Investigation of the Influence of the Gas Stream Inlet Inclination Angle on the Efficiency of Dust and Ash Collection in Vortex Apparatuses

The model of a traditional vortex apparatus in a program complex is constructed and constructive changes of such apparatuses are proposed. The adequacy of the constructed model in comparison with the existing traditional vortex apparatus is evaluated. The conclusion about the important influence of the design solution on the efficiency of dust collection is made. It is revealed that due to insignificant changes in the angle of inclination of the gas stream inlet, there is an increase in the fractional efficiency, approximately by 4–7 %.
