Fine-particle Cleaning With Dense Media. Application of centrifugal action to the heavy medium has permitted the extension of the heavy-medium separation process to particles as fine as 65 mesh. Dense-media Cyclones. The material to be treated, which may range in size from [1 1/4] in. to 35 mesh and typically [3/8] in. X 35 mesh, is pulped with the medium, and this pulp is fed tangentially through the feed inlet(...) to the short cylindrical section [that] carries the central "vortex finder"(...) which prevents short circuiting within the cyclone. Separation is made in the cone-shaped part of the cyclone(...) by the action of centrifugal and centripetal forces. The heavier portion of the feed leaves the cyclone at the apex opening(...), and the lighter portion leaves at the overflow top orifice.

Return Flow Mechanical Atomizing Oil Burners.... This is a register-type burner similar to the mechanical atomizing burners. Wide range is accomplished by use of a return-flow nozzle which has a swirl chamber just ahead of the orifice or sprayer plate. Good atomization is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the oil pump suction. Control of burning rate is accomplished by varying the oil pressure in both the oil inlet and the oil return lines.

La pulvérisation mécanique consiste à porter le combustible à une pression élevée et à dissiper par la tête de pulvérisation l'énergie emmagasinée de façon à rompre la cohésion et à former un faisceau de fines gouttelettes. Le combustible est amené dans une chambre de rotation par des canaux tangentiels, puis il est libéré par l'orifice axial de cette enceinte.

Return Flow Mechanical Atomizing Oil Burners. This [commercial-industrial oil] burner is a modification of a mechanical atomizing burner; atomization is accomplished by oil pressure alone.... The burner was developed for use in large installations such as on shipboard and in electric generating stations.... It is also used for firing large hot water boilers compressed air is too expensive for atomizing oil in large burners.... Wide range is accomplished by use of a return-flow nozzle which has a swirl chamber just ahead of the orifice or sprayer plate. Good atomization is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the oil pump suction. Control of burning rate is accomplished by varying the oil pressure in both the oil inlet and the oil return lines.

Return Flow Pressure Atomizing Oil Burner. This burner is a modification of the pressure atomizing burner; it is also called a modulating pressure atomizer. It has the advantage of wide load range for any given atomizer,... this wide range is accomplished through a return flow nozzle which has an atomizing swirl chamber just ahead of the orifice. Good atomization throughout the load range is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the suction of the oil pump. Control of burning rate is effected by varying the oil pressure in both the oil inlet and oil return lines. Except for the atomizer, load range, and method of control, the information given for the straight pressure atomizing burner applies to this burner.

OBS

Both terms [mechanical atomizing and pressure atomizing] designate atomization of the oil by forcing it at high pressure through a suitable stationary atomizer.
