In the face of the increasingly tense energy, energy conservation has become scientific and technological progress and social development of a theme. The growing industrial development, environmental protection has become a common concern in the world, the issue is Shuangliao Power Plant Unit One technological innovation projects, "one unit to optimize combustion control system" in the background, one of the main ways to improve Efficiency of the boiler unit.State power companies, "energy-saving, environmental protection," taking it very seriously. China's electric power companies in the technical level, management level is still relatively extensive, there is great potential for energy conservation. Energy efficiency is low restricting China's economic and social development of the prominent contradictions. Do not save energy, energy efficiency, the merely rely on increased energy construction methods can not fundamentally solve the energy problem. This requires constant energy potential, a path with Chinese characteristics-saving development. The subject of this research is to improve the efficiency of the boiler combustion in the energy efficiency has improved in the energy-saving power generation will have very meaningful.In recent years, with industry and the rapid development of economy, industry and electricity for civilian power consumption increase over the years, power companies increased coal consumption volume, the atmosphere of emissions is to improve, the state's electricity generating enterprises coal consumption Demanding lower emissions of pollutants more stringent requirements, so as power companies on the one hand, economic efficiency requirements, environmental protection requirements on the one hand, the two complement each other and therefore increase the efficiency of the boiler combustion imminent.In this paper, power plants Shuangliao One furnace combustion system for the study, Shuangliao how to improve the combustion efficiency of the furnace One plant is an important research is the realization of fuzzy control in the actual subject of the application of a very successful example. For the boiler combustion system lags behind big, serious non-linear features in the boiler load control circuit used in Fuzzy-PI dual-mode controller, that is, in the conventional control system to control and intelligent control co-exist.The present system of gas than the on-line self-optimizing functions, according to the boiler flue gas in the CO and O2 concentration of large and small, fuzzy optimization controller to adjust the ratio of gas to maintain the boiler in the best working conditions. In order to arrive at a reasonable control program, the author and colleagues to find a great deal of information in foreign languages, for analysis and discussion, select the most suitable control scheme. In order to verify this control scheme of rationality and effectiveness of this article have done a lot of simulation studies. The article on a variety of programs to control compared to the selected program to control a detailed theoretical analysis and simulation test, proof of its legitimacy. From the simulation results, we can see that with more from adjusted non-self-adjusted fuzzy controller to control the more stable than the two-fuzzy controller fuzzy controller to control the more stable, and by selecting the switch can switch controlled manner. Input from the effects of view, this input to optimize combustion control system after the boiler combustion efficiency has improved remarkably. I plant for the next crew of three other combustion optimization provides a theoretical basis and practical experience.In this paper, using methods from theory to practice, from theory to practice and theory practice. Theory, initially established to optimize combustion control theory, mathematical models and simulation, to find burning Unit impact on the efficiency of low-key factor, and analysis. Practice, according to the design of the control loop to achieve, according to the results of theoretical analysis, monitoring and optimization of the combustion system software configuration. Then, the test data and theoretical analysis of the results of the comparison will be put into pre-and post-boiler efficiency comparison. And then sum up the optimization of combustion systems.This paper reads as follows:1. Introduced the boiler combustion optimization of the current situation and prospects.2. To study the key issue: to optimize combustion control method of choice.3. Chosen for the optimization of combustion systems simulation.4. Boiler operation of the main parameters of the monitoring.5. Boiler on-line monitoring system software configuration.6. Combustion control system to optimize the configuration software.7. Finally, on the basis of summing up the full text, pointing out that a number of pending further in-depth study and recommendations to solve the problem.
