Cylinder-on-Cone Cyclones with Tangential Inlet

1 Cylinder-on-Cone Cyclones with Tangential Inlet 

In this section we concentrate on cylinder-on-cone cyclones with tangential inlets. To give a feel for the range of Viable designs we list some frequently used designs. We then proceed to give some specific design and construction advice.

Storch and Pojar (1970) performed an interesting and rare study of erosive wear within a variety of steel cylinder-on-cone cyclones with tangential inlets. Erosion rates in each cyclone s cylinder and cone sections were measured as a function of gas inlet velocity and solids concentration for two different types of abrasive dust. The experimental results are illustrated in Fig. 12.1.1, frames a through d. The wear reported is that after exposing the cyclone to a fixed total quantity of dust.

This completes our look at the design of cylinder-on-cone cyclones with tangential inlets. In the following section we discuss the design of cylindrical swirl tubes with swirl vanes. In this discussion, we concentrate on the aspects that are specific to swirl tubes. For the aspects shared between swirl tubes and tangential entry cyclones, much of the discussion above is equally valid for swirl tubes, such as the discussion pertaining to vortex finder configurations. 

A sketch of a standard reverse-flow, cylinder-on-cone cyclone with a tangential, slot-type inlet is shown in Fig. 1.3.1. 

Another assumption made in the models is that the swirl velocity profile (its radial distribution) in the cyclone is constant axially. Figure 4.4.2 shows LDA measurements of the radial profiles of the tangential velocity at a series of axial stations in a cylinder-on-cone cyclone with a conventional slot-type inlet. Figure 4.4.3 shows a similar plot for a swirl tube with a cylindrical body.
