This paper mainly introduces the extraction methods about the boiler flame area of boundary layer. Using the binarization arithmetics, CCD image data will become a binary 2 direction matrix. Based on the ARM of the system speed processing, ARM will extraction the boiler flame area boundary layer position. Unexploded area, Fire area, Combustion area of the boundary layer are the digital image by circle...
The ball mill pulverizing system with multi-variable, strong coupLing, large inertia and time-varying etc characteristics, long-term since difficult to input automatic control, therefore become electric power industry automatic control research hot spot problems. This paper studied and analyzed in detail the working principle of the ball mill pulverizing system and work characteristics, using multiple...
To obtain perfect performances of the main steam temperature control system, a new scheme is proposed. The scheme substitutes fuzzy self-tuning PID controller for the main regulator of cascade control system. The controller is composed of fuzzy controller and PID controller. According to the error and error rate of the control system and fuzzy control rules, the fuzzy controller can online adjust...
A combustion optimizing model based on RBF neural networks is set up, and the optimizations of providing coal volume and real generating electricity power are actualized. At the same time, the simulation model is established by MATLAB. The simulation research is processed. The simulation result indicates: in the stabilization state, if the boiler load, power plant coal character (the distinctness...
A new on-line measurement approach for coal storage in ball mill is presented in this paper. In the approach, fuzzy neural network modeling is adopted to construct the measurement model for coal storage in ball mill. During the modeling, fuzzy neural network model is employed to approximate the non-linearity of coal storage in ball mill. Speed of coal speed, sirocco flux, recycles wind flux, export...
