一种基于炉膛压力分析的燃烧特征信号提取方法

考虑到燃烧系统的耦合特性,采用机理分析方法,建立了炉膛压力的动态模型,通过仿真实验验证了模型的有效性和准确性.此模型可解除耦合,消除通风平衡影响,得到炉膛压力与燃烧的唯一对应关系.同时利用此方法可得到锅炉燃烧的特征信号,为研究燃烧优化提供了理论和实践基础.

One Extraction Method of Combustion Feature Signal Based on Furnace Pressure Analysis

This paper adopted the method of mechanism analysis to establish the dynamic model of the boiler furnace pressure considering the coupling of combustion and verified the effectiveness and accuracy of the model by simulation result.With the model,the coupling can be lifted and the impact of airiness balance can be eliminated,then the only correspondence between furnace pressure and combustion can be found.At the same time using this method will receive the boiler combustion feature signal such as temperature...
