| Abstract: | By using computational fluid dynamics (CFD) method, the gas flow distribution of a large straight through baghouse in the coal-boiler power plant was analyzed numerically.Through numerically analyzing gas flow distribution in the tank body,air volume of every filter bag cell,head-on gas flow velocity distribution of filter bag were demonstrated.The calculated results were better consistent with the model experiment and the measured results in the field.And the results can be as the basis for optimizing structure design of baghouse. |
