
