The Study Of On Line Intelligence Monitor And Optimization In Boiler Combustion

The foursquare contact circle and boiler is one of the important equipments in power plant. To improve its security and economy, the inner combustion process and its temperature field, velocity field etc. must be deeply studied detailed. Many factors those affecting them, initiate a lot of problems, such as low boiler efficiency, short safe periodicity, accident frequently and so forth unexpected harmful effects. The current experiment monitors are high with low effect. Therefore, it is necessary that the various working condition and scheme should be carried out the relevance numerical simulation computation on the boiler and monitored on line.The main work of this paper with so-and-so heating and power plant, the foursquare contact circle and coal powder boiler in 670t/h is an object of study combine with CFD and software named Delphi that faces to object, geared to the needs of programming software and data collect module interface technological developing out intelligence monitor system operation platform. It is composed of two parts master control system and arithmetic system. Master control system adopted Windows API interface technology, controls the operation progress. With nowadays national upper comparatively advanced numerical technology to be center arithmetic procedure, makes use of the interface technology to realize the data acquisition and exchange. It is combined with microelectronics technology, computer art and automation measurement and data processing. The inner combustion produced velocity field, temperature field, pressure field, the distribution of different components, and the polluted creation is simulated accurately.By installation and testing in the power plant, collecting abundant data carries out compressive analysis. It has analyzed boiler inner combustion condition systematically, given combustion results on line, and guided the running of the station economically,adding the automation level, improving the safety of the unit frugally with reducing running cost.
