CFB锅炉多点排放二氧化硫污染预测

循环流化床锅炉（CFB）多点排放时，直接测量分析对环境的影响较为困难。为了确定其中SO2对环境的影响，通过对鼢在CFB锅炉生产过程中的生成、转化和大气中的扩散分析，建立了多点排放的SO2污染预测正态分布模型。模型结果表明，多点排放时大气SO2的浓度分布仍满足正态分布特征，并较好地反映了最大落地浓度及位置，这对于依据区域大气SO2总量控制，确保和提高设备与工艺系统的清洁生产能力提供了可行依据。

Sulfur Dioxide Pollution Prediction of Multi-Point Emission for CFB Boiler

It is very difficult to analyze influence of exhaust flue gas for circulating fluidized bed boiler on atmosphere by direct measurement because of the complex components of exhaust gas by multi-point emission.To make sure the impact of sulfur dioxide in exhaust gas on atmosphere,the sulfur dioxide pollution prediction model is proposed according to the sulfur dioxide characteristics of creating、translating during the course of industry producing and pervasion in atmosphere by multi-point emission.The model indicates that the distributing of sulfur dioxide concentration in atmosphere by multi-point emission still remains normal distribution,and truly indicates the value and locality of the sulfur dioxide maximal concentration on ground.Feasible gist of insure and improve cleansing throughput for equipments and craftwork systems can obtain from the mathematics model and gross control of sulfur dioxide in certain region.
