摘要
根据对分离器内部流场的测试,分析了分离器内气固运动规律及其对粉尘颗粒捕集分离的影响。利用径向混合模型,导出了描述分离器捕集分离机理的计算模型,并对模型进行了验证。讨论了循环床锅炉飞灰分离器在若干运行工况时的影响因素。
The gas-solid movement in a separator and the eHect ofthemovement on dust particlecollection according to the measurement of the flow field in the separator are analyzed,A cal-culation model for describing the separating mechanism of the separator is developed fromthe radial mixed model. the calculation niodel is verified bv test results. The effect of the op-erating conditions of the fly ash separator in a CFB boiler on the model is also discussed.
