Taking advantage of the data from the DAS of the plant and fixing new gas temperature measure points on lower-temperature convection heating surfaces, we built the fouling monitoring model with three layers of BP neural network under the condition of observing the variation of fouling conditions for a long time, which is described by clean factor.

A method for dynamic and synthetic judgment of critical clean factors;

The effect of hot cleaning and ion cleaning for photocathode glass substrate on improving the photocathode sensitivity is researched.

The economy of optimizing soot-blowing and the selection of lower limit to clear gene C_F;
