褐煤燃烧污染物排放特性的实验研究

摘要

在对国内外从事此方面研究的工作进展和存在的问题有了详细的了解之后,在自行设计的一台实验室规模的小型循环流化床实验台上对舒兰褐煤燃烧的污染物排放特性做了详细的实验研究和理论分析,阐明了床温、颗粒粒度、Ca/S比、过量空气系数、床料高度、一二次风率等对褐煤流化床燃烧污染物排放特性的影响规律,并结合理论分析和工程实际,对一些参数的选择提出了自己的见解和优化结果。%Most of this paper is based on experimental research,in this respect at home and abroad engaged in research work progress and problems have a detailed understanding of the following,On a self-designed laboratory-small-scale circulating fluidized bed combustion test rig Shulan pollutant emission characteristics of lignite made a detailed experimental study and theoretical analysis to clarify the bed temperature,particle size,Ca /S ratio,excess air ratio,bed material height,a rate of secondary air pollutant emissions from fluidized bed combustion of lignite characteristics of the law,combined with theoretical analysis and engineering practice,the choice of some parameters put forward their own ideas and optimization results.
