Design And Implementation Of Power Plant Boiler Combustion Optimization Control System

This paper reviews power plant combustion optimization control system, the paper summarized the research status and development trend at home and abroad, introduces theoretically the plant combustion optimization of real-time data acquisition, dynamic control algorithm and the key technology of network, especially for several kinds of commonly used data acquisition technology has carried on the detailed research, description and analysis of the function of each acquisition corresponding principle and technology, in addition, also the key terms of data collection technology for the professional interpretation.Combining with the trend of the development of the domestic power plant combustion optimization, design in datong second power plant(company) 7 units of boiler combustion optimization control system requirements.First, to increase the balance valve automatic control to ensure balanced combustion boiler, analyzes the composition of the original boiler combustion system, through the analysis of its key to design can be integrated into the original system of optimizing the structure of control system.Secondly, the optimal control rules in alternative current feedback control, on the new structure optimized by closed-loop control to achieve the primary and secondary wind pressure, the secondary air distribution optimization control direct optimization of automatic control and reduction of warm water.Finally, comparing the combustion optimizing control closed-loop input data and the typical conditions before and after the overall situation, expounds the effect to improve the effect of unit operation, reliability, and technical supervision effect and economic benefits of the role of, illustrates the combustion optimizing control system to achieve the effect of energy saving of the boiler.
