Figure 10. Maurer (cone) discharges manifest themselves as irregular sparks spreading outward toward the wall from the top of the conical powder heap. They are only active when charged material is being added. (Maurer, 1979.)...

The discharges of static electricity that occur in common industrial processes can be classified as spark, corona, brush discharges, propagating brush discharges, and cone discharges. ... 

For this to occur, all resistances in current loops 1, 2 and 3 for the cyclone on the left side of the figure must be equal to their counterparts on the right side of the figure. These resistances include that of the inlet chute, the wall, the vortex core, the chimney, the plenum chimney and that of the cone discharge opening, for the case illustrated in Fig. 11.5.1. If this conditions is met then,... 

At high solids or liquid loadings (> 10 vol.%, approximately) one must be careful not to unduly restrict the cone discharge opening or the annular space surrounding the vortex stabilizer, if the later are employed in the design. In some cases it may be necessary to eliminate the cone altogether and install a purely cylindrical-bodied cyclone. 

Flow Nozzles. A flow nozzle is a constriction having an eUiptical or nearly eUiptical inlet section that blends into a cylindrical throat section as shown in Figure 8. Nozzle pressure differential is normally measured between taps located 1 pipe diameter upstream and 0.5 pipe diameters downstream of the nozzle inlet face. A nozzle has the approximate discharge coefficient of an equivalent venturi and the pressure drop of an equivalent orifice plate although venturi nozzles, which add a diffuser cone to proprietary nozzle shapes, are available to provide better pressure recovery. 

A number of chemiluminescent reactions have been studied by producing key reactants through pulsed electric discharge, by microwave dissociation, or by observing the reactions of atoms and free radicals produced in the inner cone of a laminar flame as they diffuse into the flame s cool outer cone (182,183). These are either combination reactions or atom-transfer reactions involving transfer of chlorine (184) or oxygen atoms (181,185—187), the latter giving excited oxides. 

The area of influence of a vibrating discharger is limited to a cylinder, the diameter of which is roughly equal to the top diameter of the discharger. Hence, if a vibrating discharger is mounted onto a conical hopper section, flow is confined predominantly to a central flow channel located directly above the discharger. This is tme unless the slope and smoothness of the static cone meet requirements for mass flow, or the diameter of the flow channel exceeds the critical rathole diameter for the material. 

Rinse is shown only in the basket centiifuge because linse efficiency in the cone screen is faidy low compared to the basket. The latter may be selected for the apphcafion if good rinsing is needed, and the conveyor-discharge conical screen centrifuge selected if no rinsing is necessary.
